In the construction of epoxy floor project, primer coat is the most basic step in the construction of epoxy floor. The primer layer is located between the epoxy floor coating and the base surface of the floor, which can enhance the adhesion of the epoxy floor coating to the ground. Then, some people may ask how much is the use of epoxy floor primer appropriate? In fact, the use of epoxy floor primer is affected by a variety of factors.
1. Ground strength
The most important factor affecting the use of epoxy floor primer is the bond strength of the floor construction base, and then affects the overall strength. In the construction of epoxy floor, the strength of concrete floor is generally greater than C25, and the amount of primer used in the better floor is generally 0.05-0.2 kg/m2. If the ground strength is too low, the ground is loose and easy to sand, the amount of primer used in the epoxy floor will be changed according to the actual environment and the situation.
In addition, the quality of epoxy floors is poor if the base strength of floor construction is low, but the epoxy floors are not coated with proper amount of epoxy primer to increase the adhesion strength of the base. If there is a forklift on the floor, the epoxy floor may be collapsed and cracked together with the epoxy floor.
Therefore, in the construction of epoxy floor, we must ensure that the amount of primer coating is moderate. If the overall strength of the ground is too low, epoxy coating can be selected according to the load-bearing and strength requirements, or the ground can be reconstructed conditionally.
2. Ground wear degree
New and old ground, of course, the degree of wear and tear is different, the old ground according to the length of use and the different degree of use of various loads, the degree of damage to the ground is also different, sometimes the ground will appear in a large area of pits and cracks and other issues, so in the construction of epoxy primer must be before the ground repair It is necessary to control cracks and holes and control the surface evenness. In the face of a relatively new ground environment, its ground strength and smoothness is better, the general dosage is controlled in the range of 0.05-0.2 kg/m2; and in the face of the old ground, the floor professional and technical personnel will take into account the actual situation for your floor control materials, considering customers can not consider.
