Get the job done in a fraction of the time. This silicone-toughened acrylic composite forms a stable, skin-over barrier that is ready for paint coatings just 30 minutes after application.
Formulated with advanced anti-shrinking agents, this caulk maintains a permanently flexible, crack-proof bond line capable of handling structural expansion and contraction cycles for decades.
Engineered for the long haul: The Loctite Polyseamseal Acrylic Sealant System.
Take absolute command of your indoor trim work and outdoor weatherization projects with a commercial-grade adhesive caulk built for flawless performance. Packaged in a standard 10 fl. oz. rigid cartridge profile, this sealant dispenses smoothly and evenly from standard caulking guns. Its unique acrylic-silicone hybrid formulation provides the superior elastic adhesion of silicone paired with the painless, low-odor application and water clean-up of an acrylic base. It effortlessly fills cracks and expansion joints without shrinking, sagging, or wrinkling, drying to a clean, crisp finish that keeps outdoor moisture, drafts, and pests completely locked out.
Performance Features
- Flexible & Durable Matrix: Infused with elastic silicone modifiers that absorb structural shifts and household vibrations without tearing away from joint walls.
- Universal Substrate Adhesion: Forms a rock-solid, non-peeling bond on drywall sheets, bare or stained wood trim, masonry blocks, plaster, brick, and pre-painted surfaces.
- Effortless Water Clean-Up: No toxic chemical solvents or mineral spirits required; excess uncured caulk tools beautifully and washes off hands or tools with a simple damp cloth.
- Dual-Environment Resiliency: Specially formulated to resist weather weathering, UV fading, and moisture breakdown across both interior crown molding and exterior siding frames.
- Low-Shrink Control Technology: Cures evenly throughout the center of the joint, preventing the center-dimpling or edge-curling common to lower-grade latex compounds.
