Maxshield 300S is an atatic polypropylene plastomeric (APP) modified bitumen waterproof sheet membrane. It is formulated from high grade modified bitumen with selected elastic polymer and reinforced with non woven polyester reinforcement. The membrane provides good elongation, high puncture resistance and good mechanical characteristic. The membrane is top coated by sand or polyethylene (PE) and bottom surface protected by heat sensitive film.
AREA OF USES
APPLICATION AND INSTALLATION
Concrete substrate must be at least 28 days old. Substrate must be sound, smooth, clean, dry and free from loose materials, oil, grease or any other contaminants. In case of substrate has moisture on surface use flame torch to dry up surface prior to apply primer.
Apply Maxshield Primer on prepared substrate at approximate coverage rate 5m2 per litre and allow to dry.
Maxshield 300S should be install using gas torch. Slowly unrolled the membrane and flame torch the membrane until the bottom surface melt but do not over heat. Side overlap must be minimum 150mm. roll overlap joint must be minimum 100mm. Lap joint should be sealed by torch. All expansion joints, movement joints and all joints must be followed and allowed follow structural design. Other joints and end points must be allowed according to specifications. The membrane must be protected immediately after installation.
Maxshield 300S must be installed by experiences, trained and approved applicators. Installation shall be strictly in accordance with manufacture method statement instruction.
