SIS-440 Teak Deck Caulking
SIS 440 caulking is our top selling product, and a proven leader in the marine industry. It is used by our team on every teak deck we manufacture. No primer is required for this one-part, paste-like neutral cure patented formulation, which when exposed to moisture in the air, reacts to form a tough, flexible solid rubber.This neutral cure is non-corrosive to all substrates. It provides the durability required in the marine environment and has excellent temperature stability and chemical resistance once cured.
Note: Material in a "unipak" sausage is viscous and often difficult to gun. Use of a 20 oz. air-powered dispensing system is strongly recommended. Both manual and pneumatic 20 oz. Dispenser Guns are also available and sold separately - SKU# WTDSSCG.
