The final decorative effect of real stone paint is a direct embodiment of quality, in the common problems of the wall, consumers first think of the quality of the exterior wall real stone paint paint is unqualified, but in fact, the vast majority of exterior wall real stone paint peeling, cracking, alkali and other problems are caused by irregular construction. Xiaobian takes you to understand the common problems and treatment methods of real stone paint construction!

Common problem causes & treatment methods

1. Peel and peel

Causes: mainly the use of inferior putty, putty maintenance time is too small and hardness is insufficient, the surface treatment is not clean, the substrate humidity is too large, etc.;

Recommended treatment method: carry out shoveling treatment, and maintain the wall to meet the coating requirements and re-apply.

2. Color aberration

Causes: large color difference between different batches, too long interval between paint applications, etc.;

Recommended treatment method: try to use the same batch of materials for the same wall to shorten the construction interval.

3. Sagging

Causes: Factors such as too thick spraying, too small construction distance, and excessive discharge amount;

Recommended handling:

A. Before each spraying, the spray test should be sprayed on the test plate in advance, adjusted according to the spraying state, and then carry out large-area construction after confirming that there is no abnormality in the color and spraying effect;

B. Before spraying, it is recommended to debug the relevant equipment (air pressure, oil output, etc.) before spraying a large area.

4. Cracking

Causes: too thick spraying, low temperature during spraying or too fast surface drying, etc.;

Recommended treatment: Shovel the severe cracking and then re-spray the application.

5. Anti-alkali

Causes: excessive moisture content of the wall, high alkalinity, project engineering rush, etc.;

Recommended treatment method: carry out shoveling treatment, and maintain the wall to meet the coating requirements and re-apply.

Warm reminder:

There are many kinds of problems that may occur after the construction of real stone paint, and the wall problem is not only the quality of the house itself, but also the problem caused by irregular construction, and the problem of paint has been decided at the beginning of the user's intention to buy. Therefore, when engineering users select paints, they should pay more attention to supervising and assessing the wall construction process, and grasp both "materials" and "work", and both hands should be hard, so as to solve or even avoid various problems such as cracking of real stone paint in advance.
