Epoxy floor paint is a protective film for the ground. It has high adhesion and load, and has some advantages, such as toughness, wear resistance, smoothness and cleanliness, low cost and easy cleaning. The thickness of epoxy floor paint can vary from 0.5 to 5 mm, which is a very thin layer compared with the cement concrete base 5 to 25 cm, so its compression resistance and smoothness mainly depend on the concrete base. Generally speaking, epoxy floor paint requires that the base surface smoothness should be within 2 mm, measured by a 2 m gauge, and the drop should not exceed 2 mm.
If the ground roughness is not up to standard, please refer to the following solutions:
The drop is less than 5 mm.
1. Grinding. With a grinder, the highest point can be grinded parallel to the lowest point.
2. Scraping sand. Epoxy mortar equal thickness floor is suitable for this method. During the construction of intermediate coating, in the process of sand scraping, floor paint and quartz sand are mixed to fill the base of concrete base to achieve leveling effect.
The drop is more than 5mm
If the difference of the base surface is more than 5 mm, it needs to be leveled by a grinder. On the concrete base surface with the difference of more than 5 mm, the cement mortar layer of 3-5 cm should be rebuilt, and the best leveling can be achieved by re-lighting.
