Flexible Rigid Composite Polymer Modified Cement Waterproofing TypeⅠ No Crack At -10℃

Flexible Rigid Composite Js Waterproof Coating

Substrate Preparation

The substrate shall be sound, flat and clean. Remove laitance, dust, oil stains and loose layers. Repair holes and cracks in advance. Fully wet the substrate before construction, keep it damp without standing water. Clean and polish vulnerable details such as corners, pipe penetrations and construction joints.

Two‑component Mixing

Follow the mixing ratio strictly. Add liquid component first, then powder component. Electrically stir for 2‑3 minutes until smooth lump‑free slurry is obtained. Mix on‑demand and use within pot life. Do not re‑mix expired slurry by adding extra water.

Detail Reinforcement

Apply a thin coat of JS slurry on leakage‑prone areas such as pipe roots, wall‑penetrating pipes, corners, construction joints and post‑pouring belts. Lay non‑woven or glass‑fiber fabric for positions with large deformation. Proceed to large‑area construction after reinforcement layer is fully dried.

Multi‑coat Large‑area Application

Apply 2‑3 cross‑direction coats by brush, roller or trowel. Apply next coat only when previous coat is dry and non‑sticky. Apply successive coats in perpendicular directions. Strictly control total film thickness, ensure uniform coating without missing or accumulation.

Curing & Curing Period

Suitable construction temperature: 5‑35℃. Stop construction in rainy, snowy and windy conditions. Conduct natural curing after surface drying. Prevent rain wash and direct strong sunlight. Keep good ventilation for full cross‑linking and curing.

Finished‑product Protection & Subsequent Work

Avoid foot traffic, impact and water immersion during curing period. After the coating achieves full performance, plastering, mortar leveling, tile laying and backfilling can be carried out directly without extra interface treatment.
