In order to ensure the construction quality of epoxy floor paint, the base should have the following conditions before the construction. 1. After repairing, the unevenness of the base and the dislocation of the joints of the base should be based on the type of epoxy floor paint and the coating thickness and surface decoration. State and so on
Within the allowable range.
2. Surface base should not be attached to dust, grease, rust point, sand paddle, coagulant and seepage.
3. The strength and rigidity of the surface of the ground base should be higher than that of the coating. For example, the surface of the loose base or the aerated concrete base should be pre-painted with solidified cross-linking solvent-based base coating to reinforce the surface of the base.
4. The damage, cracks and separation of the surface of the ground base should be repaired in advance. The screaming, moisture content and roughness of the paddle in the repaired part should be the same as those in the other parts. If they are not the same, the sealing material should be coated.
5. The moisture content of the ground base should be within the permitted scope according to the type of floor paint.
6, the pH value of the base should be within the permitted scope according to the type of epoxy floor paint coating.
7, metal parts, screws and nails installed on the ground base should be disposed.
