Take measures to prevent blisters:
1. Make a waterproof layer on the grass-roots level to prevent water vapor from seeping through to control the moisture content in the base layer or the waterproof layer within 8%, and the compressive strength of the base layer or the waterproof layer is greater than 20 MPa, and perform epoxy construction.
2. To improve the adhesion of the epoxy layer and the base layer or the waterproof layer, to overcome the expansion force at the initial blisters to avoid blisters.
3. In the epoxy layer construction, the primer layer should be made of good quality materials. First, allow a part of the epoxy to penetrate into the base layer or the waterproof layer to form an integral whole. Second, it is to improve the adhesive force, and to leave less after curing. Residual substances or chemical gases.
4. Avoid sun exposure after epoxy construction and reduce the change in the temperature difference between the epoxy layer surface and the inside.
5. The construction on the base or waterproof layer must be cleaned. There is no gap between the epoxy layer and the base layer or waterproof after construction.
In short, the waterproof material must be selected, with the following points: 1) impermeability and gas impermeability; 2) pressure resistance, strength greater than 20MPa; 3) excellent adhesion to the ground; 4) easy with epoxy resin Bonding forms a whole. The waterproof layer shall not be used for 3 days after the completion of construction to protect the finished product.
Five Steps to Solve the Problem of Foaming on Epoxy Floor Construction
1. To solve the epoxy layer from blisters, but also mainly to solve the epoxy floor construction in the "three fears" (1) afraid of water; (2) afraid of the sun; (3) afraid of dust.
