Before purchasing tile adhesive, you should study its composition. Among the wide variety of market offers, it has become very difficult to understand which adhesive for slabs fits better Total. What should you pay attention to when purchasing glue? Not so long ago, tiles were laid only on a solution of cement and sand, which was obtained following certain proportions. Experienced craftsmen added PVA glue to the mixture to obtain increased tenacity. If we talk about modern compositions, then not all also include these components and various modifying additives. It is these additives that allow the tiles to stay in place for many years.
GOST tile adhesive: main indicators
All presented adhesive products may differ in their composition, however, according to GOST standards, they must satisfy certain requirements. When purchasing glue, it is very important to pay attention to its technical properties.
The characteristics of tile adhesive are often indicated on back side packaging
According to GOST, the main technical characteristics include 8 indicators:
- Strength indicator - it indicates maximum load, which the surface will perceive;
- Density indicators are a value that is measured in g per m2 and shows the maximum weight of the adhesive mixture;
- Shrinkage process - indicates the deformation of the surface in the event of the influence of certain factors.
- Viscosity indicator - shows the number of adhesive-type components in the material, as well as the likelihood of attaching the cladding without displacement of the base;
- Drying time - shows the shelf life, since the frozen mixture is unsuitable for use;
- Material consumption always depends on density; for calculation, take the mixture and divide it by 1 m2 of area,
- Plasticity indicator - thanks to this data, you can determine how well the mixture is applied and whether it crumbles;
- Water resistance parameters - indicate how the mixture will behave if moisture gets on it;
- Adhesion indicators - indicate the quality of adhesion with a certain type surfaces.
All of the above indicators according to GOST must be taken into account when purchasing any adhesive composition for working with tiles.
Choosing tile adhesive: technical characteristics
When you choose adhesive composition for ceramic tiles, you definitely need to know it specifications. If the composition does not meet the data in accordance with GOST, which are listed above, it should not be purchased under any circumstances. IN in this case No one will give you a guarantee that the tile will hold securely and will not fall off.
Before purchasing tile adhesive from a particular manufacturer, you should read reviews about it on the Internet.
- Plasticity index. It should be moderate. If the glue spreads too much, it will be impossible to make the desired layer. The plasticity of the composition should not change, regardless of whether it is thick or sparse.
- Spreadability. When choosing glue, you need to remember that when applied it must fill all the voids. Otherwise the tile will fall off.
- Adhesion indicators. The glue must withstand any weight of material. It would be great if the adhesive composition is equipped with fast adhesion, this is especially true for slabs with large weight and size.
- Slow release of moisture. During installation it should always be possible to correct the work, so the glue should dry as slowly as possible. In this case, it will gain greater strength.
All these indicators are very important. Without them, work will either be too difficult or impossible. That is why, before purchasing, be sure to read all the manufacturer’s instructions on the packaging.
Composition of tile adhesive: main varieties
An important indicator is the composition of the tile adhesive. The quality of the work ahead directly depends on its components. If we talk about what types of glue exist, they can be divided into certain classes due to certain compositions.
Namely:
- Cement based adhesives. They are the most budget-friendly and are in great demand. It consists of sand and cement, in addition it contains polymer components that increase density, water resistance, compression and adhesion. All components in this composition are hypoallergenic. This brand of glue is optimal for long-term storage.
- Dispersion type adhesives. It is distinguished by an increased price compared to the previous type. Used for attaching tiles to non-standard surfaces without priming or sanding. Sold in finished form. Most often, glue of this brand can be purchased from the manufacturer Tokan.
- Epoxy adhesive. The consistency is multi-component. Before you start using it, you need to introduce a catalyst, which makes the substance very strong compared to the rest. It is not affected by alkaline components, solvents, moisture or temperature changes due to the fact that it contains specific kPa.
- A relatively new adhesive composition is liquid nails. The composition includes polymers and synthetic rubber. This material is highly durable, but is not suitable for use in rooms with high humidity.
Tile adhesive should not contain harmful substances
Most often it is used for the restoration of ceramic coatings.
Shelf life of tile adhesive: what is it and how to calculate it
Recently, consumers are increasingly angry about purchasing expired mixtures for laying slabs, especially if it is a bulky material.
When purchasing material, pay attention to the production date. It is this indicator that is the starting point for the expiration date, and not the date of purchase.
This applies not only to tile adhesive mixtures, but also to any other material.
It is very important to consider that before you purchase the mixture, it is still certain time was in the manufacturers' warehouse, and only then ended up on the counter of a hardware store. Therefore, you must definitely count on the fact that the purchased adhesive mixture must be used before the deadline will pass expiration date specified by the manufacturer.
The shelf life of tile adhesive depends on its composition and type of packaging.
Of course, we can’t talk about the importance of the shelf life of a building material, as we can about a food product, but still, it is important point upon purchase.
For example, dry mixtures of cement, sand and polymers can be stored from six months to a year. This period is calculated based on the time when all the components can retain their qualities. If after this period the mixture was not used, but it was stored under the right conditions, then it will lose its quality by 5%, and this will happen every month. As for polymers, they completely lose their basic properties.
It must be remembered that each type construction mixture has its own shelf life. For example, dry and ready-made glue have different suitability indicators, it depends on which manufacturer is chosen and what base the glue has.
Optimal composition of tile adhesive (video)
Regardless of the difficulties that may accompany your renovation process, you need to choose the best adhesive for ceramic tiles. After all, this will determine how well the material will be glued, as well as how durable your finish will be. Do not rush to rush to extremes and purchase a universal type of glue, because it also has its limits, no one can guarantee perfect quality. Think through everything down to the smallest detail, because the final result depends on everything, even on the room in which the work will be carried out.

Tile adhesive is the second most important material, the quality and properties of which determine the final result when tiling surfaces. The range of adhesive compositions offered by modern manufacturers is wide, so without knowing the specific characteristics various types adhesives and comparing them with GOST requirements, it is difficult to make a choice in favor of a specific material.
In order for the tile adhesive to reliably hold the cladding, it is important to maintain the technical characteristics of the mixture in accordance with GOST
To choose the right mixture, consider the following questions:
- general requirements for adhesive mixtures;
- groups of tile adhesives;
- properties and areas of application.
General requirements for tile adhesive
All types of adhesive mixtures for laying tiles must have a certain set of necessary technical characteristics, which, depending on the type of adhesive, may differ in value. Let us list these properties.
During operation (before the solution hardens):
- ease of preparation;
- elasticity (should fit well on the surfaces to be glued);
- sufficient lifespan (the ability to work out the prepared amount of mixture, correct displaced tiles before the glue hardens);
- high adhesion (adhesion of the solution to the surfaces of the material and base);
- low fluidity and resistance to slipping (holding the tiles in place on a vertical surface).
First of all, the glue must have increased water and frost resistance.
After the tile adhesive has cured:
- compressive and shear strength;
- water resistance;
- heat resistance;
- frost resistance;
- resistance to chemical agents;
- elasticity (the ability to absorb the stresses of the cladding material that arise when temperatures change).
Groups of tile adhesives
Based on the material of their components, all adhesive mixtures for ceramics are divided into 3 groups:
- compositions for cement based;
- water-dispersed solutions;
- polyurethane adhesives;
- adhesives based on epoxy reactive resins.
Let's look at these groups and their subgroups.
Cement-based compositions
Cement-based adhesives are a dry mixture of cement, sand and certain chemical components, the set of which may vary. The requirements for the technical characteristics of cement adhesive mixtures are set out in GOST 31357-2007 “Dry building mixtures with a cement binder. General technical conditions", GOST 31358-2007 "Dry construction floor mixtures with cement binder. Specifications" and GOST 4.233-86 "Construction mortars. Nomenclature of indicators".
Tile cement adhesive is a dry mortar
Characteristics
These adhesives, depending on the variety, are intended for finishing external and internal surfaces with tiles made of natural and artificial materials. Standard packaging of the mixture is 25 kg bags.
The specific gravity of the dry material is on average 1.3 g/cm3, the density of the ready-to-use solution is 1.8 g/cm3.
The compressive strength of fully cured adhesive, according to GOST, must be more than 10 MPa for universal compositions and at least 15 MPa for materials marked “Elastic”, “With increased fixation” and “For floors”.
The composition of the tile adhesive is mixed with water according to the instructions clearly stated on the packaging and used in two ways - by applying it to ceramics and laying it on the surface of the base. The cement in the solution is gray or white (for glass tiles and mosaics made of smalt) flowers.
Cement-based adhesive solutions retain water during the hardening process, allowing the joints to be grouted within 24 hours, while the adhesive gains full strength within up to 2-3 weeks.
Shelf life
When purchasing such mixtures, you should pay attention to the release date of the material, since after the expiration date, lumps form in the composition due to hygroscopicity. The shelf life of such mixtures in the manufacturer's packaging ranges from 6 to 9 months, so when purchasing, you must take into account that this period must expire before the repair is completed - each overdue month deprives the cement of 5% of its activity, and the polymer components may generally lose their properties.
Cement adhesive mixtures, in turn, are divided into 2 subgroups:
- thick-layer (leveling);
- thin-layer.
Thick-layer cement adhesive mixtures
These mixtures are used to level the base under the tiles if the differences in surface levels are 1-3 cm. The use of such compositions allows you to avoid plastering the base and reduce repair time.
To provide long term operation, it is important to choose the right adhesive composition
The composition of the leveling adhesive, which includes cement, sand of various fractions and a set of polymers, ensures the strength of laying tiles made of any material. “Reinforced” grade material is used even for installation of cladding made of natural stone and porcelain stoneware, specific gravity which because of high density one and a half to two times the weight of conventional ceramics. Varieties of thick-layer adhesives for external and interior works, for rooms with high humidity and high temperature air.
Compressive strength index thick-layer adhesives after complete drying it must be at least 10 MPa.
The disadvantage of leveling mixtures is their strong shrinkage, which makes it difficult to calculate the need for material and does not make this method of leveling surfaces economical.
Thin-layer cement-based adhesives
Thin-layer cement-based adhesives are used for laying tiles on surfaces whose level differences do not exceed 1 cm.
The layer of glue applied to the back side of the ceramic must be at least 5 mm. As in leveling mixtures, thin-layer compositions use special additives that increase individual characteristics material necessary for its use in specific conditions, but the specific gravity of the adhesive changes slightly from this. Varieties of such adhesives with enhanced adhesion and strength for laying heavy tiles also exist.
The compressive strength of thin-layer compositions after drying should not be lower than 10 MPa.
The advantages of thin-layer mixtures are low consumption (1-1.5 kg per 1 square meter) and shorter drying times than thick-layer mixtures.
The disadvantage is low moisture resistance and there is no “moisture resistant” marking, which forces the use of only moisture-resistant mixtures.
Water-dispersion (polymer) adhesives are one-component aqueous solutions of polymer particles based on acrylic, latex or polyvinyl acetate (PVA). Used for cladding ceramic tiles leveled concrete, plastered and plasterboard bases, forming a waterproof shell. Sold in sealed plastic containers of various sizes. The specific gravity of the ready-to-use solution is approximately equal to the weight of the cement-based adhesive and is 1.3 g/cm3; the same value is taken as the density.
The technical characteristics of such adhesive compositions are regulated by the requirements of GOST 28780-2004 “Polymer adhesives. Technical conditions" and GOST 12172-74 "Phenol-polyvinyl acetal adhesives. Technical conditions".
Dispersion adhesive is a composition of tile adhesive based on water based, which includes acrylic or cellulose-glycolic acid and special additives - chalk, latex
These materials are produced in the form of thick white, colored solutions and pastes. Glue particles suspended in water when the water evaporates or goes into the base are connected to each other and form an adhesive film.
Instructions for use are usually presented on the container in an accessible form.
Advantages:
- ease of preparation for use;
- ease of application;
- connection strength;
- high moisture resistance;
- heat resistance;
- low consumption;
- absence of flammable components in the material;
- long shelf life when stored in airtight containers;
- environmental friendliness.
Flaws:
- impossibility of use for leveling surfaces;
- high price compared to cement adhesives.
Water-based adhesive is the most common on the market
Polyurethane adhesives
Polyurethane-based adhesives are one- or two-component compositions. The technical characteristics of these adhesives must meet the requirements of GOST 30535-97 “Polymer adhesives. Nomenclature of indicators".
Curing of one-component compositions occurs due to moisture environment, reacting with the components of the solution. Two-component substances harden when the components are mixed in a certain ratio.
It must be taken into account that some types of polyurethane adhesive expand during curing and are therefore unsuitable for laying tiles.
The material has high strength, sufficient elasticity and resistance to impact chemical substances. Effectively bonds surfaces of even dissimilar materials together (metal - glass, stone - wood), has almost zero moisture absorption, and is insensitive to large differences temperatures (from -50 to +120 degrees Celsius) and pressure. The composition, in addition to a strong connection of materials in a short time, provides waterproofing of the base.
Industrially produced one-component and two-component polyurethane adhesive
The adhesive solution is applied with a brush or roller not to the tile, but to the base. A necessary condition The strength gain of polymer glue when used is thorough mixing of the solution and precise adherence to the proportions of the components in a two-component design.
Advantages of the material:
- strength and durability of the connection;
- high adhesion to any surfaces;
- moisture and heat resistance (suitable for underfloor heating);
- resistance to chemicals;
- rapid strength gain (possibility of repairs in a short time);
- the ability to choose a variety of glue for specific conditions without overpaying for versatility;
- low consumption and no shrinkage;
- environmental friendliness after hardening.
Flaws:
- The need to have skills in using this glue;
- The presence of a pungent odor in some varieties;
- Relatively high price.
When working with polyurethane glue, you should wear protective gloves, and if the solution gets on your skin, wash it off immediately warm water with soap.
Epoxy adhesives are divided into two- and multi-component. Solvent-free epoxy adhesive consists of a resin (the main binder) and a hardener (a liquid or powder activator). Binder mixed in a certain proportion with a hardener, after which the mixture is applied to the grease-free surfaces of the tile or base, and the product is glued in place.
A mixture of synthetic resin, mineral fillers and organic additives, hardening due to a chemical reaction
The setting time of the adhesive is approximately 20 minutes, and complete curing occurs after a few hours. The surfaces to be bonded must not be porous. IN difficult cases To increase strength, epoxy adhesive is reinforced with dry powdered fiberglass.
These adhesives have high technical characteristics, and therefore are used in critical places and in industries with aggressive finishing operating conditions.
The compressive strength of compositions based on reactive resins must be at least 15 MPa.
Advantages:
- high strength with low demands on the thickness of the adhesive layer;
- elasticity and high adhesion;
- waterproof;
- frost resistance;
- long shelf life;
- low specific gravity (1300-1500 kg/m3);
- no shrinkage.
Flaws:
- flammability;
- high price.
Conclusion
Having decided which type of glue to use for repairs, it is advisable to write down from GOST the characteristics that this material should have, and when purchasing, compare them with the data, albeit incomplete, indicated on the packaging. The shelf life is calculated from the date of production of the material, and not from the date of purchase.
In work Eunice tile adhesive plus expiration date, based on the inscription on the package, came out on March 18, can it be used in work?
- Almost all bags of dry mixtures are made with a plastic liner to prevent it from getting wet.
- Of course, if it was stored properly.
- Easy if he looks normal
- If it was stored in normal conditions, then you can without any doubt. Go for it))Source: Personal experience
- depending on the volumes, this may not happen, and it is undesirable to follow the expiration date
Check if the mixture in the bag is homogeneous; it should be free of lumps and stones.
As for the deadlines, they are not strictly until the expiration date, that is, on the 17th there was still normal glue, but on the 18th the stake stood up)
The terms are conditional, minus a month, but not six months or a year)
Topic: Tile adhesive has expired
Five bags of tile adhesive have been lying around for about a year; we already bought it for repairs, but it took too long and we can’t get there. It says on the bag that the expiration date is six months from the date of manufacture. If you still use this “expired” bathroom adhesive, what do you think?
Well what can we say? It's expired!!! Although I did such experiments at home with “Yunis” it hasn’t fallen off yet. But I still won’t advise anything, you know, anything can happen :-) And yet I believe that if everything was stored in a dry room, then nothing should happen
2kvartirant For about 3 years, the “forgotten” 5 kg of Vetonit KL FIX lay in the pantry - it was caked into a gray mass that was difficult to crush with your fingers.
Typical cement slab. glue - cement, sand, additives. There will be nothing for sand, cement “cakes” over time, loses activity by 5% per month, it’s hard to say what happens with polymers.
In such a case, I simply bought more of the same fresh glue and mixed the old with the new.
There is PLUS glue, production date is 04/30/2009. Guarantee period storage 6 months, stored in room conditions, the bags were not opened, the mixture compacted slightly, but after shaking the bag it loosened.Now it’s a shame to throw it away, but I’m afraid.
It is necessary to check the adhesion (the “penetration - setting” force of the glue). Dilute a little the required proportion and connect two pieces\pebbles of expanded clay, wait until it dries and check for tearing. ******
In principle, when proper storage The glue can be stored for 1 year. However, if moisture gets in, it won’t last even a week.In general, I will repeat the classics - nothing lasts forever.
Somewhere I thought so, a test batch, put tiles on it, wait a week, and then see the results.
I had experience working with Yunis+, which was stored in a dry, heated room for a year and a half. It even seemed to me that it became easier to knead. You may also need a sieve so that the caked pieces do not spoil the batch.
Your words are like a balm for the soul. Will the tiles not fall off over time?
You understand that I can’t promise anything - I hope not. I’ve had it for almost a year now - everything is fine. The main thing is to prepare and lay the base according to technology.
2bardak Eunice's glue is already below average, and even expired. You don’t have a whole pallet, probably 3 bags.
******No, it’s not a pallet, but the toad is pressing, especially since the tiles have already been laid with new glue, the bags will last for another six months and then you can throw them away.The situation is not hopeless.
1. Buy latex additive IDROKOL X20 (LITOKOL), at the rate of 2.5 kg of IDROKOL X20 per 25 kg of dry adhesive mixture.
2. Mix 2.5 kg of IDROKOL X20 with 4.5-5 liters of water.
3. Use the resulting liquid to mix 25 kg of dry adhesive mixture (expired).
4. Lay the tiles.
5. The result is SUPER!According to GOST, they are stored for 6 months (such requirements), if they are released (and are released) according to the specifications, then they set it to 12 months. There are changes, but not fatal, Eunice + is not exactly junk (from Eunice), additives are normal there.Knauf - forum - dry mixes - flesenklib tile adhesive has a real shelf life...
What is the actual shelf life of Flesenkliber tile adhesive?
I bought this bath glue and rented a car because... you need a lot of bags.
And only at home I noticed that the release date was 04.05, i.e. this glue already more than a year, and the shelf life is 6 months :(
If the glue is crumbly, i.e. It feels like it hasn’t petrified there, can I use it? or should I return it and take it to the seller??Shelf life of tile adhesive
1. Jorik, with such thickness you have one square meter It will take 1.5-2 bags of glue. Isn't it too expensive? It might be cheaper to make a cement screed sand mixture, and then put it under the comb? Calculate the costs for the entire garage area!
2. Do not experiment with imported adhesives! If it says 2-6mm, then there is no need to make it thicker, otherwise, residual deformations that occur in tile adhesives for 2-3 weeks will simply cause the tiles to peel off (thick ones take longer to dry, and accordingly, additives, mineral and basic, will work component of the adhesive - cement, does not occur at a certain, calculated time, but with a delay. For example: the reaction time of the additives is 3 hours, and the cement will begin to harden due to large thickness not in 3 hours, but in 4-5 hours. So it turns out that both the cement and the additives were supposed to work at the same time and increase strength, but they worked at different times and interfered with each other.) Well, I said the operating hours offhand so that it would be clear. Exactly what response times are and how they are calculated is, excuse me, a secret of the manufacturer. I had one like this personal experience in the 90s. At that time I worked mainly with Atlas and Bolex adhesives (at that time we were just starting to import all these adhesives and few people knew how to work with them because instructions were not printed in Russian). Due to inexperience, I tried to increase the thickness of the layer, tried to add cement to save money (when the layer is thick, a lot is wasted and the client asks to save). In general, all the experiments backfired... Now I am acting strictly according to the instructions. I didn’t invent this glue, and it’s not for me to break it! Although with Russian adhesives UnisХХI and Starateli, this option works
In the process of construction and repair work glue must be used. With its help, certain materials are laid and finishing is carried out. For example, tile adhesive specially designed for this purpose is used to lay tiles. Tile adhesives on the market building materials quite a lot - from different companies, different brands, different characteristics and qualities. Therefore, the choice of one option or another is sometimes very difficult.
Among so much variety tile adhesives You should highlight the glue “Unis Plus”. This is an adhesive that appeared on the building materials market back in 1994 and quickly began to enjoy the trust of professionals in this field. Today, Unis Plus tile adhesive is sold throughout Russia and the CIS countries, and is also supplied to the country's leading construction companies. Speaking about the production and sales volumes of adhesives of this brand, it should be noted that they occupy about 27% of the market, which in itself is an indicator of their popularity.
Such a high demand for Unis Plus tile adhesives can be explained quite simply - they have many positive qualities and characteristics that bring them to the forefront among their analogues.
Main characteristics of tile adhesive "Unis Plus"
When choosing a particular material, experts pay attention to its characteristics and basic properties. Tile adhesive “Unis Plus” has numerous qualities that you can’t help but like professional builder who does his job conscientiously. This: - increased traction;
- moisture resistance;
- frost resistance;
- weather resistance;
- ease of use;
- elasticity
- excellent strength characteristics
- environmental friendliness and safety
- The optimal weight of a package of “Unis Plus” glue is 25 kg.
Ease of use
One of the most important properties The advantage of the Unis Plus tile adhesive (25kg) is that it can be used on complex and old surfaces. It could be old tiles, a layer of previous glue and other surfaces - in all cases, reliable and durable adhesion of the glue will be guaranteed. This provides additional convenience for working with this material, as it saves time on cleaning surfaces and preparing them for application. new tiles. In addition, excellent adhesion characteristics allow the tiles to be laid from top to bottom, without the risk of uneven and poor-quality installation. Tile adhesive "Unis Plus" can be used on any surface - brick, plaster, cement, concrete and others, which is also its a huge advantage. Adhesives of this brand can also be used when installing heated floors - when heated, it does not lose its adhesive properties.Surface preparation
In order for the tiles to last long and reliably, the surface should be prepared before applying Unis Plus adhesive. Debris and any dirt, dust, moisture, oil stains should be removed - all this prevents reliable adhesion of the glue to the base.
To achieve even greater reliability of adhesion and durability of the laid tiles, before applying glue to the surface, it should be leveled using products specially designed for this from the same manufacturer. In this case, not only excellent adhesion of the glue is guaranteed, but also perfectly even laying of the tiles on the surface.
Tile adhesive "Unis Plus" - price
When choosing a particular material, the question arises not only about its characteristics and properties, but also about price. After all, it is very important that the cost of the material is fully justified by its qualities. Speaking about such a material as Unis Plus glue, the price in this case not only corresponds to its qualities and advantages, but also, one might say, is low in comparison with the advantages that it has this material. Therefore, by choosing “Unis Plus” tile adhesive, the price of which is very reasonable, every builder will benefit from both material point both from the point of view and from the side of choice as much as possible quality material.Thus, when choosing adhesive for laying tiles, you should carefully consider a brand such as Unis Plus. Throughout its existence, this company produces exclusively high quality products, and tile adhesive is no exception. No wonder the presenters construction companies For the most part, adhesives of this brand are used in the process of construction and repair work related to laying tiles. We advise you to give preference to the exceptional quality that is inherent in the entire line of building materials from this manufacturer.
Plitonit B+ glue is expired by 9 months, AQUASTOP CLASSIC primer is expired by 1.5 years.
Stored in a dry non-residential apartment.
Is it worth using them, or is it better to throw them away?
Of course, it would be a pity to throw away the material; I took it with a reserve.
Thank you.
The cement in the glue has most likely lost its mark. As if such savings wouldn’t backfire later...
No responsible work. Expired glue can be added to any cement mortar (for screed, plaster). At the same time, you shouldn’t just mix them with cement - the solution will be too loose and soft after drying. The primer is worth opening and smelling. If there is no distinctly rotten smell, it can be used for all sorts of strange things for which primers are usually a pity - between layers of putty or under wallpaper. Overdue gypsum plaster You can give it to electricians. There is no other way to use it other than plaster. Even if you use all sorts of ancient tricks, such as dilution with glue. It hardens slowly, yes. But the work is hard and the result is suspicious - she babbles, as if she wasn’t stuck at all.
Thanks everyone.
d_redkin this film is the one under plastic cover be?According to your criteria, the primer seems to be normal, although there are a few small lumps.
Maybe strain it?According to the instructions, the primer should be diluted 1 to 5, what ratio can you recommend?
- for application to a wall plastered with TsPS using putty
- For the second layer of putty?
- Before wallpapering?
The lumps are crushed.
Thanks for the extended answer.The shelf life of the glue has expired - light fixtures: finishing with block house and imitation timber, finishing with clapboard and installation of floors

You understand that I can’t promise anything - I hope not
I've had it for almost a year now - everything is fine. The main thing is to prepare the base correctly and lay it according to technology.
Study, study, study!Guaranteed shelf life 6 months, stored indoors, bags have not been opened
Everything should be fine, since it seems like 6 months for outdoor storage, but you have it in a dry room.
Best regards, Evgenievich.2bardak and so the glue is below average, and even expired. You don’t have a whole pallet, probably 3 bags.
Floor screed. Good luck to all!No, it’s not a pallet, but the toad is pressing, especially since the tiles have already been laid with new glue, the bags will last for another six months and then you can throw them away.
the bags will sit for half a year
If you still keep it, throw it away or give it as a gift.
Post an announcement at the entrance. At least you can drink beer and don’t have to carry it around. It is not worth saving perishable goods.
Everything has already been invented, not everything has been thought out yet.Eunice glue is already of below average quality
Well, he's not that bad. Regular glue from the "nothing special" category. There are better ones, but they also correspond to them.
but the toad presses
So you were going to sell it... I was thinking of using it for myself. Well then the price really should be symbolic or beer|juice
I just don’t understand why all sorts of trial batches are then - this is no longer your headache.
Study, study, study!So you're planning to sell it?
No, there’s no point in selling three bags, although I love beer. Especially a bath
I’ve already installed it with a special one using fresh glue, but my hands are itching

Topicstarter didn't say anything about mosaics - neither did I. Maybe he wants to glue porcelain tiles to the ceiling, I don’t know
There are other adhesives for mosaics, and for porcelain tiles too. And this implies that the author is going to glue ordinary tiles in non-extreme conditions. On "expired" Eunice - why not?
Study, study, study!According to GOST, tsem adhesives are stored for 6 months (such requirements), if produced (and produced) according to specifications, then they set it for 12 months. There are changes, but not fatal, Eunice + is not exactly junk (from Eunice), additives are normal there.
The author is going to glue ordinary tiles in non-extreme conditions. On "expired" Eunice - why not?
But in general, try (carry out a test gluing!), you can, as already written, glue the tile and wait 3 days, then try to tear it off.and my hands are itching

Application area - :
Tile adhesive Ceresit CM 11 designed for fastening ceramic and stone tiles with water absorption greater than or equal to 3% and up to 30x30 cm in size on non-deformable bases, on walls and floors, inside and outside buildings, in civil and industrial construction.
Tile adhesive Ceresit CM 11 Suitable for use in continuous and periodic exposure to water.
Allowed to use tile adhesive Ceresit CM 11 for fastening tiles with absorption less than 3% (ceramic granite, clinker, stone, etc.) only inside buildings on unheated floors that meet the requirements of 2.03.13-88 (mainly in residential and administrative premises).
In the case of deformable bases of heated screeds and other complex bases, it is recommended to use highly elastic adhesive CM 17 or adhesive CM 11 prepared with the addition of liquid elasticizer CC 83.
Tile adhesive Ceresit CM 11 with the addition of elasticizer CC83 should be used:
for fastening tiles with water absorption of less than 3% (ceramic granite, clinker, stone, etc.) on floors for exterior work and walls;
on heated screeds;
on plinths, parapets, external stairs, entrance groups, floors of balconies, terraces, exploited roofs;
in open, as well as in fairly large indoor tanks and pools;
on deformable bases (chipboard, plasterboard, OSB and other boards);
on ceramic (including glazed) cladding for external and internal work;
on durable paint coatings with good adhesion;
on gypsum and anhydrite coatings with good adhesion;
on gypsum and anhydrite bases;
on light, cellular and “young” (“age” less than a month) concrete.
For laying tiles made of marble and light translucent stone, as well as for glass mosaics, it is recommended to use stone ceresit cm115">white glue for Ceresit stone CM 115.
For laying large format tiles on floors, it is recommended to use tile adhesive Ceresit CM 12.Preparing the base:
The base must meet the requirements of SNiP 3.04.01-87 and have sufficient bearing capacity. The base must be dusted and cleaned of substances that reduce the adhesive adhesion (efflorescence, fats, bitumen, etc.). Unstable crumbling areas must be removed.
It is recommended to pre-level the walls repair plaster Ceresit CT 29 at least 3 days before fixing the tiles, and floors - leveling mixture Ceresit group CN. Irregularities up to 5 mm can be leveled with CM9 at least 1 day before fixing the tiles.
Typical bases ( glue Ceresit CM 11)
Cement-sand and cement-lime plasters, cement-sand screeds (age more than 28 days, humidity less than 4%) are recommended to be treated primer Ceresit CT 17 and dry for at least 4 hours. Dense, clean, solid foundations It is allowed not to prime.
NOT Typical grounds ( glue Ceresit CM 11 + CC83)
Gypsum plasters (humidity less than 0.5%), wood chips, cement-bonded particles, gypsum boards and other boards (thickness more than 22 mm), light, cellular or “young” (age about 1 month, humidity less than 4%), cement- heated sand screeds should be primed with CN 94 or CT 17 and dried completely ( OSB boards prime with CN 94).
Stone and ceramic cladding, water-dispersed paint coatings with good adhesion to the base, cast asphalt screeds must be treated with CN 94 primer and dried for at least 2 hours.
Execution of work:
For cooking mortar mixture take exactly measured amount clean water(from +5 to +20 degrees) or elasticizer CC 83, diluted with water in a ratio of 2:1. The dry mixture is gradually added to the liquid while stirring, achieving a homogeneous mass without lumps. Mixing is done using a mixer or drill with an attachment for viscous mixtures at a rotation speed of 400-800 rpm. Then a technological pause of 5 minutes is maintained for the mortar mixture to mature and mixed again. The mortar mixture must be used within approximately 2 hours (with elasticizer CC 83 in 1.5 hours) from the moment of preparation.
The glue is applied to the base with the smooth side of a notched grater or a smooth trowel and spread over the surface with the notched side of a grater or a notched trowel. The teeth must have square shape, and their size is chosen depending on the format of the tiles (see table below). At correct selection Depending on the consistency of the mortar mixture and the size of the trowel teeth, the glue, after pressing the tiles, should cover at least 65% of the glued surface on the walls and 80% on the floors.
Attention! Do not pre-soak the tiles!
The tiles can be fixed within 15 minutes (" open time") after applying glue to the base (with an elasticizer for 20 minutes). The tiles are laid on adhesive layer and pressed to the base. The position of the tiles can be adjusted within 20 minutes after laying (with an elasticizer - 25 minutes).
Attention! You cannot lay tiles end to end!
The width of the joint is set depending on the tile format and operating conditions. The high fixing ability of the glue allows you to do without spacers between the tiles to ensure the same seam width.
For exterior work and installation of stone cladding, to increase the reliability of fastening the tiles, it is recommended to use a combined laying method: glue is additionally applied with a smooth spatula to the mounting surface of the tiles in an even layer 1 mm thick. glue increases by 0.5 kg/m2.
It is recommended to fill joints with appropriate grouts Ceresit group CE no earlier than 24 hours after laying the tiles. When using adhesive with the addition of an elasticizer, it is recommended to fill the joints with elastic grout CE 40 no earlier than 72 hours after laying the tiles.
Fresh glue residues can be removed with water, dried ones - only mechanically.Recommendations:
Work should be carried out in dry conditions, at air and base temperatures from +5 to +20 degrees and relative humidity air less than 80%. All the qualities and recommendations stated in the technical description are correct for ambient temperatures and relative air humidity up to 60%. In other conditions, it is possible to change the consumption time, adjustment and open time of the glue, as well as the time the cladding is ready to fill the joints.
In cases not mentioned in this technical description, it is recommended to use other adhesives Ceresit CM or CU groups. Tile adhesive Ceresit CM 11 contains cement, and when interacting with water it gives an alkaline reaction, so when working with it it is necessary to protect your eyes and skin. If the mixture gets into tile adhesive Ceresit CM 9 If you get into your eyes, rinse them with water and seek help from a doctor.

Shelf life of tile adhesive
1. Jorik, with such a thickness, you will need 1.5-2 bags of glue per square meter. Isn't it too expensive? Is it cheaper to make a screed from a cement-sand mixture, and then put it under the comb? Calculate the costs for the entire garage area!
2. It’s better not to experiment with imported adhesives! If it says 2-6mm, then you don’t need to make it thicker, otherwise, residual deformations that occur in tile adhesives for 2-3 weeks will simply cause the tiles to peel off (a thick layer takes longer to dry, and accordingly, additives, mineral and the main component of the glue - cement, does not occur at a certain, calculated time, but with a delay. For example: the response time of the additives is 3 hours, and the cement will begin to harden due to its large thickness not after 3 hours, but after 4-5 hours. So it turns out , that both the cement and the additives were supposed to work at the same time and increase strength, but they worked at different times and interfered with each other.) Well, I said the operating hours offhand so that it would be clear. Exactly what response times are and how they are calculated is, excuse me, a secret of the manufacturer. I had such personal experience in the 90s. At that time I worked mainly with Atlas and Bolex adhesives (at that time we were just starting to import all these adhesives and few people knew how to work with them because instructions were not printed in Russian). Due to inexperience, I tried to increase the thickness of the layer, tried to add cement to save money (when the layer is thick, a lot is wasted and the client asks to save). In general, all the experiments backfired... Now I am acting strictly according to the instructions. I didn’t invent this glue, and it’s not for me to break it! Although with Russian adhesives UnisХХI and Starateli, this option works
