Epoxy floor paint requires a very high water content on the base floor, which can not be higher than 8% in general. Therefore, before the construction of epoxy floor paint, it is necessary to know whether the ground has been waterproof, especially in the lower water level areas such as underground parking lot and basement. For the construction base without waterproof layer, it is necessary to lay waterproof layer before construction to ensure the construction quality of floor paint project. Waterproof layer plays a very important role in the construction of epoxy floor paint. Its quality directly affects the anti-moisture performance of the ground and the service life of the epoxy floor paint. Seriously, it will also cause the defects of moisture regain, foaming and peeling off of the epoxy floor paint.
Construction method of waterproofing layer on base surface of floor paint construction:
Before the construction of waterproof layer, the base surface should be treated well to ensure that its moisture content is less than 5%. If the ground is too wet, it can be dried by a high-power fan or irradiated by a solar lamp on the base. Generally, the drying time of the base requires more than 28 days.
1. Laying fine sand and film
Laying plastic film on the ground after backfilling. First, a layer of fine sand is laid on the surface of backfill soil, then impermeable felt and plastic film are laid, and finally concrete layer is poured. It should be noted that the overlap of the two plastic films should be at least 10CM. Otherwise, groundwater can easily penetrate through the gap between the two plastic films into the construction base of the floor paint between the surface and the epoxy floor paint coating, which will cause foaming or even falling off of the epoxy floor coating.
2. Coating Waterproof Coatings
The construction method of waterproof coating is to first coat a layer of waterproof coating on the cement floor to form a waterproof isolation layer, then to construct a layer of cement mortar protective layer, and finally to construct a floor paint on the cement mortar protective layer.
防水涂料是指涂刷在建筑物表面上，经溶剂或水分的挥发或两种组分的化学反应形成一层薄膜，使建筑物表面与水隔绝，从而起到防水、密封的作用的粘稠液体。 塑料薄膜和防水涂料都能有效防止地下水渗透， 防止环氧地坪漆涂膜起泡脱落， 保证环氧地坪工程质量。
Waterproof coating refers to the viscous liquid which is painted on the surface of buildings and formed by volatilization of solvent or water or chemical reaction of two components, so as to isolate the surface of buildings from water, thus playing the role of waterproof and sealing. Plastic film and waterproof coating can effectively prevent groundwater penetration, prevent foaming and falling off of epoxy floor paint film, and ensure the quality of epoxy floor engineering.
