1. Base layer treatment: Clean the surface of the base layer. The base layer can be moist, but there should be no open water. If the base layer is dry, sprinkle water to moisten it.
2. Prepare cement slurry: add water directly to cement (not less than 32.5R grade Portland cement), cement:water = 1:0.3~0.4 (weight ratio, reasonable investigation based on actual situation), stir with an electric mixer 1~2min, mix well and let stand for 5~8min.
3. Membrane pasting: Use a trowel or scraper to evenly apply the mixed cement slurry on the base layer. While applying and scraping, lay the polymer composite self-adhesive waterproofing membrane on top and exhaust the pressure. Reality.
4. Seam pasting: The seams of the roll material are cold self-adhesive. Adjacent short-side joints should be staggered by more than 1m; when constructing long-side joints, tear off the reserved isolation tape on the self-adhesive edge of the joint, and paste directly in line with the pasting mark line; then use special sealing paste to strengthen the sealing head.
