True stone paint as a modern exterior wall decoration of the proud son of the sky, increasingly popular in the coating market, but in the process of real stone paint construction, due to the construction team's unscionable, there are technology defects, there will be various types of construction problems, China Paint Onlinesmall editor for your science and technology exterior wall coating engineering knowledge: real stone paint construction problems should be resolved?
the construction of real stone paint engineering knowledge: real stone paint construction problems should be solved?。 1. Yin and Yang corner cracks
true stone paint spraying process, sometimes in yin and yang corner cracks, because yin and yang angle is two sides cross, if sprayed with real stone paint, in the drying process there will be two different directions of the stress at the same time act on yin and yang corner film, easy cracks.
Solution: Find the yin and yang corner of the crack, spray the thin coating again with a spray gun, spray again every half hour until the crack is covered; , take a thin spray multi-layer method, that is, the surface is dry after re-spraying, spray gun distance to be far, the movement speed is fast, and can not vertical yin and yang angle spray, can only take scattering, that is, spraying two sides, so that the edge of the fog into yin and yang corner.
the construction of real stone paint engineering knowledge: real stone paint construction problems should be solved?。 2. Cracks appear in the plane
the main reason may be because of the temperature difference, suddenly cold, resulting in different drying speed of the inner and outer layers, the table dry and form cracks.
solution: switch to a small nozzle gun, thin spray multi-layer, as far as possible to control the drying speed of each layer, spray distance to slightly better.。 3. Cracks appear in the film-forming process
when spraying, the cover is not uniform or too thick, cracks appear after the coating surface is filmed, or even cracks appear after a few weeks, this situation should be specifically analyzed, in addition to the construction of attention to spraying methods, if necessary, should change the formula, re-trial can remedy this problem.
because of the simple construction process and low cost of excellent performance, the market for real stone paint is becoming more and more extensive, manufacturers are increasing, and competition is becoming more and more intense. In the face of difficulties, manufacturers can consider from environmental protection, high elasticity, non-stick dust and other aspects of the development of higher grades, the prospects will be better than the current.
For high-grade real stone paint must have a supporting construction process, although the manufacturer's paint quality is better, but if the construction staff inexperied, low quality, the performance of real stone paint do not understand or understand is not comprehensive enough, will also cause a variety of problems. Therefore, there is a supporting construction process is necessary.
