Everyone knows that exterior paint's concept can be divided into two categories: water-based and milk-based. Exterior paint also plays an outstanding role, but when it is used outdoors and indoors, the amount of formaldehyde preservative added is also different.

Exterior wall decoration is directly exposed to nature, subjected to wind, rain and sun, so the coating is required to have water resistance, color retention, pollution resistance, aging resistance and good adhesion, as well as good freeze-thaw resistance and low film forming temperature. ? Exterior wall coatings are divided into four categories according to decorative textures:

1. Thin exterior wall coating: fine texture, material saving, and can also be used for interior wall decoration, including plane coating, sand wall coating and mica coating.

Characteristics of exterior wall coatings:

1, good decoration: the exterior wall coating is required to be rich in color and excellent in color retention, and can maintain the original decorative performance for a long time.

2. Good weather resistance: When the coating is exposed to the atmosphere, it will be affected by wind, sunlight, salt spray corrosion, rain, cold and hot changes and so on. Under the long-term repeated action of these external natural environments, the coating is easy to crack, powder, peel and change color, which makes the coating lose its original decorative and protective function. Therefore, it is required that the coating of the external wall will not be damaged within the specified service life.

3. Good stain resistance: Due to the great differences in environmental conditions in different regions of China, for some cities with developed heavy industries and mining industries, due to the large amount of suspended solids such as dust in the atmosphere, the paint that is easy to stain will lose its original decorative effect, thus affecting the appearance of buildings. Therefore, the exterior wall coating should have good stain resistance, so that the coating is not easy to be polluted or easy to clean after pollution.

4. Good water resistance: the exterior wall paint facing is exposed to the atmosphere and is often washed away by rain. Therefore, exterior wall coatings should have good water resistance.

5. Good mildew resistance: the exterior wall paint facing is easy to mildew in a humid environment. Therefore, coatings are needed to inhibit the propagation and growth of molds and algae.

Disadvantages of exterior wall coatings:

Poor texture and short service life. Even the paint with a service life of 10 years may need to be cleaned and repainted in less than 5 years, and this cost still needs to be paid by the owner, usually from the house maintenance fund paid by the owner.

In addition, the shrinkage of exterior wall coating after cement solidification will produce some cracks on the facade. Although the new elastic paint can solve this problem, the price of elastic paint is also relatively expensive. It is recommended to use good tiles.

The main function of exterior wall paint is to decorate and protect the exterior wall of the building, so that the appearance of the building is beautiful and tidy, thus achieving the purpose of beautifying the urban environment. At the same time, the exterior wall coating can also protect the exterior wall of the building and prolong its service life.
