SBS modified bitumen waterproof roof membrane

الوصف

Main Feature
(1) Good waterproof performance.
(2) High tensile strength, large elongation, good tear resistance, high impact resistance, dimensional stability, excellent puncture resistance, weather resistance, and corrosion resistance.
(3) Anti-corrosion, mildew resistant and weather resistant.
(4) Hot melt construction, solid and long-lasting.
Construction Method China *6 years experience SBS modified bitumen waterproof roof membrane: Primary treatment →Preparation of polymer cement slurry →joint processing →coil paving →closed head coil processing →waterproof layer acceptance →protective layer construction. Basic requirements: 
(1)Before application, the substrate must be free of any dust, dirt, oils, snow, ice, water and debris that could interfere with proper adhesion,the surface must be smooth and hard. (2)The primary treatment agent must be applied before construction.
Method:
(1)Heating and melting method: Use flame gun or other tool to heat evenly in the bottom layer of membrane , when the bitumen begins to melt and presents to be black and light, roast and pave and paste the membrane. (2)Cold alhesion method：apply adhesive or mastics between the membrane and substrate or membrane. (3)Checking and acceptance: a thorough inspection is required after application to insure there is no air bubble, no falling away and etc. to guarantee the waterproof life.
