Acrylic varnish for wood is often used for interior work. Its inconvenience for external use is due to the specifics of the composition, however, types for external decoration still exist. The scope of use and features of this varnish should be considered in more detail.

Peculiarities

Acrylic varnish contains dispersion and other substances that allow not only treating wood with an even layer, but also protecting it from some harmful effects. This refers not only to the consequences of the vital activity of microorganisms, but also all kinds of climatic influences: increased dryness or humidity, for example. By itself, such a varnish has the texture of thick sour cream, but it is more viscous. The classic color is delicate milky.

The tool has many advantages, including the following

• Safety . There are no toxic elements in the composition of acrylic varnishes. Some of them can even paint dishes.
• Durability . High-quality varnishes do not wear off much over time, reliably protecting wooden surfaces for many years.
• Ecological cleanliness . Not to say that all the elements that make up the varnish are natural, but it decomposes and at the same time does not harm the environment.
• Practical convenience . It is easy to care for varnished surfaces, especially if they have increased strength characteristics.

• High functionality . Varnishes are used for various coatings on wood, from painting tableware elements to finishing terraces and gazebos.
• Aesthetic appeal . Wood covered with acrylic paints and varnishes looks presentable. Its color and texture deepens, the texture appears more clearly
• Ergonomic This refers to the achievement of optimal performance with low material consumption. For example, applying only two layers, you can limit yourself to only them, since the tree will already look good.

• High elasticity . When solidified, the varnish forms a protective film, which cannot be removed in the future.
• High strength characteristics . Even at a high level of stress, the lacquer coating will never completely wear off.
• High adhesive properties . The varnish has good adhesion to the original surface, as a result of which such a high strength is achieved.

• Subtle smell . Many consumers note the presence of a faint smell, similar to that which is emitted by ordinary gouache. Epoxy and other paints and varnishes are in no way comparable.
• Short period of time required for setting and drying. As a rule, multiple coats can be applied within one daylight hours.
• Resistance to the vital activity of microorganisms . Acrylic varnishes clog the surface of the wood, preventing plant spores or bacteria from entering.

• Resistance to adverse climatic events . This also refers to the microclimate of the room. For example, lacquer material is able to protect wood from cracking in a room with dry warm air.
• Affordable cost . The price of acrylic paints and varnishes cannot be called excessively high, rather, it is at an average level.
• Ease of operation . Several tools are suitable for application at once: the varnish is not very capricious in this regard.

In addition to the advantages, the material also has some disadvantages

• The need for a special temperature and climatic conditions during application. Do not apply varnish if the temperature is below +5 degrees or above +30 degrees. The technology will be violated, and the paintwork will not be guaranteed to be durable. Drafts should also be avoided.
• The need for special storage. Do not freeze or even cool the material, expose it to sunlight.

Views

Initially, all acrylic varnishes are divided into two large groups: one-component and two-component. The one-component varieties contain only acrylic; two-component are also characterized by the presence of polyurethane.

It should be noted that two-component varnishes guarantee higher durability .therefore they are most often chosen for external work.

The most popular are water-based acrylic varnishes. They are increasingly replacing conventional furniture varnishes. Acrylic scuba diving has become so popular because compared to other products that are also water-based (alkyd, for example), they are cheaper.

The reverse side of the coin is strength characteristics . They cannot be called elevated. As a consequence, such varnishes are not used outdoors. They are suitable only for painting floors and furniture, while it is important to comply with all requirements regarding the working conditions with paint and varnish materials indicated on the packaging. Usually refers to temperature and humidity.

Two-component acrylic-polyurethane varieties, despite almost the same price, have higher strength properties than their one-component equivalent. However, you should not use this variety outside the room: it will not work for outdoor work.

Acrylate varnishes, also related to acrylic, have a slightly expanded area of application . So, with their help, you can not only tint and give a glossy shine to clean wooden surfaces, but also apply them to already painted elements. It is important to keep one thing in mind here. The paint used for painting must also be water-dispersion, otherwise the varnish will not set properly.

There are few types of acrylic varnishes, but each of them is universal. If necessary, you can use each of them for outdoor decoration, but only on condition that you live in a temperate climatic zone without extreme weather conditions. Otherwise, the paint and varnish material will not withstand and will simply crack, having lost the lion's share of its operational properties.

Colors

Initially, acrylic varnish for wood is produced in a milky white color, but when it dries, it forms a colorless film that only emphasizes the texture of the wood without giving it any special shade. The transparent film only adds shine, due to which the original tone of the wood appears deeper and richer.

In recent years, new production and tinting technologies have appeared, which have significantly expanded the color range of varnishes. Now you can easily purchase a tinted acrylic sample, which can successfully replace the stain. So you can solve two problems at once, without resorting to complicated procedures: to give the boards the desired color and to protect them.

According to the level of gloss, five degrees are distinguished, each of which is characterized by the amount of light reflected in percentage by the surface covered with such varnish:

• high gloss - more than 90%;
• glossy - 80-90%;
• semi-glossy - 40-50%;
• semi-matte - 10-15%;
• matte - less than 10%.

When choosing, it is worth keeping in mind the features of shiny coatings. On glossy surfaces, all the flaws stand out strongly. Moreover, it is more often used to decorate modern interiors in hi-tech, futurism and the like. Matte varnish, on the contrary, allows you to partially hide blemishes, and the surface is velvety. Such an effect is needed when creating an atmosphere of comfort, for example, in the styles of Provence, country and others.

When choosing a varnish, decide what effect you want to achieve in the end . You may just need to emphasize the beauty of the wood or slightly change its shade, give the wood a shine or pearl shine. Remember that if you don’t like the way this or that varnish lays down, you can partially dismantle the acrylic film by “walking” over the surface with a grinder with a special grinding disc. However, care must be taken to ensure that the removal is the same throughout the entire area.

Selection and application

Acrylic varnish is applied in several layers.

Several tools can be used for application:

• Roller with pile length up to 5 mm. Ensures fast staining.
• Brush. The work is more laborious, but it is possible to decorate all hard-to-reach places.
• Spray gun or spray. The most convenient and economical application method. Allows you to apply an even layer, including on hard-to-reach places.

The choice of this or that material is half the battle. Make no mistake. So, if you plan to cover, for example, a chest of drawers with an abundance of carved parts, then it is best to use a spray gun. A roller is also suitable for even plank floors.

Before starting work, you need to complete the preparation . The surface must be cleaned, in some cases a primer is needed. If possible, refuse to purchase an acrylic sample that is superimposed on a primer. Then the original texture of the wood will be pronounced.

Few varnish can guarantee a protective finish after one coat, so they are applied in at least two. To make the coating even, you need to sand the first layer after it dries. After cleaning the surface, you can apply a second layer.

After all the work on the application of the varnish layer is completed and the coating is dry, you can proceed to finishing. Keep in mind that acrylic varnish dries completely in two days. For this, it is best to use parquet care products or wood wax. Such procedures will save the varnish coating from quick deterioration, because it will pick up its final performance characteristics only after two weeks.

Tips

Finishing professionals share some recommendations regarding the choice of acrylic lacquer, its use, operation and storage.

• It so happens that the varnish thickens over time, and it needs to be diluted. Under no circumstances should solvents or other chemicals be used for these purposes. Only clean water will do.
• When diluting, you need to remember the proportions. If you add more than a tenth of water to the composition, this will lead to the loss of its properties and rapid deterioration of the wood after processing.
• Before using the paint and varnish material, it must be thoroughly stirred in order to exclude the possibility of streaks and color spots on the surface.
• Before processing, you need to check the moisture content of the wood. Ideally, it should be well dried, but it is permissible to varnish the boards if their moisture content does not exceed 50%.

• Degrease the surface thoroughly. In places with greasy stains, the varnish simply does not adhere to the surface, and this will lead to defects. In addition, when a milky substance is applied to such places, its color will not disappear, but will remain the same, which will be very noticeable.
• Follow the instructions. It will probably say there that you do not need to make one thick layer of material. It is best to overlay a pair of thin ones.
