BoatLIFE Life-Calk Marine Polysulfide Sealant & Bedding Compound – White
Life-Calk in white — the same permanently flexible polysulfide formula trusted for teak decks, through-hull fittings, and below-waterline seams, in a white finish that blends with white hulls, gelcoat surfaces, and bright-finish hardware. Polysulfide chemistry bonds tenaciously to wood, fiberglass, metal, and glass, and unlike silicone, it can be sanded, painted, and re-bedded cleanly without adhesion failures.
Key Features
- Permanently flexible polysulfide formula — will not crack or harden over time
- Tack-free in 1–3 days; full cure delivers a firm, rubber-like seal
- White finish — blends with white hulls, gelcoat, and bright-finish hardware
- Excellent resistance to teak oils, gasoline, and diesel fuel
- Can be sanded and painted after cure
- Bonds to fiberglass, wood, metal, glass, and itself
- Suitable for above- and below-waterline use
- Can be applied underwater for emergency repairs
- Cleanup with mineral spirits
Compatible Applications
- Hardware bedding on white or gelcoat hulls and decks
- Portlights, hatches, and trim on white-finish boats
- Through-hull fittings and underwater seams on light-colored surfaces
- Teak deck hardware bedding where a white finish is preferred
- Touch-up and small-area sealing on white hulls requiring a fuel-resistant, sandable polysulfide bond
Parts Desk Insights
The white Life-Calk is the right call for white-hull boats and gelcoat decks where polysulfide chemistry is needed but a black or teak bead would stand out. For larger white-hull sealing projects requiring a full cartridge, see the Life-Calk 10 oz. Cartridge, White. For other color options in this format, see the Life-Calk Clear or the Life-Calk Teak Cartridge. For smaller touch-up jobs, the Life-Calk 1 oz. Tube is a handy companion. Always prep surfaces with BoatLIFE Release before applying fresh sealant for best adhesion.
