Description
itis a modified bitumen base sheet consisting of polymer modified asphalt added viscosifier inside covering with different upper separated materials and underside with silicone antisticking layer. According to different upper surface, it includes three types: PE film surfacing (SAM-930APE), sand surfacing (SAM-930AS) and antisticking surfacing (SAM-930AN). There have two kinds of thickness: 3.0 mm and 4.0 mm.

Surface Preparation
Surfaces should be dry, clean, smooth and free from any dusts, oil or loose particles. Cracks and uneven places need to be filled by polymer mortar.
Priming
Before membrane laying, substrate treating agent need to be brushed evenly and completely cover all laying places.
Membrane laying
After substrate treating agent drying, lay SAM-930A material according to application designs.
Sealing, fixing and constraining on vertical surfaces
On vertical surfaces, fix with metal battens and seal with sealants for membranes.
