          Description

          Teakdecking Systems® SIS-440 Teak Deck Caulking provides the durability boat owners require. It is a one-part, paste-like neutral cure formulation and when exposed to moisture in the air, it reacts to form a tough, flexible, solid rubber. SIS 440 Caulking was developed mainly for teak decking seams and provides better adhesion, longevity and appearance as compared to polysulfides, polyurethanes and MS polymers.

          Features:

          • Neutral-cure caulk reacts with atmospheric moisture to form a tough yet flexible, solid rubber compound
          • Does not sag during cure, adheres permanently and stays flexible
          • Cured sealant is non-corrosive to all substrates
          • Easy one-step application with no primer required
          • Highest-rated UV resistance
          • Outstanding temperature stability and chemical resistance

          Specifications:

          • Material: One-part polymer
          • Container: 10.3 oz. (305 ml) cartridge
          • Tack-free time: 20 - 40 minutes
          • Cure rime: 36 - 48 hours @ 68°F
          • Tensile strength: 300 psi

          Note: Tack-free and cure times are subject to atmospheric conditions

          Rated 5 out of 5 by from Teak Deck Systems Products and support I highly recommend SIS 440 Chaulk. I redid my 1997 Eastbay 40 FLybridge and my teak decking came out looking like new. Do not skimp when applying chaulk! I also used their tools and Teakdecking Systems Water Based Sealer and Protector. Call support if you have any questions!
