Wood has always been a popular material, and today, despite the variety of different options, it does not give up its position. To increase the period of operation and preserve the appearance, special coatings are used to add gloss to the surface.
Description
The glazing composition not only improves the external characteristics, but also protects the structure from negative influences, which include:
- mold and fungal infections;
- temperature fluctuations;
- exposure to ultraviolet rays;
- precipitation.
The composition of the coatings depends on the application, for this parameter they are divided into internal and external.
Exterior finish
For outdoor work, as a rule, materials are used that are based on various synthetic compounds, for example, alkyd-urethane and polyurethane. They are distinguished by high waterproof characteristics, due to the presence of insoluble components. In addition to a high level of moisture resistance, the glazing composition is resistant to negative temperatures, direct sunlight and temperature extremes. It is worth noting that such means do not have established environmental safety requirements, so they are not recommended for use inside buildings. In this case, their use is limited to a corridor and a loggia, since they are completely unsuitable for rooms such as a bedroom.
Indoor application
For internal work, compounds based on oil and acrylic are used, they are safe for human health and do not have a pungent odor. In addition, acrylic products have many positive aspects:
- the drying speed of the layer is within 2-3 hours;
- wood structure stands out;
- there is the possibility of carrying out work on wet material;
- the tree for a long time retains its former shade;
- streaks do not form;
- surface care is simplified;
- exposure to sunlight and moisture is minimized.
Some coatings have special components that provide antiseptic and flame retardant properties.
Oil paints have also gained sufficient distribution due to resistance to mechanical stress and distinctive vapor permeability, but their use is associated with a long wait for the final drying.
What is a glaze plaster
These products, which have a translucent and transparent structure, are used for tinting and coating plasters for interior use. They can have a different shape, for example, realized in the form of 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 coating.
Work
Before using a glazing composition, it is necessary to carefully prepare the processed base.
If the surface is covered with paintwork, it must be removed with a spatula and a building hair dryer. After that, the smallest residues are removed by sanding. In the presence of cracks and damage, before using the glazing composition, they are sealed with special putty. Then, grinding of the updated areas is carried out.
Any conventional tools for paintwork are suitable for applying a glaze coating: it can be a spray gun, a roller or a brush. It is necessary that the temperature be at least 10 degrees. Also, painting can not be done on a wet surface. You must first purchase special gloves, when using a spray gun, a protective mask is added to them.
How to apply a glazing composition
The diluted composition has the best adhesion properties, so the material for the first layer is diluted with solvent, oil or ordinary water, the choice of one or another option depends on the constituent components.
On loose wood, after applying the first layer, small fibers can rise and form an uneven rough surface. In this case, it is necessary to wait for drying and treat the areas with a fine-grained sandpaper.
Next, a glazing composition is distributed using any convenient tool. An additional layer may be required for a porous base, thorough grinding is preliminarily performed. At the same time, compliance with the established temperature regime is important not only during the work, but also within two to three days after staining.
Features
Many are interested in the question of how to apply a glazing composition. At first glance, the process may seem simple, but knowledge of all the subtleties is necessary to obtain a high-quality coating. In the absence of rush and compliance with the rules, the result will please both the hosts and guests, because such tools open up vast opportunities in creating the original interior. For example, they allow you to get soft color transitions on smooth surfaces, while the picture may consist of many shades. Various effects are created using special tools, including a rubber spatula, a foam sponge and a sea sponge, a mitten or a rough roller. Also, the glazing composition is applied in the same areas equal to one square meter. To obtain an intense shade, a multilayer coating is used, while blurry patterns are obtained by diluting the product with water.
Paints consist of many components: special additives, water and polyacrylate dispersion. Average consumption per 1 square. 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 optimal component ratio of pigment to glaze coating is 1:10, respectively.
What you need to know
Regardless of the brand, for example, “Neomid” or “Olympus”, the glazing composition is optimally suited for various wooden surfaces: country furniture, doors, fences, windows, log facades. The material not only provides a high degree of protection against the negative influence of the external environment, but also increases the decorative characteristics. Also, with knowledge of all stages of work, painting is within the power of even a person who does not have the appropriate experience.
The packaging with the material should be in a cool, dry place, protected from sunlight, out of the reach of children and pets. If it comes into contact with the skin, they must be thoroughly rinsed under running water. Like all paints and varnishes, the composition is decorative glaze is explosive.
