White Lightning Flame Buster Intumescent Latex Caulk (Carton of 12)

Description

The White Lightning Flame Buster Intumescent Latex Caulk is an elastomeric, intumescent sealant for use on or around wires, pipes, ducts and vents. When exposed to extreme heat it expands, forming an insulated char. This will prevent the spread of smoke, fire and toxic gases and is great for adhesion to almost any surface, both interior and exterior. It will remain flexible and can be painted after inspection.
