What are the requirements for concrete base surface in epoxy floor construction? 1. The concrete base surface is smooth and compact, and the strength condition is not less than C20; too poor strength will reduce the compressive, impact resistance and durability of epoxy floor coating; 2. The ground evenness is usually within the 2M boundary, and the drop is not more than 2mm; if the drop is large, the ground mortar layer needs to be thickened to reduce the drop; 3. If the ground to be coated is at the bottom. If the groundwater level is high, the concrete bottom should be waterproofed to prevent the evaporation of groundwater from jacking up the epoxy floor coating and causing blistering and crusting.
4. The concrete is thoroughly dried for at least three weeks, and the moisture content is not higher than 6%. In the course of maintenance, it is easy to prevent rain and water accumulation on the ground, otherwise the moisture content of one-sided concrete will exceed the standard.
5. The strength of concrete leveling layer should not be lower than C20 and the thickness of concrete leveling layer should not be less than 30mm on floor, reinforced concrete beams and concrete cast in stages.
6. Shell-proof, concrete layer and mud leveling layer need to be poured together. If the concrete layer is tampered first, the thickness of mud layer is not less than 4cm, and the condition of forklift lane is thicker. No sand, good hardness and no sign of cement powdering are required.
A. High quality cement, and the higher the label, the better.
B. The newly poured cement slurry layer should be fully maintained. The cement base surface is flat, no rough, honeycomb linen surface, cement knot, and the ground flatness is not greater than painting.
7. When repairing damaged concrete, fine stone mixed soil can be adopted. The strength grade should not be less than C20 and the thickness should not be less than 30mm.
8. Fine and flexible parts, such as the periphery of the downspout pipe and the door sill, should be level and the edges and corners should be straight.
