Teakdecking Systems - 10oz Marine Caulk Cartridge, Gray - SIS440 - Premium Quality - for Teak Deck Seams - Provides First Class Appearance - UVChemical Resistant, Non-Corrosive.

SIS440 Caulk is the proven leader in the marine industry and was developed specifically for teak deck seams. It is a onepart, pastelike 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 noncorrosive to all substrates and will not damage the surrounding environment or structures. Caulk is easy to sand and will not clog sandpaper. Sanding with a fine 100 or 120 grit sandpaper is recommended. Gray caulk will shrink somewhat when applied. To avoid having low seams, it is recommended that 1 or 2mm extra caulking is left above a fresh seam. Store in a dry area at temperatures above 32F (0Cand below 80F (26C. 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.
