Hebei Ruide spray quick-setting rubber asphalt waterproof coating construction precautions

The following key points should be observed when applying and using spray-applied quick-setting rubber asphalt waterproofing coating: Before application, ensure the substrate is clean and free of oil, dirt, or debris. While wet surfaces (moisture content ≤ 80%) can be used, there must be no exposed water. The ambient temperature should be maintained between 5°C and 30°C. Application should be prohibited during rainy, snowy weather, or winds exceeding force 5 to prevent adverse effects on film quality. When using two components, mix them strictly according to the mixing ratio and avoid adjusting the ratio at will. Spray application should be performed promptly after mixing to prevent premature curing. Spray equipment should be thoroughly cleaned before and after use to prevent residual paint from clogging pipes and affecting subsequent use. Applicators should wear protective equipment such as goggles and non-slip gloves to avoid direct contact with skin. Any contact should be rinsed immediately with clean water. The construction site should be well ventilated and kept away from open flames and flammable and explosive materials to minimize fire risks. After film formation, the coating should be inspected promptly. Any pinholes or bulges should be repaired immediately. During subsequent work, avoid scratching the coating with sharp objects to ensure effective waterproofing. In addition, unused paint must be stored separately and sealed according to its components in a cool and dry place. Before use, it must be checked whether it is within the shelf life. Expired paint is prohibited from use.
