SIS440 Caulk is the proven leader in the marine industry and was developed specifically for teak deck seams. 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 compound. The sealant does not sag during cure, and has excellent temperature stability and chemical resistance once cured. Because the sealant is neutral cure, it is non-corrosive to all substrates, will not damage the surrounding environment or structures, and provides minimum shrinkage. Caulk is easy to sand and will not clog sandpaper.
Store in a dry area at temperatures above 32°F (0°C) and below 80°F (26°C). Do not expose to direct sunlight, extreme heat, or freezing. The sealant has a shelf life of 18 months from manufacture date. See “BEST USED BY” date on packaging. Not designed for use under the waterline.
Other Applications:
- Bedding deck equipment/hardware
- Bedding parts (steps, pads, etc.)
- Caulk seams in other wood decks
- Edges around sealed windows
- Construction
