Non Toxic And Odor Safe Polymer Modified Cement Waterproofing Water Based

Js Polymer Cement Waterproof Coating Manufacturer China

Material Advantages

1. Combined rigid‑flexible performance: Polymer emulsion provides flexibility while cement powder offers strength. The coating tolerates minor substrate cracking and deformation.
2. Water‑based & eco‑friendly: Solvent‑free, non‑toxic and odor‑safe for indoor confined‑space construction.
3. Suitable for damp substrate: Can be applied on damp surfaces without standing water, delivers strong adhesion to concrete and cement mortar.
4. Versatile application methods: Two‑component on‑site mixing. Applicable by brush, roller or trowel. Forms seamless film on complex details such as corners and pipe roots.
5. Direct finishing available: Plastering, leveling and tile laying can be performed directly on cured coating without extra primer treatment.
6. Excellent immersion resistance: Suitable for long‑term immersion structures such as water tanks with reliable anti‑seepage performance.
7. Alkali and aging resistance: Resists alkali and water‑immersion aging, ideal for underground and hydraulic structures.
8. Multiple grades for selection: Type I for higher elasticity; Type II & III feature higher strength for residential waterproofing.

Construction Methods

1. Substrate Preparation Make substrate solid and flat. Remove dust, oil and loose particles. Repair holes and cracks in advance. Keep substrate damp without standing water. Thoroughly clean vulnerable details including corners, pipe roots and construction joints.
2. Mixing Add liquid component first, then powder component according to mixing ratio. Electrically stir to get homogeneous lump‑free slurry. Mix on‑demand and use within pot life. Do not dilute expired slurry with extra water.
3. Detail Reinforcement Apply one coat of slurry on leakage‑prone positions such as pipe roots, corners and construction joints. Reinforce with non‑woven fabric if needed. Start large‑area construction after full drying of reinforcement layer.
4. Multi‑coat Application Apply 2‑3 cross‑direction coats by brush, roller or trowel. Each coat must be fully dry and non‑sticky before next application. Apply coats in cross directions. Control total film thickness, avoid missing coating and material accumulation.
5. Curing Construct within 5‑35℃, avoid rainy weather. Carry out natural curing after coating surface dries. Prevent rain wash and mechanical damage. Proceed to next steps after full curing.
6. Finished Product Protection No foot traffic or water immersion during curing. Plastering, tiling or backfilling can only be carried out after complete film formation.
