Mop Pro G is an SBS (Styrene-Butadiene-Styrene) modified bitumen roofing membrane reinforced with a polyester reinforcement that provides flexibility and dimensional stability as well as tear and puncture resistance. The proprietary SBS compound offers superb waterproofing and weathering physical properties. Mop Pro G is designed for use as cap sheet in multilayer low-slope assemblies. The membrane has a granular top surface in three color options and a sand bottom surface for hot asphalt or cold adhesive application methods.
Mop Pro G is intended to be used as the primary weathering surface in new or re-roof applications. Mop Pro G is to be applied as the uppermost layer of a multi-ply roof system applied over a compatible Hydraguard base or interply membrane. Mop Pro G may be applied directly to certain noncombustible substrates.
- Apply over clean, dry, dust and debris-free substrates. When fully bonding, prime concrete decks and required substrates, prior to application with PG 100 Fast-Drying Asphalt Primer or alternative ASTM D41 primers as approved by Polyglass.
- When re-roofing, remove all prior roofing materials down to a clean debris-free substrate and properly close-off all abandoned roof penetrations.
- Concrete or steel decks shall be designed with proper expansion devices.
- Wood decks shall have all joints blocked and properly supported.
- Ensure the fire rating of the assembly over any combustible substrate.
- Ensure the installation of Mop Pro G does not prevent the ventilation of existing construction.
- Do not apply over shingles or any granulated surface.
- While installing Mop Pro G:
- Start at the low point of the roof.
- Unroll the material and allow to relax then re-roll the membrane once relaxed.
- Install in a solid mopping of Type III or Type IV asphalt, PG 350 Mod Bit Adhesive.
- Position successive rolls providing a minimum 6″ end lap and 3″ side lap.
- Matching loose granules may be sprinkled onto the bleed out.
- Details and flashing may be installed using hot asphalt or cold application techniques. Check project details for proper installation requirements.
