For the rainy and humid South, waterproof layer is essential, which is related to the overall quality of the project
.
Waterproof layer has a very important influence on the service life of epoxy floor, especially the epoxy floor system of basement and first floor
.
If the waterproof layer is not well done, the later stage of the floor is prone to bubble, delamination and other phenomena
.
Before the construction of waterproof layer, it is necessary to deal with the base surface to ensure that the moisture content is below 4%
.
If the ground is too wet, you can use the method of blast or sunlight to speed up the drying of the ground
.
Generally, the drying time of base course is more than 28 days
.
After the base surface is treated, the construction of waterproof layer can be started
.
The construction of waterproof layer generally has two situations: the first is to lay fine sand; the second is to lay plastic film, which should be carried out after the ground is backfilled
.
First, a layer of fine sand should be laid on the surface of the backfill, followed by asphalt felt and plastic film, both of which should be opaque
.
Finally, the concrete layer is poured
.
At least 10cm overlapped waterproof coating is required at the lap joint of two plastic films
.
The waterproof coating is a kind of viscous liquid brushed on the building surface
.
The liquid will form a layer of film through the volatilization of solvent or water, or the chemical reaction of two components
.
This film insulates the surface of the building from water, thus playing the role of waterproof and sealing
.

.
First, a layer of waterproof coating is applied on the cement floor of epoxy floor paint construction to form a waterproof isolation layer
.

.
Then the cement mortar protective layer is laid
.
The construction of epoxy floor paint is carried out on the protective layer of cement mortar
.
In order to get a high quality epoxy floor, the construction of waterproof layer is an essential process
.
If you wait until there is a problem to realize the importance of waterproof layer, it is really only regret
