Min.Order:10 Square Meters
China National Petroleum Waterproof (Shenzhen) Co., Ltd.
1. Tackifying resin provides the membrane with strong adhesive strength which could make membranes stick to the base surface tightly.
2. The membrane has good puncture resistant, tear resistant and abrasive resistant property with the polyester as its reinforcement.
3. The membranes can be self healing for tiny cracks caused by environment.
4. Long-time stickiness assures no fall-off or any leakage between the membrane and the base surface.
5. The membrane has high tensile strength and good elongation property, it can maintain its shape even in the case of cracks and deformation on the base surface.
6. No dripping at high temperature and no cracks at low temperature.
7. Excellent chemical resistance, corrosion resistance and weathering resistance.
1, Interior roofs and underground construction.
2, Subways, tunnels, pools and water canals.
3, Waterproof projects which fire is not allow to be used.
4, Excellent for cold region due to its good low temperature flexibility.

1, The base surface must be checked and cleaned before paving in order to make it firm, clean and flat without any dust, oil and cracks.
2, Brush primer on the base surface evenly before paving.
3, Use blowtorch to help paving the parts which are hard to stick.
4, After the primer dry, pave the membrane from lower to higher. During the paving, fix one end of the membrane, and remove the isolation film, then pave it according to the line.
5, Vertical surface: stick membranes and the surface/membranes completely. For paving the end of membranes on the vertical surface, fix the end first, then seal it with membrane sealant or seal the end in the wall groove.
