BoatLIFE Life-Calk Marine Polysulfide Sealant & Bedding Compound
Life-Calk is a permanently flexible, polysulfide-based marine sealant and bedding compound trusted for decades on teak decks, through-hull fittings, and below-waterline seams. Unlike silicone-based sealants, polysulfide chemistry bonds tenaciously to wood, fiberglass, metal, and glass — and can be sanded, painted, and re-bedded without the adhesion failures common with silicone. It’s the professional’s choice for teak deck work and any application where long-term flexibility and fuel resistance are non-negotiable.
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
- 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
Compatible Applications
- Teak and laid-deck seam sealing
- Bedding deck hardware, cleats, and stanchion bases
- Through-hull fittings and underwater seams
- Keel bolt and rudder fitting seals
- Hull-to-deck joints on wooden and fiberglass boats
- Any application requiring a fuel-resistant, sandable, paintable flexible seal
Parts Desk Insights
Life-Calk is the right call when you’re working with teak decks or any fitting that will be exposed to fuel, teak oil, or needs to be sanded flush after bedding. Polysulfide is the traditional choice for teak seams because it stays flexible without bonding so aggressively that future removal becomes destructive. For non-teak applications where a faster-curing, high-strength bond is preferred, a polyurethane sealant like Sudbury 350 Marine Penetrating Sealant may be worth comparing. For smaller touch-up jobs on teak or hardware, the tube format of Life-Calk (if available in your catalog) is a practical companion.
