Surface Preparation
All surfaces must be clean, dry, free from voids, curing compounds, loose or flaking materials, oil, grease, and surface coatings, and must be structurally sound before applying Boscoseal PUR. The interface between metal flashing and concrete may be sealed with Boscoseal PUR, reinforced by embedding a wide strip of fiberglass.
All non-moving structural shrinkage cracks less than 2 mm wide must be pretreated with Boscoseal PUR membrane extending at least 100 mm on each side of the crack.
Cracks and joints measuring 2 mm or wider must be sealed with Bostik Seal N Flex 1 PU sealant.
