Problems solved by technology

[0004] (1) The fine powder in the middle coating is unevenly dispersed, resulting in poor uniformity of the middle coating;
[0005] (2) The fluidity of the middle coating is unreasonable, and the coating performance is poor, which affects the visual effect of the epoxy floor;
[0006] (3) The construction process is relatively rough, prone to defects such as bubbles, depressions, and poor gloss;
[0007] (4) The compressive strength of epoxy floor is low, which affects the service life

Abstract

The invention discloses a terrace construction technique. The technique comprises base surface processing, mending, scrapping base coat, scrapping floating coat slurry, and scrapping putty layer and finish. The invention further discloses ingredients of epoxy putty and the floating coat slurry. According to the technique, the floating coat slurry has the advantages of good uniformity, high pressure resisting strength after being cured, better visual effect and long service life.

Description

technical field [0001] The invention relates to the technical field of epoxy floors, in particular to a floor construction process. Background technique [0002] Epoxy floor is a high-strength, wear-resistant, and beautiful floor. It has the advantages of seamless, solid texture, good chemical resistance, anti-corrosion, dust-proof, convenient maintenance, and low maintenance costs. Add anti-static, conductive, anti-skid and other characteristics, widely used in workshops, warehouses, shopping malls, parking lots and other places. During the construction of epoxy floor paint, the primer layer, middle coat and surface layer are indispensable. The primer layer closes the gaps in the concrete, preventing underground water vapor, air, and corrosive substances from floating up and causing damage to the epoxy floor. Fine powder such as quartz sand is usually added to the middle coating to improve the wear resistance and thickness of the epoxy floor. The topcoat layer directly f...
