Scope of application

1.Applicable to industrial and civil construction roofing, underground and other waterproof moisture-proof and bridges, car parks, swimming pools, tunnels and other building waterproof.

2.Applicable to high temperature or strong solar radiation area of the building waterproof, according to our country the technical code for roof engineering GB5020794, APP plastic modification asphalt waterproof coiled material, can be used for a particularly important civil construction and water have the special requirements of industrial building.

  

Attentions for Construction

Construction shall not be carried out in rain, snow or over 5 degree wind weather; Thereshall be sufficient safety protective facilities in construction site, place firefighting devices according to stipulations.

1)Clean the substrate using broom or high pressure dusty cleaner.

2)Apply primer.

3)Heat the membrane bottom using a high temperature flame gun.

4)Push forward while the primer and membrane oil melted.

5)Use a roller to push hard the membrane surface to ensure it stick firmly.
