SMARTFAB™ 500 Reinforcement (Heavy Soft) (Tietex T272 or Equal) is a stitchbonded polyester fabric valued for strength when used as a reinforcement in SMARTCOAT™ liquid applied roofing systems. This product is also used as a flashing or repair reinforcement with SMARTCOAT SmartFlash® ONE. SMARTFAB 500 has superior strength and elongation properties, resulting in excellent resilience to stress caused by rooftop thermal expansion and contraction. SMARTFAB 500 provides good conformability on smooth or semi-smooth surfaces such as cap sheet, smooth surface and filled or spudded gravel, and irregular shapes.

This product has a close knit, which may require light brooming to insure good embedment and removal of any air pockets. It is recommended for flashing details, as compared to SMARTFAB 501 which is recommended for field reinforcement.

SMARTFAB 500 is available in 4”, 6”, 12” and 20” widths, each roll is 300’ long. SMARTFAB 500 is sold in cartons of five rolls each.
