Seal trim and siding joints with DAP Alex Plus 10.1 oz. White Acrylic Latex Caulk Plus Silicone (Model 18103).
A silicone-modified acrylic latex caulk in a standard 10.1 oz. cartridge, formulated to fill joint gaps up to 1/2 inch without excessive sagging. The silicone modifiers give the cured bead enough elasticity to move with seasonal temperature swings instead of cracking, and the water-based formulation tools smoothly and cleans up with a wet rag. It cures to a crisp white finish that takes both latex and oil-based topcoats.
Performance Engineering
- Paint Ready in 30 Minutes: Accepts latex and oil-based coatings without staining or edge curling.
- Silicone-Modified Flexibility: Cured bead flexes with structural movement rather than tearing at the joint edge.
- Water Cleanup: Tools smooth and wipes away with a wet rag, no solvents required.
- Interior and Exterior Rated: Formulated to hold up to UV exposure, freeze-thaw cycling, and rain on exterior joints.
- Low Odor: Low-VOC cure suited to work in occupied interior spaces.
