Bitumen membrane ( known as APP / SBS) is more waterproof material currently used with hot melt coating method on a concrete roof, there are different grades . A little better construction quality , can control 3-4 years watertight ; almost , possibly leaking 3-4 months , but it can not find the leak repair more positions , many construction units last even for projects have not had.
Bitumen membrane roofing drawback : if water penetrates into the inner membrane, water everywhere channeling , to local repair , it is very difficult ; And if a problem exists or construction materials plant natural aging , have all eradication, clean base after re- waterproof surface , great price. And after MetaSeal Mesa roofing system for the liquid film class seamless construction, curing adhesive with a solid base surface , hydrophobic vapor permeability , there is some flexibility in the system flexible waterproof subsequent maintenance cost is almost zero, the price is very good .
Applications:
Overall maintenance of all types of old membrane roof renovation . Including APP / SBS, TPO, EPDM, self-adhesive membrane and other materials.
Features:
1 , environmentally friendly green products, construction on human health and the environment without harm ;
2 , with a strong crack resistance, with retractable cracks are flexible waterproof coating ;
3, the use of up to 15 years , 5-10 years, the quality of underwriting ;
4, green , excellent resistance to mildew algae performance ;
5, the overall waterproof, seamless construction ;
6 , simple construction , can brush or roller .
Construction program :
1, check and clean the painted area of the base surface , ensuring a solid base surface , smooth, without cracks, holes .
2 , first stir waterproof coating, slowly adding the corresponding proportion of grade cement , stirring constantly with an electric mixer to form a homogeneous group no uniform slurry . The prepared slurry should be used within four hours .
3, in the area of pre- coated with a slurry handled well , until when wet , the pre -cut waterproof polyester fabric embedded with a brush to catch level to ensure waterproof polyester fabric does not wrinkle , no bubbles . In the above painted a water slurry , full infiltration waterproof polyester fabric , and the whole dry ;
4,12 hours later, painted 1-2 Mesa Road water slurry or heat -reflective coating ( heat energy ) .
After a cold summer weather proof test : Roofing overall maintenance effect, completely solve the problem of water leakage , eliminating the worries of the owners get all the praise .
