Teakdecking Systems SIS-440 Teak Deck Caulking Item # 885744
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

The Best Thing For Teak
Using SIS 440 is the best thing you can do for your old and worn teak decking. The product is user friendly and finishes nicely. If you seal up the caulking tube with duct tape the remaining caulking is still usable for many days afterward. This make fixing little holidays in your work easier , and you don’t have to open another tube.

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!
