White Lightning Flame Buster® Intumescent Latex Caulk 10 oz Red

White Lightning® FlameBuster™ Intumescent Latex Sealant is a one part, elastomeric, intumescent sealant that expands when exposed to fire or extreme heat, forming an insulated char. Flamebuster Intumescent Latex will prevent the spread of toxic gases, smoke and fire. It is suitable for adhesion to almost any surface and remains flexible, making it ideal for both horizontal and vertical joints, subject to vibration or dynamic movement. Flamebuster Intumescent Latex can be used for interior or exterior applications, and can be painted (after inspection).
