What should I do if the real stone paint warps and falls off after a heavy rain?

Real stone paint is an exterior wall paint that can realistically display the texture of granite, and can fully demonstrate the texture effect of natural stone. Generally speaking, real stone paint has weather resistance and water resistance, can adapt to stone materials in various climates, and has a service life of 10-15 years.

However, in practical applications, many real stone paints cannot meet the expected standards. Especially in summer, as the number of rainy days in the north increases, phenomena such as edge warping, whitening, and large peeling off of real stone paint become more prominent. These phenomena are mainly caused by the following factors:

1. Human factors: Insufficient experience, low quality of construction personnel and insufficient grasp of real stone paint construction techniques will have an impact on the overall effect of real stone paint.

2. Quality issues of real stone paint products: Low-grade, poor-quality coatings and fake products will affect the use effect of real stone paint.

3. Construction problems: If the base is not strong, it may cause falling off. This is the most common cause of real stone paint peeling off. Before construction, the surface of the base layer should be leveled and cleaned, and impurities should be removed before construction; the new wall should be hard-done for one month before construction; when renovating an old wall, the base layer should be leveled first.

4. Weather and temperature factors: Construction is definitely not possible in bad weather and low temperatures.

To deal with the peeling of real stone paint, first shovel away the uneven and hollow areas until the shovel can no longer be moved, then remove the floating dust and apply moisture-proof sealing paint. Wait for the primer to dry, then scrape the water-resistant putty to level it, and finally spray real stone paint. If bulging occurs, it is generally related to the base material. This may occur if the quality of the putty powder is too poor or if the putty powder is not handled properly before construction.

In short, there are many details that need to be paid attention to in the construction of real stone paint, especially for large projects, and you cannot make mistakes in small details. It is necessary to avoid unevenness, hollowing, and falling off. If it occurs, it must be rectified in time to ensure the quality of the entire real stone paint project. In addition, we should also carefully select putty with good adhesion and real stone paint products that meet the quality standards, and strengthen the technical training of construction personnel.
