Construction method of floor paint
Floor paint in the middle of the coating construction, and customer requirements of the thickness and the thickness of each coating after drying. When the construction of solvent and water of mortar layer, a coating is not too thick, otherwise it will lead to less volatile solvent and appeared weak phenomenon, not only extended the construction time will lead to the poor quality of the floor. The most commonly used construction method of coating layer and coating mortar is floor paint coating. According to the viscosity of the coating mortar by coating method.
Customers need more than 3mm thickness, usually using solvent-free coating mortar, using pressure sand process, and then use a trowel troweling, this process can reach 3-5mm and avoid the repeated smear.

If the surface is smooth and floor paint without resistance, not construction mortar layer, and construction putty leveling base, so the cost will be more economical, but life will be slightly shorter than the coating system construction mortar layer.
Requirements of mortar layer floor paint is needed: do not have adverse effects on the surface and bottom primer, such as biting and erosion, and can not penetrate the surface coating containing defects caused by components; in the coating with the coating should be used and the primer and topcoat, with good adhesion, durability should be adapt to and finish. The bottom layer, the middle layer and the surface layer are also required to have air permeability when the coating is required to release the water vapor pressure.
