What varnish should I use on a wooden table? How to properly varnish wood: - DIY installation instructions, features of coating wooden products, tables, doors with stain, how to renew furniture, price, photo How to properly varnish new wood.

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 - 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 shapes, and ease of restoration. Along with the advantages, there are also disadvantages - wooden surfaces become dirty very quickly, the material is quite flammable, and is easily scratched due to even minor mechanical damage.

Also, the disadvantages include the high price of countertops 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 conditions of 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 wax compounds are used along with oils. But you need to remember that such protection periodically requires updating.

• Treat the wooden work surface with 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 of wooden furniture will significantly increase - the textures will become more expressive, they will be better visible, 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 material. The 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 will remain a reminder for many years, so the choice should be taken 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 reliable protection to the wooden surface. If you do not violate the technology during application, then using alcohol-based products you can effectively emphasize 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 are affordable. After application, a fairly durable film is formed on the surface, resistant to various negative influences. This coating is ideal for restoration work on wooden furniture. These paintwork materials are especially effective if the table is in the 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 an unpleasant odor. 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 an excellent coating that is completely safe for humans, pets and the environment. The composition is based on acrylates dissolved in water. After application to a wooden surface and drying, a protective layer is obtained that is resistant to mechanical stress, moisture, and UV rays.

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 you varnish your dining table or kitchen worktop, 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 a hot method - 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 a colorless varnish for a 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, the old table will 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 using this method.

Everything you need to varnish a table (29 photos)

You can restore the surface of an old wooden table using paints and varnishes, of which there is a wide variety on the construction market. Therefore, many consumers often have a question: What varnish should be applied to the dining table top to achieve the desired result? Properly selected material will not only improve the appearance of the furniture attribute, but will also create reliable surface protection.

Advantages of varnish

A tabletop treated with a special paint and varnish material will become practical and durable. After this processing:

• aesthetic indicators increase - the wood texture becomes expressive, clearly visible, and the color becomes more saturated;
• destruction of the wooden surface is prevented;
• additional protection against moisture is created;
• the wear process slows down.

Attention! It is very important not only to know what material to use, but also how the entire process of restoring the countertop goes.

How to restore a table from an array

Before applying a layer of varnish to the surface of the table, you should carefully inspect and determine its condition. The tabletop can be already painted, planed, glossy or varnished. The best thing for coating treatment is the absence of any decorative treatment. The entire restoration process will depend on the condition of the surface.

Preparing to apply varnish

First, you need to completely remove the old paint or varnish so that the wood texture is clearly visible. This can be done using a power tool and a special circle (disc) for wood. When the surface is perfectly smooth, polished and without the slightest defects, then you can begin applying the further processing process, and then apply the varnish.

What you need for work

• Brush or roller.
• Remover for old paint from wood.
• Stain.
• Primer.
• Grinder or grinder.
• Construction hair dryer.
• Sandpaper of different grain sizes, which is selected depending on the procedures being carried out: P12-P36 - coarse for removing old paint, P40-P60 - for rough cleaning the surface and smoothing out small irregularities, P150-P180 - sanding for painting, P240-P280 - sanding between varnish coatings, P400-P600 - final grinding of the surface for painting and polishing.
• Rags.

Technologies and removal of old layers of paint and varnish

The chemical flushing composition is applied to the work surface and wiped off after 10 minutes. A rag is used to apply the chemical composition and remove the layer.

The thermal method of removing old paint is done using a hair dryer. Under the influence of a hot air stream, the surface of the tabletop heats up well and is wiped with a rag.

The mechanical method involves the use of sandpaper of different grain sizes. But you can speed up the process using a grinder or grinder. Work should be performed at low speeds to avoid surface damage.

How and how to apply varnish to wood

To varnish the tabletop, you can use a brush or roller. Using a colorless composition at a time it is impossible to give the desired shade, only with repeated application. A stain of the desired shade or a colored primer, which is applied in one or more layers, will add richness to the wood. Depending on the brand of material, the time for complete drying varies, which determines the speed of application of subsequent layers.

Important! If stain is not used, then a primer must be used at least twice. This way, you can remove small irregularities on the surface and reduce varnish consumption.

What paint material can be used

• Natural varnish Biofa (Biofa) is a universal, colorless, intended for processing wooden interior elements. With its help, a durable, wear-resistant, breathable, water- and dirt-repellent layer is created. Suitable for primary processing and restoration of furniture, stairs and decorative items that are resistant to moisture. Complete drying time ranges from 16 to 24 hours. The color is tinted according to the catalogue.
• Varathane tinting polyurethane oil-based varnish - 2 in 1 (combines the properties of varnish and stain). Colors - Dark Walnut, Cabernet, Early American, Red Mahogany, Traditional Cherry, Provincial, Golden Walnut. The varnish creates a semi-gloss, glossy polyurethane protective coating that is highly wear-resistant. Excellent protection for solid furniture attributes.
• Polyurethane varnish from the Varathane collection series. The durable protective coating comes in semi-gloss, matte and glossy finishes. This tabletop is highly resistant to mechanical impacts of varying intensity. This is reliable protection that prevents fading and loss of color. After applying the first layer, the surface is sanded. Thanks to fast drying, the processing of the working coating is accelerated - up to 3 layers of varnish can be applied per day. The varnished surface does not lose its appearance over a long period and retains its shine and attractiveness.
• Organo-soluble polyurethane varnish is designed to create an even layer without flaws. It is also reliable protection for wooden surfaces from mechanical stress and fading. After applying varnish, the wood becomes fresh, its natural shade is restored, and its texture is emphasized. Ease of use lies in the fact that it dries quickly, which significantly reduces the processing time of the coating. In addition, the varnish has self-leveling properties.

We restore or restore the dining table top using paints and varnishes. If you consider how much new furniture costs, this is not an expensive technology at all. Knowing how to restore a wooden surface, your furniture will take on a renewed look and last a very long time.

How to properly varnish wood: choosing materials. Drying time, water-based varnish application technology. Using varnish in combination with stain

Coating wooden products with varnish is one of the most common methods of decorative processing of painted and unpainted surfaces. The use of varnishes is a universal finishing method, as it is suitable for most types of wood, regardless of the density of the materials and their texture. This finishing method is widely used in the manufacture of furniture, in the finishing of buildings made from lumber, etc.

When planning to purchase varnish to coat wood, you need to understand that the quality of the finished result largely depends on a number of conditions, including: the degree of preparation of the surface, the correct selection of varnish in accordance with the type of wood, and compliance with the technology for applying paints and varnishes.

In this article we will talk about the features of choosing and using varnishes in combination with the use of pigmenting compositions for wooden surfaces.

LMB selection

An example of how to varnish a wooden door using a brush

There is a wide range of paint and varnish materials on sale, but not all of them are intended for processing lumber.

The following types of paints and varnishes are used for application to wooden surfaces:

• Alcohol varnishes are transparent and translucent coatings that add shine and protect the rough surface from the negative effects of environmental factors. The right coating, when applied correctly, can highlight the texture of the fibers and enhance the tone of the wood, which guarantees obvious advantages when finishing furniture.

The photo shows an example of how to coat a wooden table with alcohol-based varnish

Alcohol-based varnishes are complex solutions containing film-forming substances such as shellac, sandarac, copal or synthetic resins. Ethyl alcohol is used as a solvent.

A separate type of alcohol-based paints and varnishes is polish. Such compositions contain about 30% shellac resins and 70% ethyl alcohol.

Important: In order for alcohol varnishes to form a sufficiently durable coating, the strength of the alcohol used must be at least 90°.

• Oil varnishes. The price of which is low, they are complex compositions consisting of a certain amount of resins and pigments mixed in oil.
  The finished varnish has a liquid or semi-liquid consistency, and therefore can be applied with a brush or roller. After application, the solution dries, forming a transparent film on the surface that is resistant to precipitation and mechanical stress. Therefore, oil-based varnishes for impregnating wood are an excellent means for finishing country furniture, which spends most of its time outdoors.

Important: Most oil-based varnishes have a characteristic yellowish tint that does not disappear after the applied layer has completely dried.

• Nitrocellulose varnishes (nitrovarnishes) are compositions prepared on the basis of nitrocellulose diluted in organic solvents.

Important: Considering the toxicity of fumes when nitro varnishes dry, during their use it is necessary to use a respirator and work in well-ventilated areas.

Spraying varnish using a spray bottle

Nitrovarnishes, regardless of how they are applied, form a smooth and hard coating that is resistant to UV radiation and mechanical stress. Nitrocellulose-based coatings take a long time to dry; in order to speed up the drying process, the content of organic solvents in the composition increases.

Due to the toxicity of organic solvents, the share of production of nitro varnishes is decreasing everywhere in comparison with the volume of production of similar alcohol- and water-based compositions.

• Water-based varnishes are compositions made using an acrylate base mixed in an aqueous environment. The finely dispersed acrylate base does not dissolve in water, but is suspended particles. Therefore, the product is thoroughly mixed before use.

In the photo you can see how to update varnished wooden furniture

Once applied to the wood, the varnish layer dries to form a dense, hard coating. After complete drying, the finishing layer demonstrates resistance to water, UV radiation and mechanical stress.

Water-based varnishes are widely used in the modern furniture industry, as well as in finishing the interior and exterior of construction projects built from lumber. A significant advantage of water-based varnishes is their environmental safety, and therefore finishing work can be carried out without a respirator.

So, we have looked at the main types of paints and varnishes suitable for processing lumber, and you can decide which varnish to coat a wooden door or other wooden surfaces with.

Drying time

Refinishing old faded furniture

In order to know exactly what varnish to coat a wooden table with, you need to have a general idea of ​​the drying rate. You can see these parameters in the following table.

Water-based varnish application technology

Professional door decoration

After we decided on the choice of product, it remains to figure out how to properly varnish the wood. As an example, let's look at the features of using water-based acrylic paints and varnishes.

The instructions for finishing work are as follows:

• At the initial stage, preparatory work is carried out, during which the surface is brought into an optimal state for applying paint and varnish.
  First, the surface is sanded to remove roughness and dirt, then the products treated in this way are brushed to remove dirt and dust.
  If there are areas affected by mold on the surface of the wood, it is necessary to use special bleaches and conventional antiseptic solutions. After completing the preparatory work, it is necessary to keep the product indoors so that the humidity level is no more than 10%.
• At the next stage, thoroughly mix the varnish, bringing its consistency to a homogeneous consistency.

Important: All subsequent work must be carried out at an air temperature of at least +10 °C.

• Apply wood varnish using a brush or roller. We move the tool along the direction of the fibers in order to emphasize their texture.
  After one coat has been applied, wait the time required for it to dry to touch. Then we inspect the surface for uniformity of coating.
  If the layer is unevenly absorbed into the wood, wait until it dries completely, after which we apply the varnish again in a thin layer. When treating wooden furniture with paint, it is allowed to apply paintwork in several layers until the optimal appearance of the coating is obtained.

Important: If finishing work is carried out on surfaces with a large area, the applied composition should be diluted to obtain a more liquid consistency and used in combination with a spray gun.

Using varnish in combination with stain

Applying stain with a cloth swab

Coating wood with stain and varnish is a unique opportunity to give ordinary lumber the appearance of rare and, as a result, expensive wood species. The choice of stain depends on the type of varnish used.

As an example, let's consider the technology of applying a one-component water-based stain followed by applying a water-based varnish. The choice of finishing materials is not accidental, since water-based compositions are easy to use and can be applied with your own hands using a regular brush.

Applying stain along wood fibers

The instructions on how to properly coat wood with stain and varnish are simple. Dip the brush into the stain and apply it to the previously prepared surface along the grain. When applying the composition, rub it thoroughly with a brush so that it penetrates into all the recesses.

The stain, when absorbed into the wood, will give an uneven shade: between the fibers it will be lighter, and at the tops of the fibers it will be darker. This is due to the different densities of wood.

In order to even out the shade, you can apply a second layer of stain. But, if you want the texture to be visible, it is better to do with one layer. After the stain has completely absorbed and dried, you can apply varnish.

The choice of furniture in modern furniture stores is quite wide, as is the material from which it is made. But products made from natural wood have not lost their attractiveness. For example, a kitchen set made of solid wood. Such a product will be 2-3 times cheaper if you order it from a craftsman. You can try to assemble it yourself, even better. That parts for such furniture are also widely available in stores. But, we will talk about what kind of varnish to cover a wooden table so that the furniture is protected from all kinds of damage and is pleasing to the eye.

Varnish selection

Preferences in choosing a paint material depend only on consumers. Our task is to familiarize them with the properties of each type. Varnishes for table coverings are:

• Water-based are the most environmentally friendly. The substance is almost odorless and does not pose a health hazard to the consumer. Water-based varnishes are most often used for children's furniture. But professional craftsmen rarely use them, since after drying the treated surface becomes matte.
• Acrylic-based materials are affordable and quite easy to process. It is best for beginning craftsmen to start with these varnishes. If mistakes are made during the work process, they can be easily corrected. To do this, use white spirit or grind the surface.
• Polyurethane based and recommended for professional craftsmen. It is better to apply this substance by spray. In this case, the surface will look quite stylish. It is better to purchase such material in branded stores.
• For very expensive wood, specialized furniture oils are used. This composition is quite expensive, so it is rarely used. Apply only by hand using a swab.

For beginning craftsmen, a very important question is what shade to choose varnish for a wooden table. The customer must also put an end to this issue. You can not disturb the natural texture of the wood or cover it in the color of cherry or walnut. But you don’t always get the result you expect. To prevent this, you should familiarize yourself with some features:

• Colorless varnish will not always preserve the original appearance of wood. Most often it gives the wooden surface a yellowish appearance. Therefore, if it is necessary to maintain the original shade, it is better to use polyurethane materials. They eliminate the appearance of yellowness.
• When visiting branded stores, sellers will provide a large assortment of colors to choose from. To get the color that you prefer, it is better to take a color that is 2-3 tones lighter. After all, the desired gloss on a wooden surface is formed only after applying 5 or 6 layers. With each subsequent layer, the shade will become darker.
• In the case when 2-3 layers are applied and the result is the desired surface color, but the required gloss is achieved, then this problem can be solved with the help of colorless varnish.
• Varnishing should begin only after high-quality sanding has been completed.

Technology of varnishing a wooden table

Before starting work, you should figure out how to varnish a wooden table. First you should worry about how to protect your respiratory system. To do this, you need a dust respirator or mask. Also, work is carried out only in rooms that are well ventilated. To varnish a table correctly, we present some algorithm.

Preparing the surface

Surface preparation plays a very significant role in the quality of varnishing a wooden table. First, you should stock up on tools for sanding a wooden surface:

• sandpaper of varying degrees of grain;
• a piece of wooden block;
• a piece of rubber;
• long stick.

The wooden block must be wrapped with sandpaper and secured. This method will greatly facilitate the work and help make the surface perfectly clean. Using a block with sandpaper, smooth surfaces are processed.

If you need to process rounded surfaces, it is better to use a piece of compacted rubber and also wrap it with sandpaper. The holes are processed with a stick and sanding paper.

Correct processing is achieved by smooth movements along the grain of the wood. This method will prevent the formation of scratches on the table surface. You need to start with coarse sandpaper and gradually reduce the grit until you get to the minimum grit.

If scratches do form, the area must be moistened, allowed to dry, and then the sanding process repeated with fine-grained sandpaper.

Priming process

Before varnishing the table, the wooden surface should be primed. It is the primer that will close the pores in the wood and much less varnish will be required. The following compositions are used for priming a wooden surface:

• liquid wax;
• turpentine to which wax is added;
• a mixture of PVA glue and wood powder;
• a solution of wood glue and water.

The primer is applied to the surface using an aerosol can or brush. Then leave it to dry for a while and re-treat it with fine-grained sandpaper.

Important: before applying varnish to the table surface, thoroughly remove all dust.

Applying varnish

Painting a table with varnish consists of the following steps:

• Cover the table with stain in a small amount. At the same time, we do not allow the formation of greasy strokes and drips. After application, wait for the stain to dry completely.
• The second layer is applied after the one already applied has stopped sticking. Sometimes you have to apply several layers of stain. To give the surface a glossy finish, it is sometimes necessary to perform intermediate sanding.
• After the required shade has been achieved, they begin to open the surface with colorless varnish. The varnish should also be applied evenly, without smears or drips.

By following all the rules given in this article, novice craftsmen will be able to do their work easily and quickly. Read more about other options
