Don't panic if your waterproof membrane doesn't adhere well; we'll troubleshoot and resolve it step by step. Common problems mainly include bubbles, wrinkles, misalignment, and edge lifting. The treatment methods and material selection are crucial.
Common Problems and Quick Solutions
Small bubbles: Gently smooth them out with a stiff card or scraper.
Slight wrinkles: Soften them with a heat gun and smooth them out.
Matching: Small misalignments can be fine-tuned; large misalignments require re-application.
Edge lifting: Apply with special adhesive or clean and re-application.
Key Construction Techniques
Substrate preparation: Ensure the surface is flat, dry, and dust-free. The "dryness test tape method" can be used: Apply transparent tape; no condensation after 12 hours indicates it's (qualified).
Adhesive selection:
Wet areas in kitchens and bathrooms: Choose an elastic adhesive.
Open balconies: Choose a UV-resistant adhesive.
Low-temperature environments: Choose a special adhesive that remains flexible at low temperatures.
Construction Environment: Avoid high temperature, high humidity, and strong winds.
Preventive Measures
Substrate Preparation: Thoroughly clean, repair cracks, and ensure a smooth surface.
Material Quality: Use qualified waterproof coatings; avoid expired products.
Construction Process: Follow the principle of "thin layers, multiple coats," ensuring each coat is completely dry before applying the next.
