More features

• Marine Flotation for Boats: This 2 lb density flotation foam adds lightweight buoyancy to nonstructural boat hull, deck, kayak and canoe cavities; each 2 Quart kit contains 32 fl oz of Part A plus 32 fl oz of Part B, yielding approximately 2 cu ft of expanded boat foam under recommended conditions
• 94% Closed Cell and Water Resistant: This marine grade expanding foam cures into rigid polyurethane foam with a 94% closed-cell structure to help limit water absorption; suitable as marine foam for damp hull and deck voids, including saltwater environments; not waterproof or a vessel safety system
• Pour-in-Place Void Filling: Starting as liquid foam, this pour foam reaches irregular spaces before expansion; useful for nonstructural void filling beneath decks and around insulated fish-box or bait-well surrounds; provides thermal insulation and sound dampening; allow space for expansion and pour larger fills in layers
• Easy 1:1 Mix by Volume: This 2 part foam requires equal volumes of Part A and Part B; measure carefully, mix thoroughly and pour immediately; foaming starts in approximately 45 seconds; verify surface compatibility and use proper ventilation
• Fast Expansion and Easy Trimming: Work at 75–80°F for optimal yield; temperatures below 75°F can reduce expansion; full expansion takes approximately 5 minutes under proper conditions; once fully cured, this two-part polyurethane foam can be cut, sanded and covered with compatible polyester, epoxy or vinyl ester resins
