According to the construction experience of Guanglei Epoxy Floor Paint Factory, the following ground problems may occur during the construction of epoxy floor paint. The epoxy floor paint manufacturer suggests the following solutions: 1. Treatment schemes for concrete surface with cracks, peeling, flax, sand or oil contamination, such as slight cracks in a small area of foundation ground (without affecting epoxy). During floor construction, the problem ground is treated, and the cracks are filled with epoxy coating.
If the surface is desquamated, linen surface and sand-lifting parts are cleaned, the surface of the ground is strengthened by using glazed epoxy sealed primer material to enhance the adhesion of the foundation ground, and epoxy mortar material is used to repair the desquamation and cracks in order to ensure the levelness of the whole ground. Our unit will charge the cost of reinforcing material according to the use of the base reinforcement material.
Special concrete ground treatment二、基面含水率在6%以上时施工处理方案：
2. When the water content of the base surface is above 6%, the construction treatment scheme shall be as follows:
Generally, epoxy floor paint requires no more than 4% moisture content of the base surface. If the moisture content of the concrete base surface is high and wet, mud leveling layer can be chosen to solve the problem of high moisture content and humidity of the base surface; (Cost added)
When the moisture content is not very high, it can be treated as a moisture-proof layer or waterproof primer as a sealing material to do a good job of drying the concrete foundation ground.
If there is no moistureproof layer and waterproof layer when laying concrete foundation layer, we can use moistureproof paint construction, waterproof paint bottom sealing, in view of the rising water content of the ground, indicating the trend of groundwater upstream seepage, we need to do a thorough waterproof bottom sealing.
During the construction of epoxy floor, when the concrete foundation is wet and the water content is high, we must solve the problem of high water content according to the above methods before laying epoxy floor paint. Otherwise, the phenomenon of moisture regain, water rising and delamination will occur. (Moisture-proof layer shall be added according to the specific conditions of the site)
Construction site of epoxy floor paint三、空气中湿度在85%以上时施工处理方案：
3. Construction treatment scheme when air humidity is above 85%:
According to our unit's experience in epoxy floor construction, when the humidity exceeds 85%, Guanglei floor paint manufacturer recommends the use of waterborne polyurethane floor construction.
