Product Characteristics
It has good waterproofing and ageing-resistance function,not flowing at highest temperature and no crack at lowest temperature;
Easy application,no pollution,and long service life etc.
Installation
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 fold,no falling away etc to guarantee the
waterproof life.
