Caulking

Caulking is a material used to seal gaps and cracks in buildings to prevent air, water, and pests from entering or escaping. It is typically a flexible substance, often silicone or latex-based, that is applied with a caulking gun or similar tool. Once dried or cured, it creates a weatherproof barrier, improving energy efficiency and protecting structures from damage. Caulking is commonly used around windows, doors, and joints in walls, ensuring a secure and insulated environment while maintaining the building's appearance.
