Why choose our marine foam products?
Our full selection of marine foams exceeds industry standards for resisting pressure and water penetration. Our boat foam products harden into shape with minimal reduction, resist mold and mildew, and have superior resilience and impact recovery.
Is this foam compliant with US Coast Guard regulations?
This foam has been tested in accordance with U.S. Coast Guard Regulation # 33 CFR 183.114 . This foam is approximately 95-98% closed cell which resists absorbing water, however continuous water submersion can eventually lead to loss of buoyancy over a period of years.
What is the temperature critical for foam expansion?
All expansion rates and times given are temperature critical. Temperatures below 75 degrees F will lower the expansion rate therefore requiring more foam. Ideal working temperature is 75 to 80 degrees F or above. Accurate measuring of these products is extremely critical.
How long does it take boat foam to expand?
This 2 part pour-in-place expanding polyurethane boat foam reaches full expansion in about five minutes, and can be poured in multiple layers with excellent bonding between layers. The cured foam hardens into shape with minimal shrinkage, is not affected by gas or oil, and resists mold and mildew.
What temperature should flotation foam be?
What is totalboat foam?
Can foam be laminated?
What foam is best for boat flotation?
Closed cell foam is an ideal product to use for buoyancy, and Versi-Foam® is one of the easiest closed cell foam kits to use for this purpose. A boat's job is to float. The US Coast Guard requires that all boats under 20 feet in length provide level flotation.
Can you use expanding foam in a boat?
You're Looking for Flotation Foam for Boats You want expanding foam for boats, and while the open cell spray foam we use expands, it's not a great fit. The thought is that you're trying to add structural integrity to the boat hull for example, if it gets hit by another boat or you hit a rock.
What is marine grade foam?
MARINE CLOSED CELL FOAM SHEETS They allow builders of recreational watercraft and yachts to replace wood components with top-quality, non-decaying marine polyurethane products for laminated fiberglass composite structures.

Does expandable foam absorb water?
Does spray foam absorb water? Yes, there are open cell spray foams on the market that will absorb water, but that doesn't mean they all do. The spray foam used here at RetroFoam of Michigan does get wet and water even moves through it, but it doesn't trap moisture indefinitely. This means it will dry out.

You want to fill the cavity until it's flush or slightly above a few low spots are okay but they should be.
Is Marine foam waterproof?
Marine Floatation Foam While some foam suppliers and boat manufacturers use spray foam for marine applications, there are better options. Closed-cell polyurethane foam is a waterproof, buoyant foam that also offers good insulation.
What type of foam does not absorb water?
Closed cell foamClosed cell foam is more impermeable to water, vapor, and air. Therefore, it is less likely to be structurally impacted by the effects associated with water damage: mold, mildew, rot, and bacteria.
What type of foam is waterproof?
It depends on the density of the foam. Open cell foam is not waterproof or water-resistant. In contrast, closed cell foam is water-resistant. However, only high-density closed cell foams are waterproof.
What is the last a foam?
LAST-A-FOAM® TR Marine foams are specifically formulated to meet the demanding requirements of the boating industry at a competitive price. They allow builders of recreational watercraft and yachts to replace wood components with top-quality, non-decaying marine polyurethane products for laminated fiberglass composite structures. Because our time-tested foams for boats do not absorb water, General Plastics’ marine polyurethane products do not rot, warp, bow or delaminate.
Does marine foam rot?
Because our time-tested foams for boats do not absorb water, General Plastics’ marine polyurethane products do not rot, warp, bow or delaminate. Our HDU marine-grade foam serves as core material for building transoms, hulls and bulkheads. It also provides an enduring, cost-effective choice for polyurethane boat interiors.

TotalPond Waterfall Foam Sealant, 12 oz
Waterfall Foam Sealant is a single-component polyurethane black foam that fills gaps and ensures efficient water flow over rocks.
What is EPS foam?
Often confused with STYROFOAM™ Brand Foam, EPS is lightweight and extremely buoyant, can be shaped and molded to fit the demand of marine construction and it holds up under year around environmental conditions.
What is Formex dock float made of?
Formex® dock floats are built using a rugged molded shell made from high density, high molecular weight polyethylene — a material which is also used for automotive gas tanks and canoes. The high tensile strength shell is resistant to impacts and is impermeable to water.
What is Formex made of?
The inside of the Formex® floats are made from top grade expanded polystyrene (EPS) foam that conforms and thermally fuses to the shell. A pre-molded solid foam block means there is no loose fill and minimizes voids that can fill with water, reducing buoyancy.
Is EPS floatation block waterproof?
It’s waterproof and if it’s punctured or damaged, your dock will continue to function. EPS is also environmentally friendly and its lightweight nature makes transport and assembly simple. EPS floatation blocks are supplied in an infinite number of sizes to accommodate your requirements.
Is EPS a good choice for a floating dock?
The marine environment can be tough: extreme temperatures, constant exposure to salt and water, and a demand for structures which can take a beating. If you’re building a floating dock, expanded polystyrene is an excellent economical choice. It’s waterproof and if it’s punctured or damaged, your dock will continue to function.
What temperature should flotation foam be?
Temperatures below 75°F will lower the expansion rate, which will require more flotation foam. WARNING: The 6 LB. Density Flotation Foam Activator can expose you to chemicals including ethylene glycol, which is known to the State of California to cause birth defects or other reproductive harm.
What is totalboat foam?
TotalBoat Marine Flotation Foam is great for filling voids, especially under decks. It’s thermal and sound-proofing abilities make it ideal for a number of other insulation and flotation applications. 94% closed-cell foam structure lets it maintains buoyant pressure even after prolonged exposure to water.
Can foam be laminated?
The cured foam hardens into shape with minimal shrinkage, is not affected by gas or oil, and resists mold and mildew. Once fully cured, foam can be laminated over with polyester, epoxy, or vinyl ester resins. Density: Available in 2 lb. or 6 lb. density foam.
