环氧地坪漆表面暗淡无光的原因：1、因为贪图便宜，选择了环氧地坪漆价格相对较低却质量有问题的材料，导致施工后的环氧地坪达不到预期的效果。2、环氧地坪漆材料使用时没有按照厂家的要求加入了过量的稀释剂，或者选择的稀释剂不配套，沸点低，挥发过快。

The reasons why the surface of epoxy floor paint is dull and dull are as follows: 1. Because of the greed for cheapness, epoxy floor paint has been chosen for materials with relatively low price but poor quality, resulting in the construction of epoxy floor paint can not achieve the desired effect. 2. When using epoxy floor paint materials, excessive diluents were not added according to the requirements of manufacturers, or the selected diluents were not matched, boiling point was low and volatilization was too fast. 3、在上一道涂层未完全干透就进行面漆的施工，导致环氧地坪漆黯淡无光。

3. The application of topcoat before the last coat is completely dried leads to a dull epoxy floor paint.

4、基层地面没有使用环氧地坪研磨机打磨平整，地面粗糙，导致环氧地坪漆施工后也不平整，光线折射导致涂膜表面光泽度不够。

4. The base floor is not polished flat by using floor grinder, and the ground is rough, which results in the unevenness of epoxy floor paint after construction. The light refraction results in the insufficient gloss of the coating surface.

5、环氧地坪漆施工时环境温度过高，过高的温度会导致环氧地坪漆起皱，影响表面的光泽度。

5. When epoxy floor paint is constructed, the ambient temperature is too high. Excessive temperature will cause wrinkling of the floor paint and affect the gloss of the surface.

6、环氧地坪漆施工现场环境湿度过大(相对湿度80%以上)，导致环氧地坪漆漆膜吸收水分后泛白，失去光泽。

6. The environmental humidity of epoxy floor paint construction site is too high (the relative humidity is over 80%), which causes the epoxy floor paint film to become white and lose luster after absorbing water.

避免环氧地坪漆黯淡无光的方法：

Method to avoid dull epoxy floor paint:

1、选择正规地坪漆厂家生产的有质量保证的材料。

1. Choose materials with quality assurance produced by regular floor paint manufacturers.

2、严格按照地坪漆厂家的要求，添加环氧地坪漆配套的稀释剂。

2. In strict accordance with the requirements of flooring paint manufacturers, add diluents for epoxy flooring paint.

3、面漆施工时一定要等待上一涂层完全干透。

3. When topcoat is applied, it must wait for the top coat to be completely dry.

4、环氧地坪漆施工前一定要用地坪研磨机将地面打磨平整，并将油污、杂物等清理干净。

4. Before the construction of epoxy floor paint, it is necessary to use floor grinder to smooth the ground and clean up the oil and sundries.

5、环氧地坪漆最佳施工温度是5-25摄氏度，施工时要避开高温时段;

5. The optimum construction temperature of epoxy floor paint is 5-25 degrees Celsius, and high temperature period should be avoided during construction.

6、环氧地坪漆施工时环境湿度不能高于80%。

6. The ambient humidity should not be higher than 80% during the construction of epoxy floor paint.
