Epoxy floor paint is composed of epoxy resin, curing agent, film-forming substances, pigments and so on. The performance of epoxy floor paint produced by different manufacturers is quite different. Single floor paint coatings often can not meet the requirements of various indicators. It is necessary to use different floor paint coatings with comprehensive performance to form composite floor paint coatings. Through years of construction experience, epoxy floor paint manufacturers have shown that when selecting epoxy floor paint materials, each layer of floor paint must be matched, and when matching, different brands and different types of epoxy floor paint should not be mixed as far as possible. The use of epoxy floor paint follows the principle of "attraction of the same sex and exclusion of the opposite sex".1、同种漆涂料配套相容，不同漆涂料配套时，容易出现一些质量上的弊病;
1. The same kind of epoxy floor paint is compatible. When different epoxy floor paint is compatible, some quality defects are easy to occur.2、不同漆涂料配套使用时，地坪漆涂膜过度交联会导致脆性增大，所以烘干型底漆与烘干型面漆配套;自干型底漆与自干型面漆配套。
2. When different epoxy floor coatings are used together, excessive cross-linking of floor coatings will lead to increased brittleness, so drying primer and drying top coatings should be matched; self-drying primer and self-drying top coatings should be matched.3、漆涂层硬度与强度相一致的涂料，配套性较好。例如，如果下层地坪漆涂膜硬度过软，易产生起皱、脱落，强溶剂面漆对耐溶剂差的底层易产生咬底。
3. The hardness and strength of the epoxy floor paint coatings are consistent, and the compatibility is good. For example, if the hardness of the lower floor paint is too soft, it is easy to wrinkle and fall off, and strong solvent topcoat is prone to bite the bottom of the lower layer with poor solvent resistance.
