LULU SBS modified bitumen membrane is a kind of flexible sheet waterproof which uses Styrene Butadiene Styrene/SBS thermoplastic rubber as a dipping and covering modifier, whose upper surface is coated by PE film, fine sand, mineralgrain or aluminum foil or other isolating materials. The compound is a mixture of distilled bitumen, plastomers and stomers which gives the membrane excellent resistance to heat aging and weathering.
2. Product Features
Integrated advantage properties of spunbonded polyester substrates and SBS modified asphalt, wonderful integrated properties.
High strength and good property to stand against water pressure
High tensile strength and elongation rate, strong adaptability for substrat shrinking distortion and cracks
Good construction performance, with firm and enduring joints
1) Make sure the roof deck smooth,clean and dry(Moisture<9%),then apply the surface of roof deck homogeneously with a kind bitumen paint till dry to start application.
2) There are two methods in application:
One way is by heating and melting method---Heat the polyethylene film of the membrane and roof deck surface by heating and melting method to be nearly melted(not flowing),then install the membrane fully bonded to the roof deck with overlaps of 5-10cm.
The other way is by cold adhesive method---Pour the cold adhesive homogeneously on the roof deck then roll the membrane to install it to be fully sticked to roof deck.By heating and
melting method and by cold adhesive can be used in alternation in application as requested.
3) After application,a full serious inspection is required to make sure no air bubble,no old,no falling away etc to guarantee the waterproof life
