BoatLife Life-Calk Marine Sealant — White | 30ml / 1oz Tube | BOA-1305
BoatLife Life-Calk is one of the marine industry’s most trusted polysulfide-based sealants, engineered specifically for below- and above-waterline applications on boats and ships. This compact 30ml / 1oz tube delivers professional-grade sealing performance in a convenient size — ideal for targeted repairs, touch-ups, and small sealing jobs where precision matters.
Key Features
- Polysulfide formula — remains permanently flexible after curing, accommodating the constant movement and vibration of a working vessel without cracking or losing adhesion
- Above & below waterline rated — suitable for sealing deck hardware, portlights, through-hulls, keel bolts, and hull fittings both above and below the waterline
- Excellent adhesion — bonds tenaciously to fibreglass, wood, metal, and most marine substrates
- White finish — clean, professional appearance that blends with white decks, hulls, and topsides
- Fuel and oil resistant — polysulfide chemistry resists degradation from fuel, oil, and bilge water exposure
- Compact 30ml tube — easy to apply with precision; no caulking gun required
Ideal For
Sealing deck hardware, stanchion bases, cleats, portlights, hatches, through-hull fittings, and any penetration requiring a durable, watertight, flexible seal. The 1oz tube size is perfect for targeted repairs and maintenance jobs without the waste of a full cartridge.
Application Notes
- Clean and degrease all surfaces before application for maximum adhesion
- Mask surrounding areas for a clean finish
- Allow full cure time before immersion — typically 5–7 days depending on temperature and humidity
- Not recommended for use with polycarbonate (Lexan) or acrylic (Plexiglas) surfaces — use a neutral-cure silicone instead
