The construction of epoxy floor paint requires that the strength of concrete cement ground should be above C20. Otherwise, it can not be constructed. There will be some problems such as poor adhesion between epoxy floor coating and base, crushing and cracking of floor. But in the actual construction process, not all the concrete cement ground strength will meet the standard. How to solve the problem of insufficient ground strength in floor paint construction? Usually, there are three reasons for low ground strength in floor paint construction. 1、浇注地坪漆基面的水泥标号过低。
1. The cement label of the base surface of the casting floor paint is too low.
2. The proportion of cement mortar is unreasonable and the amount of cement added is too small.
3. The maintenance work during the ground maintenance period is not in place.
Solutions to low strength of floor paint construction base surface:
If the strength gap between the construction base and the required strength is too large and the surface of the floor is loose, milling treatment should be carried out to remove the substandard concrete, and then re-pouring the concrete with sufficient strength.
If the strength of the base surface of the floor paint is not far from the required strength, it can be strengthened by increasing the amount of epoxy primer. Read "Operating Procedure of Epoxy Floor Paint".
The most important factor affecting the use of epoxy floor paint primer is the strength of the construction base of the floor paint. The construction of epoxy floor paint generally requires that the strength of concrete ground is greater than C20. If the ground strength is too low, the ground is loose and easy to sand, the use of epoxy floor primer will be greatly increased. The lower the ground strength, the greater the amount of primer used.
If the strength of the construction base is low, but not enough epoxy floor primer is applied to increase the strength of the epoxy floor, the quality of the epoxy floor is poor. If there are forklifts and other heavy objects on the floor, the epoxy floor may be collapsed and fractured together with the epoxy floor base. Therefore, in the construction of epoxy flooring, we must ensure that the amount of primer coating is sufficient. Specifically, we can refer to the "factors affecting the amount of epoxy flooring primer and construction considerations".
