Description
The Problem Solver for Weathered, Cracking, and Peeling Paint
INSL-X® High Build Peel Bonding Primer (HE-5100) drastically shortens preparation labor on old, weathered surfaces where complete paint removal is impossible or cost-prohibitive. Rather than liquefying like standard thin primers, its heavy body acts as a liquid filler that flows into deep grain cracks, bridges the height difference between raw wood and remaining paint chips, and encapsulates fibers to seal out peeling-inducing moisture.
Best Used For:
• Weathered exterior wood clapboards, shingles, trim boards, and fences
• Rough interior/exterior masonry blocks, distressed stucco, and concrete walls
• Scraping-only repairs where old paint remains tightly bound but uneven
• Priming areas subject to dramatic structural shifts and moisture tension
Key Benefits & Features:
• Fiber-Lock Binding: Penetrates beneath micro-fractures in remaining old finishes, effectively gluing down loose margins to prevent future flaking.
• Labor-Saving Fill Layer: Fills physical surface voids in fewer steps, lowering the need for tedious wood skimming, filler putties, or excessive sanding.
• Outstanding Topcoat Anchor: Creates a tacky, rubberized clear matrix that holds latex or alkyd paint finishes firmly across decades of seasonal temperature spikes.
