Shanghai EVH Industrial Co., Limited specializes in manufacturing and exporting all kinds of waterproof membrane and coating.
Installing a self-adhesive bituminous membrane requires proper preparation and careful application to ensure effective waterproofing. Here’s a step-by-step guide:
Self-adhesive bituminous membrane
Utility knife
Measuring tape
Roller or hand press
Primer (if required)
Brush or roller for primer application
Prepare the Surface
Ensure the surface is clean, dry, and free of dust, grease, or loose particles.
Fill any cracks or holes with an appropriate filler and let it cure.
Apply Primer (if required)
Some surfaces may need a primer to enhance adhesion. Apply it evenly with a brush or roller and let it dry completely.
Measure and Cut the Membrane
Measure the area to be covered and cut the membrane to size, leaving extra for overlaps (usually 2–4 inches).
Position the Membrane
Lay the membrane on the surface to align it correctly before peeling off the backing. Adjust as necessary.
Peel and Stick
Peel off a portion of the protective backing from one end.
Gradually stick the membrane to the surface, peeling the backing as you go.
Press and Smooth
Use a roller or hand press to firmly adhere the membrane, ensuring there are no air bubbles or wrinkles.
Seal Overlaps
Overlap adjacent sheets according to the manufacturer’s recommendations, usually 2–4 inches. Press firmly to ensure a watertight seal.
Inspect the Installation
Check for bubbles, loose edges, or misalignments and fix them promptly.
Finish the Edges (Optional)
Apply additional sealant or adhesive to exposed edges if specified by the manufacturer.
