1)     Base processing: the base surface must be clean, solid, level, dry; no grit, rift and loosing dust. For a large recess, fill it with cement mortar and then level it. Remove the protrusion and clean dust. If working on base slab or lateral face, water lowering should be done.

2)     Painting primer: before laying the membrane, clean the dust on the surface of concrete base with dust catcher or dust-blower.

3)     Heat to melt: place membrane correctly, fire torch, heat the membrane with base entirely, when the surface of the membrane is black and bright with a fusion layer, apply the membrane and press it into a solid and flat state. Before the membrane is cool, seal the edge of joint by float.

4)     Requirements for lapping: There should be less than 3 layers of lapping, with the joint seams appearing as "T" type, avoid 4 layers of lapping. The width of longitudinal lapping is between 50 and 80mm, and of end-lap joint 100mm.
