During the construction of real stone paint, various problems may occur due to the unprofessionalism of the construction team. In order to ensure the quality of the real stone paint construction, this article will address the common problems and their solutions in detail.
1. Cracks in the corners of yin and Yang
In the spraying process, the corner of yin and Yang is the intersection of two surfaces, which is easy to produce cracks. This is due to the drying process, the two different directions of tension acting on the yin and yang corners of the coating film, resulting in the formation of cracks.
Solution:
When cracks are found at the yin and yang corners, use a real stone paint spray gun to apply a thin overspray, and repeat the spraying every half hour until the cracks are completely covered. When spraying new yin and yang corners, should take a thin spray multi-layer method, that is, the surface is dry and then re-sprayed, spraying gun distance should be far away, the movement speed should be fast, and can not be vertical yin and yang corners of the spray, can only take the scattering method, so that the edge of the mist flower swept into the yin and yang corners.
2. plane cracks
Plane cracks are usually due to drastic weather changes, resulting in different drying speeds between the inner and outer layers, the surface layer is dry and the inner layer is not dry, thus forming cracks.
Solution:
Change to use a small nozzle of the real stone paint spray gun, thin multi-layer spraying, try to control the drying speed of each layer, spraying distance slightly farther appropriate to ensure uniform drying.
3. Cracks in the process of film formation
When spraying real stone paint, if the coverage is not uniform or too thick, the real stone coating is easy to crack after the film formation, sometimes even after a few weeks.
Solution:
This situation needs to be analyzed specifically. In addition to paying attention to the spraying method, the formula should be changed and the composition of the real stone paint should be readjusted if necessary. For high-grade real stone paint, it is necessary to use matching construction technology, even if the quality of the paint is very good, if the construction personnel are inexperienced, unskilled, and do not understand the performance of the real stone paint or do not understand it comprehensively, the same will be a variety of problems. Therefore, it is very important to strictly comply with the matching construction process.
Summarize
In the process of real stone paint construction, the mastery of craftsmanship is crucial. Through the above solutions, the common cracking problems in the construction of real stone paint can be effectively dealt with to ensure the construction quality and effect. At the same time, the construction personnel should constantly improve the technical level, familiarize with the performance of the real stone paint and the correct construction process, in order to reduce the problems that may occur in the construction process.
