BoatLIFE Life-Calk Marine Polysulfide Sealant & Bedding Compound – 10 oz. Cartridge, White
Life-Calk in white — the same permanently flexible polysulfide formula trusted for teak decks, through-hull fittings, and below-waterline seams, in a 10 oz. cartridge sized for larger jobs. The white finish makes it the right choice for white hulls, gelcoat surfaces, and bright-finish hardware where a black or clear bead would stand out. Unlike silicone, polysulfide can be sanded, painted, and re-bedded cleanly — making it the professional standard for teak work and fuel-exposed fittings.
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
- Standard 10 oz. cartridge — fits any standard caulk gun
- Cleanup with mineral spirits
Compatible Applications
- Teak and laid-deck seam sealing on white or light-colored decks
- Bedding deck hardware, cleats, and stanchion bases on white hulls
- Through-hull fittings and underwater seams on gelcoat surfaces
- Keel bolt and rudder fitting seals where color match matters
- Hull-to-deck joints on white fiberglass boats
- Any large-area sealing project requiring a fuel-resistant, sandable, white flexible seal
Parts Desk Insights
The white cartridge is the go-to Life-Calk for white-hull boats and gelcoat decks where a black bead would be visible and unwanted. The 10 oz. cartridge format is the practical choice for continuous runs, full teak seaming, and production bedding work. For smaller touch-up jobs or when you don’t want to break out a caulk gun, the Life-Calk 1 oz. Tube is a handy companion. Need a black finish for dark hulls? See the Life-Calk 10 oz. Cartridge, Black. For non-teak applications where a faster-curing bond is preferred, see the Sudbury 300 Marine Sealant – White, 10 oz. Cartridge.
