Teakdecking Systems SIS-440 Teak Deck Caulking

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.

• 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
