Seal interior trim and exterior joints with Loctite Polyseamseal 10 oz. White Acrylic Caulk with Silicone.
A silicone-modified acrylic latex sealant in a standard 10 fl. oz. cartridge that dispenses smoothly from any common caulking gun. The hybrid formulation pairs the flexibility of silicone with the low odor, easy tooling, and water cleanup of an acrylic base. It fills cracks and expansion joints without sagging or wrinkling and dries to a clean white finish that takes paint.
Performance Engineering
- Paint Ready in 30 Minutes: Skins over quickly so you can move from caulking to painting in the same visit.
- Flexible Silicone-Modified Matrix: Stays pliable through seasonal movement instead of tearing away from the joint walls.
- Broad Substrate Adhesion: Bonds to drywall, bare or stained wood trim, masonry, plaster, brick, and previously painted surfaces.
- Water Cleanup: Uncured material tools easily and washes off hands and tools with a damp cloth, no solvents needed.
- Low-Shrink Cure: Cures evenly through the joint to avoid the center-dimpling common to lower-grade latex compounds.
