Why should the base surface be treated before the epoxy floor paint construction? The main reason is that in order to make the final appearance of floor paint product quality and use effect better, the service life is longer. Maybe everyone is not very familiar with the quality of epoxy floor paint. In addition to the impact of raw materials, it also needs the experience of the construction master to control. The degree of base treatment, the proportion of materials used, the uniformity of coating, construction temperature and other factors will have an impact. According to the epoxy flooring manufacturer, no matter what kind of flooring, there are certain requirements for the base treatment before the construction of epoxy flooring paint. Let's take a look at the following: 1. 基层表面的PH测定必须小于8，要保持一定的碱度，符合地坪漆涂料要求；
1. The determination of PH on the surface of base must be less than 8. It should keep a certain basicity and meet the requirements of floor paint.
2. Surface must be firm and smooth, powder, crisp, bulging, peeling and so on must be paid attention to, and not too smooth, so as to affect bonding, relatively large defects, honeycombs, cracks, holes, linen surface, plate seams, etc. to be tidied up and smooth;
3. The surface of the base must be cleaned in place, no matter dust, clay, demoulding agent, oil stain, white ash and any other impurities that may affect the adhesion of the floor paint, we should pay attention to them. Otherwise, the floor paint will crack, warp and bulge if the scope of these factors is large, it will need to be renovated and polished and re-constructed.
4. The base must be kept dry. The moisture content of solvent coatings such as epoxy flooring paint is not more than 8%, and that of water-borne epoxy flooring paint is less than 10% during construction.
