¡¾Poor Waterproofing Wastes Expensive Materials! 5 Essential Steps for Professional Waterproofing¡¿ As the saying goes, "30% materials, 70% execution." For waterproofing that lasts for decades, the foundational work can never be rushed! A truly professional waterproofing project requires strict execution of these standard steps before and after applying the waterproof membrane: High-Pressure Surface Cleaning Use a high-pressure water jet to thoroughly wash the floor and wall corners, completely removing surface dust, moss, old paint chips, and loose particles to ensure maximum adhesion for the waterproof coating. Meticulous Crack Repair Route out and fill any cracks, honeycombing, or pits in the substrate using high-strength repair mortar or sealant, eliminating potential leak points. Critical Joint Reinforcement (Internal/External Corners & Pipe Penetrations) Wall-to-floor junctions (corners), drainage outlets, and pipe bases are high-risk leakage zones. They must be smoothed into fillet corners (R-corners) and reinforced with non-woven fabric or fiberglass mesh. Primer / Interface Agent Application Once the surface is dry, apply a specialized waterproof primer or interface agent evenly to seal micro-pores, consolidate the substrate, and significantly enhance coating adhesion. Multi-Layer Cross Coating & Water Ponding Test Apply the waterproof membrane in multiple thin, cross-directional coats (ensuring no missed spots or pinholes). After completion, conduct a 2448 hour ponding test to verify zero leakage before handover. Quality is in the Details Choose Expertise for Peace of Mind!
