Fortifiber offers Fortifiber Primer, a polymer emulsion based primer specially formulated to be compatible with all Fortifiber products.
The primer works with masonry, concrete, non-treated wood, drywall, metal and fiberglass mat gypsum board, including DensGlass®. It’s easily applied by brush, roller, or spray equipment and is specially formulated to provide a high level of tack on vertical surfaces.
Once applied, Fortifiber Primer quickly sets to a highly tacky film that provides increased adhesion for self-adhesive flashing membranes. It’s water-based, so there are no harsh solvents, and it’s non-flammable while wet. It also has low VOC content, at less than 50 grams per liter.
