Adheres to Wet Surfaces

Armour Proof AP-2400 Silicone Mastic is a one-part, high solids, low VOC silicone elastomeric flashing mastic specifically designed for use in sealing roof penetrations, seams, curbs, flashings and other areas on the roof where water infiltration is possible. It works well on roofs that were previously coated with AP-5200 Silicone Coating. Once cured, this liquid applied silicone mastic provides a durable, seamless, flexible, waterproof membrane that resists lateral movement, shear and will allow for normal expansion and contraction.

But what we’re most excited about is that we’re offering a solution to help you simplify your job site tool belt with a bulk caulk gun. These bulk caulk guns come with interchangeable plungers so that you can dispense our new 20oz. AP-2400 Silicone Mastic sausage tubes, our 10oz.
