BoatLIFE Life-Calk Polysulfide Sealant Tube - Non-Shrinking Marine Sealant, Available in Black and White

BoatLIFE Life-Calk is a one-part polysulfide sealant built for the seams, joints, and hardware on your boat that need a flexible, long-lasting bond below and above the waterline. Formulated to stay non-shrinking as it cures, Life-Calk keeps a tight, consistent seal instead of pulling away from the joint over time, and it stands up to constant flexing, vibration, and water exposure without cracking or losing adhesion. It bonds well to fiberglass, glass, metal, plastic, rubber, and wood, making it a go-to choice for bedding deck hardware, sealing hull-to-deck joints, caulking teak decks, and general below-deck sealing tasks where a rigid or fast-curing sealant would fail.

Sizes & Options

Life-Calk is offered in two tube sizes and colors to match your job and the amount of coverage you need. The 2.8 fl oz tube in black is sized for larger sealing and bedding jobs where more material is needed, while the 1 fl oz tube in white suits smaller touch-up or trim work where a lighter, less noticeable seam is preferred. Choose your color based on the surrounding surface color and your volume based on the length and depth of the joint you are sealing.
