Sometimes, after the construction of epoxy floor paint, there will be color differences, which affect the aesthetics of the whole floor paint project. So what causes the color differences after the construction of epoxy floor paint? Guanglei floor paint manufacturers believe that there are many reasons for the color differences after the construction of epoxy floor paint. First, there is a large amount of precipitation in the epoxy floor paint material, and the color distribution is not uniform, which leads to the difference of color after construction. 1、颜料分层。用多种颜料配置的复色系的环氧地坪漆，在静止存放一段时间后，容易出现分层，其原因和颜料的颗粒有关，重质的颜料会慢慢下沉，轻质的颜料会慢慢上浮。要恢复标准颜色，环氧地坪漆施工前充分搅拌一下即可。
1. Pigment stratification. Epoxy floor paint with multiple pigments is prone to stratification after a period of static storage. The reason is related to the particle size of the pigments. Heavy pigments will sink slowly and light pigments will float slowly. To restore the standard color, mix the epoxy floor paint thoroughly before construction.
2. Free acid corrosion turns green. If the pigments are of metal type, they are vulnerable to free acid corrosion in varnishes and turn green. Metal pigments need to be separated from varnishes.
3. Metal packaging barrels cause darker colors. If the epoxy floor belongs to the type with high acid value, it can not be packed in metal barrels.
4. The light turns yellow. In the formulation of epoxy floor paint, some pigments have poor heat and light resistance, and turn yellow under sunlight.
5. Colour mixing appeared on the spot. Some formulations of epoxy floor paint include pigments that can react with curing agents and resins. How to mix and match colors on the spot can easily lead to color matching failure.
Secondly, the construction technology problems of floor paint builders lead to different colours after construction.
In the process of construction, the builders did not master the strength well, which resulted in the different thickness of the coatings, resulting in the situation that the thicker coatings had dark color and the thinner coatings had light color. Or the builder does not work continuously in the construction process, breaking materials in the middle; or the use of different batches of topcoat in the construction process, which will lead to differences in color before and after.
