Teak Deck Caulks Rated for Durability and Resistance to Chemicals

Teakdecking Systems teak caulk stands the test of time—and multiple chemical baths.

Seven caulks were applied to teak-deck seams in June 2006. At that time Practical Sailor looked at ease of application, adhesion, durability, and resistance to chemicals. Updates in the September 2006 and March 2007 issues looked at pliability, durability, and adhesion. This update tests caulks for long-term durability and resistance to chemicals. A 4-inch bead of each teak caulk that was applied two years ago to 16 different panels was doused regularly with chemicals that teak decks are likely to be exposed to (motor oil, acetone, nleach, etc.). The test group is a mix of polysulfide, polyether, silyl modified polymer (SMP), and silicone-based products. Seven products were tested: Boatlife Life Caulk; BoatLIFE Teak Deck Sealant; BoatLIFE Type P; Bostik/Simson MSR; Teakdecking Systems; MARITIME Teak Deck Caulk, and West Marine Multi-Caulk.
