In the application process of manual asparagus polyurea, some users have encountered many problems, and recently some users have told us that after the manual asparagus polyurea coating is dry, how can cracks occur? When such a problem arises, it is necessary to get rid of the old asparagus polyurea coating and re-engineering construction, for the situation of cracks after the construction of the manual asparagus polyurea project, Kedi environmental protection asparagus polyurea to us to interpret the root cause of the cracking after the construction of the manual asparagus polyurea project.
The construction of manual polyurea engineering must follow the principle of "thin brush many times", and the single coating is too thick, which is easy to cause the surface of the polyurea coating to dry and solidify quickly, and the inside to dry and solidify slowly, and the polyurea of asparagus cracks due to the inconsistency of the dry solid solid.
Therefore, in the process of engineering construction, the coating of polyurea coating should not be too thick, and must be applied thinly. Once the surface is dry, brush it a second time until you reach the desired wall thickness standard.
In the construction process of the manual asparagus polyurea project, it must be strictly required to operate in accordance with the standards of construction technology, and there can be no luck or sloppiness.
For example, in today's winter polyurea industry, a sentence is three points of materials, seven points of engineering construction, no matter how good the material, the construction of the project is not standardized, and it is easy to cause problems. Therefore, for Tiandong polyurea, we must standardize the construction of the project to avoid greater losses caused by rework in the later stage, and also cause unnecessary trouble to us!
