Layering and peeling of epoxy floor paint coating occur in the use process. 2. The wear of the epoxy floor paint in the driving passage is more serious than that in the parking space, especially at the entrance, exit and corner. 3.

Cause analysis of problems in the use of epoxy floor paint in underground parking lot:
1. The reason why epoxy floor paint has been widely used in indoor concrete floor is that epoxy floor paint has a very good adhesion to concrete floor. Under normal circumstances, the occurrence rate of delamination and spalling between epoxy floor paint and concrete floor is basically zero. At present, there are two main reasons why epoxy floor coatings are delaminated and exfoliated in a large area in the course of use.
A. The construction of the original concrete floor is not up to the standard, and the phenomenon of sand and silting is serious.
B. Before the construction of epoxy floor paint, no water content index of concrete ground was detected, and no waterproof layer was made on the ground of underground parking lot.2、行车通道由于车辆长期频繁碾压，导致环氧地坪漆磨损过快，因此建议地下停车场行车通道做环氧砂浆地坪。
2. Because of the frequent rolling of vehicles for a long time, the wear of epoxy floor paint is too fast. Therefore, it is suggested that the underground parking passage be made of epoxy mortar floor.3、地下停车场由于车辆的进出，经常会带入一些砂子、石子等硬物，非常容易划伤地面，这就需要做好地下停车场环氧地坪漆的养护工作，专业的养护能有效延长地下停车场环氧地坪漆的使用寿命。
3. Underground parking lots often bring in some hard objects such as sand and stone due to the entry and exit of vehicles. It is very easy to scratch the ground.
