1. Make sure the roof deck smooth, 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 filly 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 sure no air bubble, no falling away. etc. To guarantee the waterproof life.
