Fire Retardant Spray Products

A fire retardant spray is a chemical that can be applied on porous surfaces to decrease the likelihood that they will ignite if exposed to flames. This can provide significant protection to people in situations where fires often occur. Many fire regulations require that a fire retardant spray product be applied in businesses like hotels, schools, trade shows, day care centers, and hospitals, etc.

By spraying exterior and interior surfaces with a fire retardant spray, you can get approval for your building from the Fire Marshal or Fire Inspector. In addition, you’ll have peace of mind, knowing that everyone in your building is protected, even in the unlikely event of a fire.

Fire retardant sprays for exterior wood and for interior wood are used for a variety of wood surfaces found inside and outside the structure. Treated wood will slow down a fire by not igniting easily. It’s important to use the product specified for the locations being protected.
