White & Grey Caulk

TDS's white and grey caulk lines offer the same marine-grade durability as our classic black caulk. This guide covers application technique and colour-matching tips for light-coloured decks — including how to choose between white and grey based on plank colour and deck style, how to achieve a clean seam without visible tape lines, and curing guidance for light caulk colours.

White and grey SIS 440 caulk is particularly popular on vessels with lighter teak, composite decks in natural or light tones, and interior deck applications. The formulation and performance characteristics are identical to black SIS 440 — only the pigment changes. See the SIS 440 product page for available sizes and colour options.
