Product Overview

SBS modified bitumen waterproof membrane is a classic high-performance torch-on waterproof roll. Modified with SBS elastomer, it features outstanding low-temperature flexibility, tensile strength and anti-aging performance. It adopts hot melt torch application, forms a tight seamless waterproof layer after construction, suitable for all kinds of building waterproof projects.

1. Lay the roll from low position to high position, align and straighten each roll, then roll it back.
2. Heat and bake the membrane surface evenly while rolling forward, then paste and seal the edge.
3. Finish the whole roll paving first, then carry out edge sealing; apply adhesive or polyurethane coating if necessary.
4. Paving sequence: For connected roofs with different heights, construct high span first then low span. For the same roof, construct around drains, internal corners and special details first with reinforcement layer, then lay large-area waterproof membrane.

• Do not point torch or flame at people during construction.
• Do not carry out hot melt construction on windy days.
• Control flame distance and heating time to avoid overheating and damaging the membrane. The liquefied gas tank should be kept at least 20m away from the ignition point with dedicated staff on site.
• Avoid oil overflow when refueling the torch burner.
• Do not touch skin directly when using adhesive.
• Strictly prohibit open flame and smoking at material stacking area on construction site.
