As we all know, in order to make a high quality floor, in addition to the quality factors of floor paint coating will directly affect the overall quality and service life of the floor, what other factors will affect the quality of the floor project? The situation of the base and construction environment should also be taken seriously by everyone, the specific situation please see the following analysis:
1. substrate surface smoothness
Substrate surface smoothness refers to the degree of surface concavo convex. We usually use 2m's ruler to measure the spacing of the gaps, and below 3mm is a good flatness.
2. base surface strength
Base strength is a decisive factor affecting the epoxy floor project, because if the base is damaged by force, it will cause damage to the entire floor. Or if the base strength is not enough, the floor coating and the substrate will be pulled apart, so we require the base strength to be greater than 25 MPa.
3. base level drying degree
Film bubbling and delamination are due to the moisture content in the concrete and mortar ground, which will greatly reduce the bond strength between the base and the coating, so to maintain the dryness of the base. In the epoxy floor engineering, it is generally required that the moisture content of the base is less than 6%, and the drying time of the base is more than 28 days.
4. environmental conditions
Before carrying out the epoxy floor project, we should pay attention to investigating the construction environment besides the base surface treatment.
