Building sealant (commonly called “caulk”) is a versatile material used to fill gaps, joints, and cracks between building components in order to protect against water, air, insects, and a few other things.

It is used in a variety of weatherproofing applications including roofing, walls, windows, doors and concrete slabs to effectively prevent moisture intrusion as well as to improve energy efficiency. It can also play a role in soundproofing and fireproofing.

Building sealant comes in different colors and formulations based on the application needs and the type of substrate it’s being applied to.

Applying building sealant is fairly simple using either caulking guns or trowels.

Sealant is essential for building maintenance and helps to extend the lifespans of many building components by preventing water damage.
