All Purpose Sealant by Firestone
The Firestone All Purpose Sealant was designed as a single component polyurethane non-sag moisture-curing sealant.
The sealant can be use to caulk sheet metal, brick, masonry and concrete block.
One thing to keep in mind during application is that all preparation and cleaning should be finished before opening cartridges.
Comes in 10oz tubes.
