What is Caulking?

Caulking is the process of applying a sealant material, called caulk, to gaps, cracks, or seams in various surfaces. It's used to seal joints and prevent air, water, or dust from entering or escaping. Caulk is commonly used around windows, doors, bathtubs, sinks, and baseboards, as well as in construction and home improvement projects to improve insulation and prevent leaks. The caulk itself is typically made of materials like silicone, latex, or polyurethane, depending on the surface and the type of seal needed.
