Features & Benefits
- Labeling Claims
- 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.
