TDS Teak Deck Caulking is a one-part, paste-like oxime cure system which when exposed to moisture in the air reacts to form a tough, flexible solid rubber compound. TDS Teak Deck Caulking is a thixotropic material that does not sag during cure and, when cured, has excellent temperature stability and chemical resistance. Because the sealant is neutral cure, it is non-corrosive to all substrates. TDS Teak Deck Caulking is available in black.
