When purchasing wholesale really stone paint will see five really stone paint quality detection

How really stone paint through inspection, often occurs in the analysis of external coating of problem such as craze, white is the most obvious.

The following five test requirements of the customer when buying and wholesale really stone paint should pay attention to. Really stone paint construction at the grass-roots level five testing requirements: one, the strength of the grass-roots strength and the type and quality has a lot to do at the local level. In general, the strength of the concrete base is highest, followed by mortar and gypsum board. At the grass-roots level low intensity will affect the coating adhesion. Qualified at the grass-roots level shall not have powder, sand, empty drum, layered, cracking and spalling. Second, the non-uniformity of roughness at the grass-roots level will affect the final adornment effect really stone paint. Roughness check mainly includes four projects: smooth surface, vertical Angle, vertical elevation and square Angle of Yin and Yang, Yin and Yang.
