When it comes to the construction of epoxy floor paint, many people know, and according to the performance of the floor, epoxy floor paint can be divided into ordinary epoxy floor, mortar epoxy floor, self-leveling epoxy floor, anti-static epoxy floor and anti-corrosion epoxy floor. But in the construction of epoxy floor paint, what are the key points? The following epoxy floor manufacturers help you sum up the relevant knowledge. 一、新浇筑的混凝土地面：混凝土主要是由水泥、砂、石、灰泥等组成，吸水率大、碱性强、干燥慢。新浇注混凝土的表面泛碱物和吸水率是影响涂装质量的关键，所以，在涂装前要干燥相当长的时间，除非特别减水，否则一般要求干燥28D以上，基面含水率要小于6%。表面泛碱物要彻底清除，必要时做中和处理。混凝土强度要求达到C25以上。地面平整度用2m靠尺检查，间隙不得大于3mm。
First, the newly poured concrete ground: concrete is mainly composed of cement, sand, stone, mortar and so on. It has high water absorption, strong alkalinity and slow drying. The surface pan-alkali and water absorption of newly poured concrete are the key factors affecting the quality of coating. Therefore, it is necessary to dry for quite a long time before coating. Unless water is reduced, it is generally required to dry more than 28D and the moisture content of the base surface is less than 6%. Surface pan-alkali should be thoroughly removed and neutralized when necessary. The strength requirement of concrete is above C25. The ground roughness shall be checked by 2m ruler, and the clearance shall not be greater than 3mm.
2. Old Ground: Old Ground that has been used should be repaired. If there are wax layer, oil pollution, chemical corrosive medium and old coating, the corresponding treatment should be taken.
3. Main points of floor paint: The self-leveling performance mentioned in floor paint mainly refers to topcoat, primer and mid-coat are the same as other types of floor paint. Self-leveling surface paint is the key to determine the appearance and use effect of epoxy self-leveling floor. The construction of epoxy self-flowing surface paint mainly takes the form of batch scraping with a trowel. The self-flowing surface paint is gently driven by the toothed side of the trowel to produce a little power, and then the self-flowing surface paint is leveled by itself. In construction, temperature, construction method and construction technique directly affect the effect of epoxy self-leveling floor.
