Absorbent composition: types, properties and application

Wood at all times was a popular material, and today, despite the variety of different options, does not give up its position. To increase the period of operation and preserve the appearance, special coatings are used, which impart a gloss to the surface.

Description

The weaker composition not only improves the external characteristics, but also protects the structure from negative effects, including:

• Mold and fungal lesions;
• Temperature fluctuations;
• Exposure to ultraviolet rays;
• precipitation.

The composition of the coatings depends on the field of application, in this parameter they are divided into internal and external.

Exterior finish

For outdoor works, as a rule, materials that are based on various synthetic compounds, for example, alkyd-urethane and polyurethane, are used. They are characterized by high water-resistant characteristics, due to the presence of insoluble components. In addition to a high level of moisture resistance, the coating composition has a resistance to negative temperatures, direct sunlight and temperature changes. It should be noted that such facilities are not subject to established environmental safety requirements, so they are not recommended for use inside buildings. In this case, their use is limited to the corridor and the loggia, since for such premises as a bedroom, they are completely inappropriate.

Indoor application

For internal work, they are formulated on an oil and acrylic basis, they are safe for human health and do not have a sharp odor. In addition, acrylic products have many positive aspects:

• The drying speed of the layer is within 2-3 hours;
• The structure of wood is distinguished;
• There is the possibility of carrying out work on wet material;
• The tree retains the previous shade for a long time;
• No streaks are formed;
• Easier to care for the surface;
• Minimizes exposure to sunlight and moisture.

Some coatings have special components that provide antiseptic and fireproof properties.

Oil paints also have got enough distribution at the expense of firmness to mechanical influence and distinct steam-passing abilities, but their application is connected with long expectation of final drying.

What is a coating composition for plaster

This means, having a translucent and transparent structure, is used for tinting and coating plasters for interior work. They can have a different shape, for example, realized as a wax or varnish. Their use is not limited to decorative purposes, they form an additional protective layer on the surface and can act as an independent or finish coat.

Carrying out work

Before using the coating composition, it is necessary to carefully prepare the substrate to be treated.

If the surface is covered with paintwork, it must be removed with a spatula and a construction hair dryer. After that, the smallest residues are removed by sanding. In the presence of cracks and damages, before using the coating composition, they are sealed with a special putty. Then, grinding of the updated areas is carried out.

For the application of a coating coating, any conventional paintwork tools are suitable: it can be an airbrush, a roller or a brush. It is necessary that the temperature is at least 10 degrees. Also, painting can not be done on a too wet surface. It is necessary to pre-purchase special gloves, when using a spray gun a protective mask is added to them.

How a coating composition is applied

Dilute composition has better adhesion properties, so the material for the first layer is diluted with a solvent, oil or ordinary water, the choice of this or that option depends on the constituents.

On loose wood, after application of the first layer, fine fibers can rise and form an uneven rough surface. In this case, it is necessary to wait for drying and to treat the areas with fine-grained sandpaper.

Further, the spreading composition is distributed using any convenient tool. An additional layer may be required for a porous substrate, beforehand, a thorough grinding is performed. At the same time, observance of the established temperature regime is important not only in the course of work, but also within two to three days after staining.

Features

Many are interested in the question of how the coating composition is applied. At first glance, the process may seem simple, but to get a high-quality coverage you need to know all the subtleties. In the absence of haste and observance of the rules, the result will please both owners and guests, because such funds open up vast opportunities in creating an original interior. For example, they allow you to get soft color transitions on flat surfaces, and the pattern can consist of many shades. Various effects are created with the help of special tools, such as a spatula made of rubber, foam rubber and sea sponge, glove or coarse roller. Also, the coating composition is applied by the same sections equal to one square meter. To obtain an intensive shade, a multi-layer coating is used, while diffuse patterns are obtained by diluting the product with water.

Paints consist of many components: special additives, water and polyacrylate dispersion. Average consumption per 1 sq. Km. M is within 100 grams. It is possible to tint with various water pigments to obtain any desired shades using an automated and manual method. The optimum component ratio of the pigment and the coating is 1:10, respectively.

What you need to know

Regardless of the brand, for example, "Neomid" or "Olympus", the screed composition is optimal for different wooden surfaces: country furniture, doors, fences, windows, log fronts. The material not only provides a high degree of protection from the negative influence of the external environment, but also increases the decorative characteristics. Also, if you know all the stages of the work, the coloring can be applied even to a person who does not have the corresponding experience.

Packaging with the material should be in a cool, dry place, protected from sunlight, inaccessible to children and pets. If they get on the skin, they should be thoroughly rinsed under running water. Like all paint and varnish materials, the composition is decorative Is explosive.
