Wood requires special protection, in most cases it is enough to use paintwork materials to resolve this issue. For example, you can learn how to cover the tree stain. She will be able to penetrate the wood structure and protect wooden products from deformation, moisture and dirt.

To begin, you should explore the existing range of paints. We pay attention only to options for lumber.

Alcohol varnishes

A group of transparent and translucent coatings, with which you can make the surface shine, as well as protect it from external factors. They consist of complex components:

shellac;
sandals;
dug;
synthetic resin.

Carefully read the label with varnish, the strength of the alcohol used must be at least 90 ?. Ethanol can be used as a solvent.

Properly selected tool will allow you to select the structure and tone of wood.

Oil paints

Resins and pigments that are dissolved in oil are distinguished from the main components. The consistency can be liquid and semi-fluid, which allows you to apply it to the surface of the tree with a brush or roller. Affordable price is an attractive and positive factor for most people. After processing, a thin transparent film appears on the surface, which acts as a protective barrier for moisture and ultraviolet cure. Perhaps the manifestation of the characteristic yellow color.

The high degree of protection allows to coat with lacquers wooden products that are under the open sky.

Nitrocellulose varnishes

The basis includes nitrocellulose, which is diluted in organic solvents. The applied layer will dry for a long time, so you should take the object away from open windows and doors. The resulting hard coating will be resistant to both the sun's rays and mechanical loads.

During the work with this varnish it is necessary to worry about the protection: to put on a respirator, goggles and rubber gloves.

Water lacquers

Acrylate base in the aquatic environment - this is the composition of varnish. Before applying the water-based lacquer on a wooden surface, it must be thoroughly mixed or shaken. After complete drying, the varnish layer will protect the wood from water, solar radiation and mechanical loads.

Morilka

The process of staining is used to give the wood a certain color, in particular the color of a different wood species. The applied composition will penetrate into the structure without creating a film. This allows you to emphasize the structure and pattern of the tree and, in addition, to protect the wood. The main types of stains:

water based;
solvent based;
wax based;
alcohol based.

In a specialty store you can find such an assortment of stains: liquid concentrate, solution and powder.

Remove old layer

It is necessary to apply both a varnish, and wood stain exclusively on the prepared surface if it is a question of an old piece of furniture. Today, you can use three methods of cleaning wood from the old coating:

wash;
thermal effects;
mechanical effect.

To determine which method is suitable, it is necessary to individually, based on the type of product and paints and varnishes that were used before. Consider each method separately.

In the first case, the old varnish is removed with the help of special liquid solutions. It is applied with an ordinary paint brush to the surface, after which it is wrapped with plastic wrap to form a thermos effect. After a day with a spatula, the coating is removed, washed with water. The application of a new layer is possible after 24 hours.
The second method is faster, but for this you will need a building dryer. Armed with a simple trowel, you can begin the process: a small area is heated and gently removed the old coating.
The third option is suitable for processing a large area, such as a cabinet or floor. From special tools you will need a grinding machine, the remains are cleaned with sandpaper.

The composition of solvents in most cases includes toxic substances, so when working with them should wear a respirator.

Surface preparation

It is not enough just to remove the old layer, the surface needs additional processing, that is, grinding. Regardless of the new or old material in question, it must be carefully examined for defects. If seams, cracks and knots were found, they should be eliminated.

The gaps at the joints are sealed with a special wood putty. After drying, the irregularities are cleaned with fine-grained sandpaper. Raw wood does not need to be processed, since all actions will be meaningless: when dried, the tree is deformed, respectively, the applied layer is deformed too.

Application of stain

Due to the property of deep penetration of wood stain into the pores of wood, the solution enters into a chemical reaction with tannins, so that the product will be fully protected from fungi, mold and insects. To know how to apply the stain on a wooden surface, you need to familiarize yourself with the technologies and techniques.

Trituration. The stain is applied to a wooden surface, and then rubbed over the entire area. The result is a pronounced texture and natural pattern. The stains are especially good for porous wood species, for them are suitable compositions with a long drying time.
Spraying The hue of the stain is selected a few shades lighter than desired. Apply the liquid using the spray gun, with the result that you can get a perfectly flat surface.
Roller or tampon. As in the case of painting the surface with a roller, you need a special tray. A liquid stain is poured into it and then applied to the tree. No divorces or stains. This technique is especially popular when processing the floor. To make a tampon, you will need cotton and a clean cloth.
Brush. Simple and affordable technology for everyone. It should be noted that the coating in one layer will give a relatively deeper color than with other similar methods of application.

All the above tools for mowing down a tree are equivalent, therefore, when choosing, one can be guided solely by one’s own preferences. Processing technology is no different from the usual painting. But there is one important point: most of the stains dry very quickly, so work should be prompt and accurate. Do not allow the applied layer to dry before the work is completed, otherwise this area will differ from the rest of the surface.

It is necessary to apply wood stain parallel to the wood fibers, avoiding the contact of the layers.

As you can see, the process is quite simple. The number of applied layers depends on the desired shade. To fix the result of a wooden product or surface must be varnished.
