It stays flexible after cure, bonds tenaciously to fiberglass, wood, metal, and glass, and stands up to years of flexing, UV exposure, and saltwater immersion without cracking or losing adhesion. Whether you are bedding deck hardware, sealing a thru-hull, glazing a port light, or re-caulking a teak deck seam, Life-Calk forms a long-lasting, watertight bond that can be sanded and painted once fully cured.\u003c\/p\u003e\u003cp\u003eThis line is offered in the tube and cartridge sizes boat owners actually need for jobs ranging from small hardware installs to full deck seam work, in the classic white and black colors used across most marine applications.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMaterial: Polysulfide, one-part liquid sealant\u003c\/li\u003e\n\u003cli\u003eColors: White, Black\u003c\/li\u003e\n\u003cli\u003ePackage formats: 2.8 oz tube, 5.2 oz cartridge, 10.6 oz cartridge\u003c\/li\u003e\n\u003cli\u003eCompatible surfaces: Fiberglass, glass, metal, wood\u003c\/li\u003e\n\u003cli\u003eWater resistance: Water resistant, suitable above and below the waterline\u003c\/li\u003e\n\u003cli\u003eCured sealant can be sanded and painted\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSizes \u0026amp; Options\u003c\/h3\u003e\u003cp\u003eChoose the 2.8 oz tube (BOA-1030) for small jobs like a single fitting, hinge, or fastener.
