BoatLIFE Life-Calk Marine Polysulfide Sealant & Bedding Compound – 10 oz. Cartridge, Clear
Life-Calk in clear — the same permanently flexible polysulfide formula trusted for teak decks, through-hull fittings, and below-waterline seams, in a 10 oz. cartridge with a virtually invisible finish. The clear formulation works on any hull color and is the right choice when you need a watertight, fuel-resistant polysulfide bond without a visible bead. Unlike silicone, it can be sanded, painted, and re-bedded cleanly.
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
- Clear finish — virtually invisible once cured, works on any hull color
- 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
- Hardware bedding on multi-color or bright-finish hulls and decks
- Portlights, hatches, and windows where a clear polysulfide seal is preferred
- Through-hull fittings and underwater seams on any hull color
- Teak deck hardware bedding where color match isn’t critical
- Any large-area sealing project requiring a fuel-resistant, sandable, invisible polysulfide bond
Parts Desk Insights
The clear cartridge is the most versatile color in the Life-Calk lineup — it works on any hull color and is the go-to when you want polysulfide chemistry without committing to a black, white, or teak bead. It’s particularly useful for mixed-color decks or hardware where color-matching is difficult. For color-specific applications, see the Life-Calk Teak Cartridge, Life-Calk White Cartridge, or Life-Calk Black 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.
