Need serious fire protection for your home or building? This Adhesive Guru AG510 sealant is the stuff. It's a fire-block caulk that can resist fire for up to 4 hours in a rated assembly, which is a huge deal for safety. It's intumescent, meaning it expands when exposed to heat to seal off gaps and stop fire, smoke, and toxic gases from spreading. It can handle temperatures up to 2000°F and reduces heat transfer. It's water-based, so you apply it with a standard caulking gun and clean up with water – no special chemicals needed. Use it to seal around pipes, ducts, electrical penetrations, chimney gaps, and in construction joints. It's non-flammable and halogen-free. This listing is for a bulk pack of 24 tubes, each 10.5 fluid ounces. Perfect for contractors, builders, or serious DIYers doing fire safety upgrades. Made in Türkiye. Follow installation guidelines for proper fire-rated performance.
