It is necessary for you to know about texture paint.

Latex paint is our most common wall decoration material. There are many kinds of latex paints in the building materials market. Different types of latex paints can bring us different decorative effects. Today we will talk about the texture paint in latex paint. You need to know this knowledge.

Texture is an important visual element to present the texture, shape and rendered shape of an object.

In many cases, it is used as a means to deal with the material of the design object, to reflect the quality of the design object and the style of the material, as a specific style accepted by people and a factor to become fashionable.

The concept of texture, as a positioning of natural object observation method, will strengthen the understanding of object matrix. It tempts people to experience and touch with vision or mind, and objects and vision produce intimacy and visual pleasure. Observing the texture helps us to know, understand, express and recreate the form, and helps us to deeply understand the meaning and function of formal language.

Construction requirements of textured coatings:

1, concrete or plaster base besmear brushs solvent-based coating, the moisture content shall not be greater than 8%; When painting water-based paint, the moisture content shall not be greater than10%; The moisture content of wooden base shall not be greater than 12%.

2, the construction site environment temperature should be between 5 ~ 35℃, and should pay attention to ventilation and dust prevention.

A, texture coating base treatment shall meet the following requirements:

1. Concrete and cement mortar plastering base: smooth and polished with putty, with smooth and straight surface.

2. Gypsum board base: After the board joints and nail holes are treated according to the design requirements, they should be fully putty-blown and polished.

3. Lacquer wood base: the surface should be smooth, the color should be consistent, and the surface should be free of pollution, cracks and defects.

4. Basic requirements of ready mixed paint: The surface should be smooth and free from serious pollution.

5. Metal base: the surface should be rust-proof and rust-proof.

Second, the general method of texture coating construction:

1. Roll coating method: firstly, move the wool roller dipped in paint in W mode, and roughly coat the paint on the base; then, roll the wool roller dipped in paint close to the base, up and down, left and right, so as to evenly coat the paint on the base; finally, fully roll the wool roller dipped in paint in a certain direction. Internal corners and upper and lower mouths should be brushed with a brush.

2. Spraying method: the pressure of spray gun should be controlled within the range of 0.4 ~ 0.8 MPa. When spraying, the spray gun should be perpendicular to the wall, the distance should be about 500mm, and the spray gun should move in parallel at a uniform speed. The overlapping width of two lines should be controlled at 1/3 of the spraying width.

3. Brush coating method: it is carried out in the order of left and right, up and down, easy and difficult, and edge and back first.

Third, the texture lacquer wood-based paint varnish:

The scab and turpentine on the essence base should be sealed with shellac paint, and the nail holes should be oily. Before scraping putty and coloring, you should brush the sealing primer once, and then repeat local color matching and color matching. After each repair, the intermediate paint should be brushed, dried and polished until the color tone is harmonious and unified, and then the top paint decoration should be carried out.

Four, wooden base besmear brushs ready mixed paint:

After drying, brush nail holes, cracks and defects with grease. After it is dried, it is polished smooth, and then the middle and surface paints are brushed.

Five, pan-alkali, salting-out base should be cleaned with 3% oxalic acid solution, and then rinse with water or brush alkali-resistant primer on the base, and then brush the top coat after drying.

VI. Textural coating The intermediate coating of the relief coating should have uniform particles, and roll evenly with a special plastic roller dipped in kerosene or water. After being completely dried and solidified, the surface coating can be carried out, and the surface coating should be sprayed and the solvent-based coating should be brushed. The interval should be greater than 4h.

Seven, texture paint construction need to pay attention to what?

1. Construction environment: If the solvent-based coating is directly applied to the concrete surface, pay attention to that the water content of the wall must be below 8%; If water-based coatings are used, the water content must be below 10% to ensure that the final effect will not be affected.

2. Base treatment: If it is a concrete base, it needs to be scraped first, and then polished to be smooth, so that the pattern will be more beautiful. If it is a gypsum board base, cracks and nail holes need to be treated first, and then scraped and polished.

3. Environmental performance: At present, there are many kinds and brands of textured coatings on the market. In order to ensure the quality and effect of decoration, we should pay attention to the choice of good quality. If the conditions are not clear, it is recommended to choose a well-known brand, which will ensure the quality and after-sales service.

4. Construction technology: The effect of textured paint seems simple, but it actually requires high construction technology, especially for making special patterns, you must choose experienced masters, otherwise the final effect may not be satisfactory.

Texture paint can bring us a good texture in decoration. The construction requirements, methods and precautions of textured coatings are introduced above. We should carry out construction according to these requirements and methods when decorating textured coatings, and master the matters needing attention in construction to make the construction effect of textured coatings better.
