Quality product for a fair price. 3M Fire Barrier Mortar meets the engineers specs for fire protection in most natural gas plants. The product arrived quickly, and applied well. We installed this product like a stucco coat around structural steel beams to give a 3 hour rated fire barrier. The customer is happy and that makes a contractor happy.
