Floor water paint What method is used to deal with ground moisture during epoxy floor construction?

Floor is the ground floor room and soil layer contact part, it withstands the load of the ground floor room, requires a certain strength and stiffness, and has moisture,waterproof, warm, wear-resistant performance. There is a close relationship between the formation and the outdoor site of the building, and the relationship between the floor and the platform, the steps and the edge of the building should be handled well, so that the handover between the building and the site is clear and harmonious as a whole.
how to deal with the wetness of the construction ground of the epoxy floor? As we all know, epoxy floor paint construction substation concrete moisture content should not be higher than 8%, too high water content will seriously affect the construction quality of epoxy flooring, will make the floor of the poor film adhesion, surface foam, de-layering and other undesirable phenomena
Nation

There are several main reasons for the return tide
First, late spring and early summer, the temperature rises, spring rain, air humidity, resulting in indoor air saturation, and second, the ground temperature rises slowly, has not been raised in a short period of time. Surface condensation is produced when moist, saturated air flows over low-temperature ground. This phenomenon is commonly known as the return tide. Soil layer, when the soil quality should be shallow burial, on the other verse, the foundation burial depth should be increased.
(2) water table. The foundation is best placed above the water table.
(3) freeze depth. The foundation depth should be greater than the frozen depth of the soil layer in winter.
flooring custom to everyone to talk about several ways to deal with epoxy floor construction ground moisture.
to do waterproof layer
for the high water content, and water content has a rising trend of concrete substation, need to do a professional waterproof layer, to prevent late water seepage caused by the failure of the floor.
to maintain the ventilation of the construction site
the construction site to maintain a state of ventilation, the circulation of air can speed up the evaporation of water in the concrete substation, is conducive to improving the adhesion of epoxy floor paint and substation.
heating
the temperature of the concrete substation can speed up the evaporation of water. Guangzhou Litek recommends the use of air heating or radiation heating, not fire source heating, because fire source heating will increase the air fog point temperature, so that water vapor condensation in concrete.
permeable system
permeable system has a very high water penetration rate, to ensure that the base surface water vapor escapes through the coating, to avoid the coating foaming off, suitable for the substation can not be installed waterproof layer.
Epoxy flooring is suitable for some places with higher requirements for sanitary conditions such as hospital floor, food factory workshop floor, pharmaceutical factory workshop floor, experimental floor, machine room floor, etc. , and requires anti-stamping corrosion-resistant ground such as underground parking lot, factory garage (forklift) and so on.
