Exterior caulking is applied to seal gaps, joints, and cracks in various outdoor surfaces.
It prevents water infiltration, air leals, and insect penetration, contributing to energy efficiency and structural integrity.

Common caulking materials for exterior applications include silicone, polyurethane, and latex-based caulks.

Some caulks are specifically designed for certain surfaces, such as wood, metal, concrete, or masonry.

Caulk is applied using a caulking gun and is dispensed along joints, seams or gaps.
