Basic Uses & Description: Our FG 400 Flashing Grade Silicone Sealant is a thick, high-build liquid that resembles a rubber coating. It is a 100% silicone product specially formulated to possess very dense properties. It is designed to seal abnormal roof penetrations that cannot be covered with standard sprayers or rollers.
Because the product is so thick, it can stand in place of traditional rubber, mesh and polyester seam fabrics or tapes. Rather than laying down a roll of tape over separated seams, this product can be brush applied much more quickly and will be much stronger. It should be applied over the seam and then used in conjunction with our Pro-Eco Sil roof coating.
On top of seam sealing, FG 400 Flashing Grade Silicone Sealant is great for flashings, joints, small cracks, fasteners, vents, uneven surfaces, protrusions, drains and depressions.
Packaging Information: FG 400 Flashing Grade Silicone Sealant is available in 2 gallon pails.
