The varnished surface of the table is very aesthetically pleasing, practical, and also functional. A layer of varnish helps protect the surface and also prevents destruction, as it protects the wood well from moisture and other damage. Varnishing is especially important for worktops in the kitchen - wooden countertops are constantly exposed to mechanical stress and moisture. Let's see what varnish is used for a wooden table, how to properly prepare a wooden surface, and also how to apply the varnish correctly.
Kitchen and other furniture is made mainly of wood. The wood can be natural or it can be various materials made from shavings - these are MDF, chipboard, fiberboard and others. Tables can be without any coating or the surface can be treated with paints and varnishes.
Among the main advantages of wood are high thermal insulation, attractive and aesthetic appearance, a huge number of forms, ease of restoration measures. Along with the advantages, there are also disadvantages - wooden surfaces They get dirty very quickly, the material is quite flammable, and is easily scratched due to even minor mechanical damage.
Also, the disadvantages include high price table tops made of natural wood.
How to protect a wooden table?
The work area in kitchens is exposed to various liquids every day and is in constant high humidity. In order for furniture to serve for many years, it is necessary to protect it from moisture.
Today, several methods are used to protect wood:
- The surface is coated with a special oil, which is then absorbed deep into the wood, preventing the wood fibers from swelling when exposed to moisture. Experts recommend using the following products for wood: OSMO TopOil, Belinda, Adler Lengo. To cover the countertop and protect it as much as possible, special oils are used along with wax compositions. But you need to remember that such protection periodically requires updating.
- Treat wood work surface special varnishes for wood products. You can add a coloring pigment to the composition to darken the deep wood fibers, while making the table plane more expressive. Coating a table with varnish is much easier than using oils and other products.
Main advantages of varnish
A varnished table will be more practical and will last much longer. After applying these paintwork materials, the aesthetic characteristics will significantly increase wooden furniture– textures will become more expressive, they will be better visible, and the color will become richer. Also, several layers of varnish will help prevent the destruction of the wood surface. The wooden table will be reliably protected from liquids, moisture, and mechanical influences.
Main types of wood varnish
In order for a wooden table to get a second life, you need to choose the right suitable material. Modern market offers a lot of options and the choice is very difficult. You should choose a product that will both improve aesthetic characteristics and reliably protect the surface from any negative influences. If even minor damage occurs on the surface, it long years will remind you of yourself, so you should approach your choice very seriously.
Alcohol based varnish
Alcohol-based varnish will create transparent or translucent coatings that will have a characteristic glossy sheen. At the same time, these materials provide the wooden surface reliable protection. If you do not violate the technology during application, then using products on alcohol based You can effectively highlight the beauty of natural wood.
These coatings contain resins dissolved in alcohols, which form a durable film. It is worth remembering that the stronger the alcohol, the stronger the film, and the most durable coating is formed when using a composition where the alcohol in the composition is stronger than 90%.
Oil varnishes
These are dissolved resins and pigments in oils. These products have a thick consistency and differ affordable price. After application, a sufficiently strong, resistant to various negative impacts film. This coating ideal for restoration work wooden furniture. These paintwork materials are especially effective if the table is under open air all year round.
It is important that a wooden surface that has been coated with oil varnishes will, after drying, receive a stable yellow tint that will not go away over time.
Nitrocellulose varnish
These are solutions of nitrocellulose in organic solvents. Despite their excellent performance characteristics, these materials are toxic, harmful to human health, and even after drying they have bad smell. The industry produces much less of these compounds and nitro varnishes are now being actively replaced by alcohol varnishes.
Water based varnish
With this composition you can get excellent, completely safe for humans, pets and environment coating. The composition is based on acrylates dissolved in water. After application to a wooden surface and drying, it becomes resistant to mechanical stress, moisture, and UV rays. protective layer.
Polyurethane varnishes
This option has high elasticity characteristics. The table covering perfectly withstands high mechanical loads, including impacts. These materials have a high drying rate. At the same time, the resistance to exposure to water and moisture is quite weak. The varnish is completely safe, the coating does not turn yellow, has a beautiful appearance and good transparency.
Among the advantages is that no preliminary priming is required.
How to restore a wooden table
Before varnishing dinner table or a work table in the kitchen, you should evaluate the condition very carefully. The surface may already be painted, mechanically processed, glossy, or varnished. Regardless of what varnish the surface will be coated with, it is necessary to carry out preparatory work.
In the video: how to cover a table with stain.
Preparation
The first step is to remove all the old coating. This is done so that the texture of the wood is clearly visible, using an electric tool. When the table is as smooth as possible, the surface does not have any defects, then you can move on to the next stage.
To work, you will need a roller or brush, and you will also need to purchase a remover liquid to remove the old paintwork. You will also need a primer and stain, a hair dryer, and sandpaper with varying degrees of grit.
Removing old coating
The chemical remover is applied to the table surface and then wiped off after 10 minutes. To apply and remove a layer of paint or varnish, use a rag.
There is also hot way– you need a hair dryer. The tabletop is heated and then wiped with a rag.
You can also remove the old coating by sanding. Doing this by hand takes a very long time, so it is better to use a power tool. The work is performed at low speeds so as not to damage the wood.
Varnish application technology
To apply varnish, it is better to use brushes or rollers. Using clear varnish to wooden table in one layer, it is very difficult to obtain the desired shade - this is only possible if you cover the surface in several layers.
A more saturated color can be achieved by treating the table with stain or colored primers - they are applied either in one layer, or in two, three or more.
After the stains and primers have dried, they can be varnished. The varnish is applied in a thin, even layer, trying to avoid drips. After the first layer has dried, it is recommended to sand the surface. For a high-quality result, varnish in three layers of varnish.
In a day old table turn into a new one and no one will ever be able to say that it is very old. Knowing how to cover a table, you can restore other wooden furniture in this way.
How to use wood varnish correctly (2 videos)
Everything you need to varnish a table (29 photos)
The kitchen is a place in the house where furniture is constantly in contact with water to a greater or lesser extent. Based on this fact, the question will be completely obvious: how to protect your favorite furniture set from moisture. After all, everyone knows the sad consequences of contact between water and chipboard (even waterproof): lumps, swelling, mold, and with a long “union” all this beauty, on which so much effort and money was spent, will simply rot.
So, let's identify the places most at risk:
- washing
- wardrobe with built-in drying
- plinth
- furniture above the stove and located in close proximity to it
- table top edges
Now let’s decide what measures need to be taken to protect your kitchen and enjoy its “marketable” appearance for many years.
Correct installation of sink and faucet
As for the sink, I would recommend not cutting the faucet directly into the countertop, as the faucet may start to leak. An exception, perhaps, can be made for small taps from filters with drinking water, since they are used less often, and the water pressure is not so powerful, the gasket will last much longer. However, if you decide to ignore my advice (there are different situations; IKEA, for example, sells sinks without holes for a faucet), be sure to treat the cut of the countertop! First, all dust must be thoroughly removed from the cut, and then it must be dried well with a hairdryer. Then apply a layer of diluted PVA glue, and after it dries, silicone. If it is possible for it to protrude, then it is better to choose transparent.
It is especially worthwhile to pay attention to the processing of the cut of the countertop when installing the sink. It also needs to be protected as much as possible from water. I must say that this is one of the most weak points any kitchen, unless, of course, your countertop is made of of stainless steel. So, just like when installing the faucet, you need to remove all dust from the cut, then dry it thoroughly with a hairdryer. Then apply a sealant; it is better to choose a silicone construction sealant, which is designed specifically for waterproofing seams. It is a waterproof, non-aging silicone mass. It is used to seal seams, cracks, seal windows and doors. It colors well. Such sealants can be white, gray or transparent. And here the most important rule comes in: DO NOT skimp on the sealant, this directly determines how long the countertop will last you. The inner radius of the seal, which is attached to the sink, should also be treated with silicone. Yes, and don’t forget to degrease the surface of the sink before gluing the seal.
People have several other ways to process sections: apply several layers of paraffin, PVA glue or varnish - until the tabletop stops absorbing more and more layers of the substance you have chosen. Some “craftsmen” cover the cut with self-adhesive film or wide tape. In any case, it’s up to you to decide which method to choose, but I would focus on progress.
If the countertop is swollen, then there is only one way to get rid of this flaw: replace it with a new one under warranty. That is why, if you bought a ready-made kitchen, use a service assembly. Otherwise, the company will disclaim all warranty liability.
Drying installation
To avoid water droplets getting on the chipboard in a drying cabinet, when purchasing the latter, you need to pay attention to whether a special tray is attached to it. If this is not observed, then it is better to refuse to purchase such drying, since water draining from the plates and falling to the bottom of the cabinet will inevitably cause its damage. In addition, it is necessary here good ventilation. This can be achieved either by installing “holey” facades, or by making a small hole at the top of the cabinet through hole, which can be given a noble appearance using a socket for wires (these are often used in the manufacture of computer desks).
Kitchen plinth protection
Use a plastic kitchen plinth. This element performs the function decorative design lower part kitchen furniture, closing the gap between the cabinet and the floor. Plastic plinths have a groove for fastening to the supports and a seal that protects against the ingress of water and dirt. The base has a number of advantageous characteristics: light weight, ease of installation, wide range of colors, aesthetic appearance, heights of 100, 120 and 150 mm, and is also completely resistant to moisture.
In the vast majority of cases kitchen countertops represent wooden surfaces, since wood is common and relatively affordable option. Environmental friendliness and good appearance are its advantages. But at the same time, we must not forget the susceptibility to destruction due to numerous external influences. However, this problem can be solved, since covering the countertop with protective components will help make the wood strong and durable, and will further improve its appearance.
- Wooden countertops, unlike plastic ones, are environmentally friendly;
- Unlike countertops made of natural stone, wooden analogues are cheaper;
- Naturalness in design. Attractive appearance;
- Ease of restoration.
Disadvantages of wood as a component of kitchen furniture
The kitchen is characterized by strong temperature changes and high humidity, which has a very serious effect on wood, in contrast to the same stone and especially high-quality plastic. At the same time, if we talk about the countertop, it is also necessary to note the impact of fats, detergents, knives and similar things found in the kitchen. The above-mentioned plastic and natural stone again win in this regard.
Finally, a quality work surface made from good breeds wood can be significantly more expensive than plastic, although cheaper than natural stone. Well, don’t forget the danger of fire.
Oil is the best way to protect wood
It doesn’t matter whether we are talking specifically about the countertop in the kitchen, or about other wooden furniture products, today varnish protection is practiced less and less. The reason is that the varnish is very non-ecological due to large quantity synthetic components. Well, in the case of this element of furniture, where food preparation takes place, the absence of harmful chemicals and naturalness is very important. Wherein varnished surface often scratched and needs updating.
Modern ones are free of all these disadvantages. oil compositions. By applying them to the sanded, untreated surface of the wood, we create a layer on it that has excellent resistance to water and other influences. At the same time, the texture of the wood does not change, and the oil itself does not have any unpleasant odors, unlike varnishes. It is worth noting here that there are both natural and synthetic oils, as well as mineral ones.
All wood oils are divided into two types - those that dry immediately and those that dry partially. The former themselves represent a very serious protection for wooden table top, creating a durable hard layer. The latter impregnate the wood to a certain depth. Wherein upper layer oils can be removed, and wax can be applied on top, for example.
What are the benefits of oil in protecting countertops?
- Complete safety in contact with food, which is important for the kitchen;
- Oils allow you to mask scratches and minor damage to wood;
- Resistance to high temperatures. Such oils do not separate and do not become liquid;
- When applied to old wood, the oil protects the latter from drying out and destruction;
- If you need to renew a damaged fragment, using oil can do this as simply as possible. This will not work with varnish;
- Oil-impregnated wood retains the possibility of natural moisture exchange, which prevents the appearance of fungus.
Process of oiling a wooden tabletop
Before starting work, you need to make sure that the wood is clean and free of old residues. paint coating. In this case, the surface must be carefully leveled and sanded. The recesses can be filled with putty.
Important! To apply a layer you must use a brush or soft cloth. The main thing is that the latter does not leave traces.
Working with a brush, it is enough to apply two layers. In the case of fabric, at least four are needed. When applying each subsequent layer, you must wait until the previous one dries. The process usually lasts 12 hours.
Painting a wooden tabletop
If oil, for one reason or another, does not suit you very much, then paint may be an option to solve the problem. In the event that we are talking about old board, then many of the actions here are repeated with those listed above. We also need to first remove old layers of varnish or paint, then clean the surface of dirt and dust, sand it and smooth out any unevenness, if any. After priming, several layers of alkyd paint are applied to the wood.
Tabletop film
There is another way to protect the wooden surface of the tabletop - by applying a self-adhesive film to it. This surface has a number of advantages:
- The film does not allow water to pass through and also withstands the effects of various liquids and household chemicals;
- Film designs are varied. The material can imitate various surfaces, or have a design or pattern;
- If you want to update your appearance, you can remove old film and install a new one.
As a disadvantage, we can remember that this element is still artificial, which neutralizes all the above-described advantages of wood. In addition, when applying the film you must be careful, since the slightest mistake can lead to the appearance of folds and other defects that spoil the appearance of the wood.
How to prevent damage to your countertop
Even taking into account the relative fragility of wood, its correct operation can significantly extend its lifespan and maintain its original appearance. All that is necessary for this is to follow a few simple rules.
Do not wash the surface of the countertop with aggressive agents not intended for this purpose. chemicals. Try to choose the right cleaning product and do not delay cleaning.
Despite the fact that the countertop is still a work surface, it is still better to use an appropriate cutting board. Cutting board It can be plastic or wooden. In the case of the latter, certain care is also required:
- To increase the protective qualities, as in the case of the countertop, wooden board for cutting, it can be coated with oil or antibacterial impregnation;
- A simple means of protection - ordinary sunflower or olive oil. To maintain the protective effect, it is recommended to apply at least once a month;
- Don't forget to wash your board thoroughly hot water after each use, and also dry it well. As a preventive measure, you can wipe the board with hydrogen peroxide or vinegar. If there is serious contamination, use detergents.
If you still can’t protect the tabletop
Most often, damage to wood appears in the form of chips or dents. In this case, the wood often rots, and these areas also need to be removed, which again leads to the formation of voids that need to be filled. In this case, you need to perform several actions:
- Thoroughly clean the surface of the wood and treat it sandpaper or a grinding machine;
- Place a mixture of sawdust and putty or polyvinyl acetate-based glue into the recesses. Then place it under a press and let it dry for several days;
- Before painting or otherwise treating the surface, it is important to give the sealed areas a smooth appearance.
The nuances of choosing a wooden countertop
So that all the above problems arise for you as rarely as possible, and carry out repair work was not required. When choosing a wooden work surface for the kitchen, you need to take into account a number of nuances.
Material. If we talk about wood, then the most the best options are oak, teak, walnut and beech and others. These breeds are strong and durable. But they are also the most expensive. If you choose other options, pine is the best. It contains resins that protect the wood from rotting.
Manufacturing method. Solid countertops (solid), which were mentioned above, are not affordable for everyone. Therefore, in the selection process, people often give options to glued models. The latter, especially if they consist of different types of wood, can combine strength, visual appeal and positive features of all types of wood that compose them. Veneer is a very thin covering of natural wood. In the case of the tabletop, he covers it with a slab of MDF or inexpensive types of wood. Finally, laminated options based on chipboard or MDF are very popular. They have a wide variety of appearances.
Natural wood in the kitchen? A wooden tabletop is one of the most good decisions for the kitchen, practical and convenient. You just need to know these 6 professional secrets.
Should there be a wooden countertop in the kitchen? We asked real professionals: qualified designers, craftsmen, technologists and wood specialists - those whose opinions you can trust.
1. Why is a wooden countertop not scary?
On the one hand, smooth warm wood with a beautiful natural structure- an excellent material for furniture production. Easy to use, environmentally friendly, always fashionable and relevant. Moreover, the tabletop is not a heavy wooden buffet that is impossible to move. You don't have to make all your furniture out of wood, which makes perfect sense. modern solution Only the table top and, perhaps, some other individual parts will be made from this material.
But many are afraid of how wood may behave, they are afraid of fungus, cracked varnish...
But professionals think differently: “A wooden countertop is not a problem if you apply reasonable, adequate care to it. There are not many materials used for countertops in non-professional kitchens that are not afraid of any impact and do not require maintenance - says Andrey Lyamin-Borodin, builder, CEO online repair ordering service PriceRemont. “All materials age during use, but the peculiarity of wood is that it can age gracefully.”
So what are we dealing with? Mikhail Vychuzhanin, wood finishing specialist, North House, defines the advantages and disadvantages of wooden countertops like this.
- environmental friendliness of the material;
- beauty and variety of wood texture;
- unlimited product parameters: almost anything can be made from wood in any way;
- easy to update;
- the ability to perform any milling of the edge of the tabletop.
- more careful care is required;
- restoration will be needed after some time;
- relative high cost of the material and work with it.
2. Which wood to choose for the countertop?
Here is the answer to the question of what types of wood and wood characteristics are worth paying attention to.
“When deciding on a wooden countertop in the kitchen, please forget about MDF, chipboard and veneer. Only natural wood, - advises Artyom Lepyoshkin, General Director of the Dynasty House of Interior Solutions. It's not a matter of harmfulness, but of the properties of the material. The countertop is exposed to aggressive human influence every day: crumbling, cutting, whisking, spilling and spilling are a common occurrence in the kitchen. The surface must be durable, smooth, resistant to cuts, moisture and temperatures.
The classic option is oak or beech: strong and durable wood species. Some choose teak and mebrow. More affordable options: pine, walnut, ash, birch. We prefer larch: you will have to pay more, but it will also last longer. The peculiarity of larch is very high density wood, growth rings are located along the trunk at small intervals. She tolerates it easily mechanical damage and deformation, withstands high compression and pressure loads. It contains gum - a natural antiseptic that protects against rotting and damage by mold. Ideal for the kitchen. Larch gives off and absorbs moisture when humidity changes.
The manufacturing method also affects durability. A solid wood tabletop is more likely to warp than a laminated wood tabletop assembled from several plates. This method increases flexibility and elasticity.”
“Attention should be paid to such points as: the age of the wood, the method of its extraction, storage conditions, the region where the material was brought from,” adds Mikhail Vychuzhanin. Most best breed He considers oak to be the wood used for making countertops. - The stronger and harder the wood, the longer your countertop will serve you. There are countertops made from solid birch, cherry, and walnut.”
3. How to cover a wooden countertop in the kitchen
The ideal option for protecting a wooden tabletop is bio-impregnation based on natural vegetable oils And beeswax- that is, oil-wax for wood. Natural oils for wood they can make its surface waterproof, which means that the wood is not afraid of fungus and mold. By the way, a tabletop impregnated with high-quality oil and wax becomes resistant to standard detergents for the kitchen - nothing bad will happen to wood from diluted household chemicals. It is even better and more reliable to treat the kitchen work surface with a special oil for wood that comes into contact with food. And of course, no one has canceled the more familiar coatings - interior varnish for wood or a combination of colored azure with subsequent application of varnish.
4. How practical is a wooden countertop?
How to protect wood besides using wood products?
If you want your countertop to last longer and maintain its appearance, follow simple rules: do not cut anything directly on the tree (perhaps only oak will endure such violence), do not test the surface for fire resistance and heat resistance. Very hot objects can darken wood, ash is especially sensitive. But if you spill wine or juice on the surface, just wipe it with a damp microfiber cloth. Do not use wet rags, this will cause the wood to swell.
We also do not recommend using aggressive household chemicals for washing the countertop. It happens that drops of such a product fall on the countertop when cleaning the sink or hob. If this product contains, for example, a solvent, it can change the color of the wood and whiten it. Important rule If any stains get on the countertop, do not allow them to be deeply absorbed, and therefore remove them immediately. A stain that cannot be washed off can be removed by walking over the area with fine-grained sandpaper, after which the protective coating will need to be renewed.
On the issue of choosing a sink - it is in in this case must be mortise or, in other words, invoice. Washing an under-table installation will create constant exposure to water on the edge of the tabletop, which will inevitably cause it to deteriorate. However, lovers of country style or owners of a tabletop made of particularly water-resistant wood may not be bothered by this.
5. Will this countertop suit my design?
Wooden surfaces in the kitchen also offer wide design possibilities and are a current trend. Here's what designers think about it.
The world is becoming more urbanized, and people are experiencing stress due to lack of communication with nature. Natural materials in the interior, such as wood, stone, clay help to modern man feel comfortable in the “concrete jungle”.
Since wood is not a moisture-resistant material, the part of the countertop adjacent to the sink can be replaced with an artificial stone surface.
Thus, a tabletop made of solid wood with knots, uneven texture, and aging effects suitable for the kitchen in rustic or loft style. But smooth wooden surfaces will look great in modern interiors, high-tech, especially tinted in white, black or graphite - such a tabletop will combine effectively with chrome and glass surfaces. It’s worth paying attention to options made from laminated wood - perhaps even from different types of wood: the rhythmic pattern of the elements can emphasize the beautiful geometry of the room.
This material is devoted to waterproofing the ends of laminated chipboards. To a greater extent, it is relevant for protecting the countertop from water, but when assembling furniture for the bathroom or kitchen, it would also be useful to treat the ends of the parts that make up the box.
As can be seen from the structure of the laminated chipboard, the part most exposed to moisture is the saw cut unprotected by the laminate. When water gets on it, sawdust swells and the part becomes deformed. I will say right away that moisture-resistant laminated chipboard (green polymer sawdust is visible on the cut) is not a panacea - for an experiment, throw a piece of such chipboard into a bucket of water... So for it, waterproofing issues are just as relevant, although to a lesser extent.
So, let's look at various protective techniques - their advantages and disadvantages.
1. Edge banding(often kitchen countertops are sealed at the edges with simple PVC or melamine). To be honest, this technique does not greatly protect the chipboard from swelling - water penetrates into the joint between the edge and the laminate and does its dirty work. Not suitable as a waterproofing agent(see photo 1).
2. -
due to the fact that the edging has overhangs that extend slightly onto the surface of the laminate, the joints, which were so defenseless in the previous version, become more closed, therefore provides better waterproofing. But isolated, that is, without the use of sealing compounds, its effectiveness is clearly insufficient.
3. Silicone sealant - can be used both in isolation and in
in combination with other techniques (processing the ends under edging or decorative end strips).
In addition, you can coat the ends of the laminated chipboard in the boxes with sealant in the places of the ties (those that are not covered with an edge); after tightening the joint, it is necessary to remove the squeezed out excess sealant with a rag - after the silicone dries, the box will be more airtight. Silicone should be used sanitary, that is, with protection against fungus. A “sausage” of sealant is squeezed out of the tube onto the end, and then smeared with a spatula or finger.
I would also like to note that the edge does not stick to silicone, and if it does, it doesn’t stick for long!
4. Treatment with Aquastop - An excellent alternative to sealant. Apply with a brush twice. After complete drying, it forms a layer on which you can even glue the edge (according to furniture makers - I haven’t tried it myself).
5. Paraffin treatment - this is old-fashioned, but nevertheless, extremely effective method waterproofing. The method looks like this: put the part on the end, stick it to the laminate on both sides masking tape(so that the end looks like it has sides), then take a candle and construction hairdryer melt the paraffin by pouring it into the resulting groove so that it spreads in an even layer over the surface of the end). And we continue to warm it up. In this case, paraffin will be absorbed into the chipboard like water. Processing is carried out at least twice. After this, we pour paraffin on the end, but do not fry it, so that it hardens, forming a protective layer. Excess is removed with a knife. A cross-section of the laminate shows that paraffin penetrates into the material to a depth of at least 3-4 mm, which provides excellent, but again not 100% waterproofing.
The main disadvantages of this technique are the labor intensity and, again, the impossibility of gluing the edges.
