Before application, the substrate must be firm, clean, free of dust, oil, sand, and standing water. Any cracks or defects should be repaired first, and corners should be rounded. The ambient temperature should be above 5℃. Application is strictly prohibited when the surface is frozen, frosty, snowing, or when the temperature is expected to drop below 5℃ within 48 hours.
Before application, thoroughly stir the coating in the container to prevent sedimentation. Apply with a brush or scraper. For flat surfaces, apply one coat at a time. For vertical surfaces, to prevent dripping, apply a thin layer first, allowing it to dry slightly before applying the next coat to the desired thickness. If multiple coats are required, wait until each coat is completely dry (24 hours) before applying the next. Applying a layer of waterproof sealant directly to concrete surfaces (2-3mm thick) provides both waterproofing and adhesion. It reaches usable strength after 7 days. This material can also be used for sealing and caulking, exhibiting good adhesion to concrete, plasterboard, tiles, bricks, marble, wood, and other building materials, making it suitable for sealing, caulking, and waterproofing these materials. When used for waterproofing bathrooms and toilets, apply 1-2 layers of waterproof sealant (2-3mm thick) directly to the concrete surface. Waterproofing will be achieved after 7 days or more of complete drying. This material can also be used in conjunction with polymer cementitious adhesive for roof waterproofing.
Do not expose to rain or water immersion within 24 hours of application. After complete curing, a protective layer such as cement mortar can be applied, or it can be left exposed. Avoid prolonged direct contact with skin. If splashed into eyes, seek medical attention immediately. Protect from fire, sunlight, and rain during storage and transportation.
