Foster® MAST-A-FAB® WHITE Reinforcing Membrane 42-24

1 of 92 products in this brand
Foster® MAST-A-FAB® WHITE Reinforcing Membrane 42-24 features a synthetic fiber composition that offers enhanced elongation, recovery, and resistance to stress breakage. This membrane's leno weave design ensures fabric stability, eliminating the typical thread movement and distortion found in plain weave cloths. Importantly, it has no discernible impact on the flame spread and smoke-developed ratings of the chosen mastic or coating.

Product Highlights
  • MAST-A-FAB® is easy to bond to and wets out readily compared to glass cloth. This minimizes the possibility of the disbonding of tack and finish coats, a common problem with glass membrane reinforcement.
  • Because it weighs only 1.3 ounces per square yard, about half the weight of glass cloth, Mast-a-Fab® is easy to work with. A full roll can easily be "one handed" for a faster, trouble free installation.
  • MAST-A-FAB® contains no asbestos, lead, mercury, or mercury compounds.
