TotalBoat 2-Part Polyurethane Marine Flotation Foam

TotalBoat Marine Flotation Foam is great for filling voids, especially under decks. Its thermal and sound-proofing abilities make it ideal for a number of other insulation and flotation applications. 94% closed-cell foam structure lets it maintain buoyant pressure even after prolonged exposure to water.

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. Once fully cured, foam can be laminated over with polyester, epoxy, or vinyl ester resins.

We also have a 6lb density foam that has a higher compressive strength (is more dense) and is great for filling cavities to support heavy loads, for buoys and for carving or creating works of art.

Watching that stuff expand never gets old lol ;-)!!

Used this under my 18ft bowrider floor. Worked great.

Hi, is it possible to make a buoyant foam that can float in times of flood and can hold at least one person using PET plastic wastes added to FLOATATION FOAM CHEMICAL that you have shown in the video?

How accurate is the expansion volume listed? I just understand temperature plays a big part.

What if you poured each component into a dry/unused 1 gallon jug (picture a milk jug) and then covered the top (not screw that cap on, just held it on with your finger so any immediate pressure could release) and shook the container to mix?
I guess what I’m asking is, is it ok shake instead of stir. For mixing purposes. I feel like it would take less time and could potentially mix better?

[ZflashProductions]

What release agent do you recommend? I want to spray it on plastic but don't want it to stick necessarily.

Can I somehow mix this and pour through a narrow opening into an enclosed void, or do I have to completely open the top of the void first?

I have a 60 year old fiberglass boat, and the benches are closed voids meant for flotation should the craft be swamped. Each bench has a tunnel down through from front to back to allow water to flow to the stern at the center-line of the floor. I've discovered that the forward bench has tube that has deteriorated and allows water to easily get into that voice space.

I'm considering the relative merits of just adding more fiberglass to patch that, or potentially cutting a 2" hold in the top of the bench and using that to fill the void with foam, then glassing over that hole. So -- can I effectively fill at void of about 2 square feet through a two in hole?

When the foam expands to much and I have to shape it. How do I re-seal those sells of the foam?

[tsdrifter]

I would like to use this product for a very difficult to reach location. I anticipate drilling a hole and spraying the foam into the void to be filled. I know, I know - spray cans are already made for this. But they don't hold a ton of foam, I hate the waste & it stops being cost effective as the needed volume increases.
So, the question - If I mixed this up in a weed sprayer, gave it a stir & worked quickly, would you expect this to work?

You need to do one of two things. Stop selling this stuff for boats or tell people not to put it anywhere where it can have contact with water over time. read you own spec sheet! How long does coast guard test this stuff . 24 hours? 30 days???? Just tore 250 pounds of soaked foam out of my boat. you know this is common.
