Tools and Materials Preparation: Before construction, prepare the waterproof backing board, cutting tools (such as an electric cutter or utility knife), measuring tools (measuring tape, level, etc.), adhesive or glue, fasteners (such as screws, expansion bolts, etc.), and protective equipment (gloves, masks, etc.). Ensure that all tools and materials used are of reliable quality to meet construction requirements.
Substrate Preparation: The preparation of the substrate directly affects the construction effect of the waterproof backing board. First, thoroughly clean the substrate surface to remove dust, oil, debris, and other substances that may affect the adhesion. Then, check the substrate for cracks, unevenness, or other problems. If necessary, repair and level it using materials such as cement mortar. Ensure the substrate surface is flat, firm, and dry to provide a good foundation for the installation of the backing board.
