What is caulk?

Caulk is a flexible sealant material used to fill and seal gaps or seams in various structures and piping. It is typically made from a combination of polymers, such as latex, rubber, or silicone, and is applied in a liquid form that cures into a rubber-like substance.

Caulk is commonly used to seal joints between different building components, such as walls, trim, windows, doors, and pipes. It helps to prevent water, air, dust, and insects from entering through these gaps, protecting the integrity of the structure and improving energy efficiency.
