Is it necessary to carry out anti-alkali primer treatment before spraying real stone paint?

1. What is real stone paint?

Real stone paint is a special paint that creates textures similar to marble, granite, wood grain and other stone materials on the surface of buildings. Suitable for painting indoor and outdoor walls, ceilings, floors and other decorative surfaces. The main components of real stone paint are resin, pigments and fillers. Its service life and effectiveness depend on the quality and stability of the paint surface.

2. Why is it necessary to carry out alkali-resistant primer treatment?

The construction of real stone paint requires the use of alkali-resistant primer for basic treatment. This is because the building surface is mainly composed of strong alkaline materials such as cement and mortar. The calcium hydroxide content in cement is high, and its pH value is between 10.5 and 13, which will affect the chemical composition of real stone paint. Impact may cause problems such as cracking and peeling of the paint.

Alkali-resistant primer contains additives such as polymer fatty amide, which can bond well with cement and mortar. It also increases the resistance of real stone paint to alkaline substances, ensuring the quality and stability of the paint surface. Therefore, it is very necessary to carry out alkali-resistant primer treatment before spraying real stone paint.

3. How to apply alkali-resistant primer?

When applying alkali-resistant primer, you first need to polish the surface of the building to ensure that the surface is clean, smooth, and free of oil, dust and other impurities. Then use a special alkali-resistant primer for priming to ensure even application and consistent thickness. After the primer treatment is completed, it must be fully dried and solidified before spraying real stone paint.

4. Summary

Therefore, it is very necessary to carry out alkali-resistant primer treatment before spraying real stone paint, which can ensure the quality and stability of the paint surface, prevent cracking, peeling and other problems, and extend the service life and beauty of real stone painting.
