Material selection of moisture-proof epoxy floor paint is very important. The ground of epoxy floor paint garage is widely used in daily life. Because the ground of epoxy floor paint garage is generally built in basement, when the ground of epoxy floor paint garage is constructed, if the cleaning, wetting and drying degree of the base is not handled properly, the moisture in the foundation will pass through the concrete of floor paint. The infiltration of capillary holes makes the surface of garage floor more and more wet, which is the phenomenon of moisture return of underground garage floor. 严重的时候，会损害整个地面，造成无法修补。随着气温变化的时候，空气中的湿度也会有所变化，而当金刚砂地坪车库地坪地下室温度较低的时候，很容易在环境改变的情况下发生返潮的现象，不过，当环境返回到自然状态的时候，这种现象就会消除。
In serious cases, it will damage the whole ground and make it impossible to repair. As the temperature changes, the humidity in the air will also change, and when the temperature of the garage floor basement is low, it is easy to return to the tide when the environment changes. However, when the environment returns to the natural state, this phenomenon will be eliminated.
So material selection is a very important link, especially when the quality of curing agent floor paint concrete is poor, the compactness of the garage floor is poor, and there will be many capillary holes in the concrete, so that the phenomenon of moisture return on the ground is more likely to occur, so we should pay great attention to material selection during construction.
If the floor is damaged, it will not only be easy to ash, sand and other issues, but also affect its protection of the ground. So once the dust enters the machinery, it will cause mechanical damage, so it is necessary to renovate the old floor in the later stage. If there are holes in the ground, epoxy floor paint manufacturers recommend using a grinder to grind, remove the holes in the ground, and then use mortar or cement to treat the holes.
If there is oil pollution on the ground, it should be cleaned up before construction. In the process of renovation, the first thing to do for the old floor is to use professional epoxy grinding equipment and remove it completely, and then according to different types of epoxy floor construction. Poor material and construction quality often lead to ground cracks. If cracks are found, a cutting machine can be used to cut the cracks into V-shaped grooves and then pour epoxy mortar into them to make them flat.
