Joint Materials


Sealants have a wide range of usages that demand different and unique performance characteristics. To ensure National Concrete Accessories has a product for your project, we carry a full line of silicone, polyurethane and latex based sealants and concrete caulking from the most trusted brands.

Common sealants used in construction are sealants for windows and doors that are designed to reduce the infiltration of gases, moisture and thermal transfer. These sealants are designed to be weatherproof, but flexible to allow for normal shifting within the structure.

A concrete joint sealant will allow movement, without transferring pressure, of the slab itself or the surrounding structures to prevent damage while remaining firm, flexible and providing a weather-tight seal. It is formulated to bridge the gap of a joint, and protect the expansion joint material from erosion.

We offer most of our concrete caulking and sealants in a variety of packaging sizes to keep your project on budget.
