  • EASY TO USE: Liquid urethane pour foam has a simple 1:1 mix ratio, expands rapidly & hardens in place in about 5 min. at 70-80F; to build multiple layers for filling under boat decks, pour expanding foam in separate batches

Description

Be safer and more comfortable on your boat with Total Boat Two Part Polyurethane Marine Expanding Foam. This US Coast Guard compliant pour foam is commonly used to add buoyancy to keep a boat afloat if hull integrity is compromised. Its closed cell foam structure enables it to resist water absorption for many years, making it ideal for filling pontoons and cavities in kayaks and beneath boat decks. 2 Lb. density expanding urethane foam kit mixes to form a fast-setting, pourable liquid foam that cures to a rigid, lightweight material that's also great for filling gaps, soundproofing, and providing thermal foam insulation and nonstructural support in a variety of marine, household and art applications. Two part flotation foam has a simple 1:1 mix ratio that makes it easy to use. Warm conditions of 75-85°F are very important, as are accurate measuring, thorough mixing, and proper venting of the area where the foam is to be applied, because it expands tremendously by volume. Just mix one part resin and one part activator, stir vigorously for about 25 seconds to mix completely and pour immediately into the prepared area. Expanding foam will distribute itself evenly - even into irregularly shaped areas. Cured foam hardens into shape, with minimal shrinkage, and can be cut to shape easily. Once fully cured, any areas exposed to sunlight should be laminated or painted over with polyester, epoxy or vinyl ester coatings. For best results filling larger areas, pour in multiple layers to allow proper cure and maximum strength bonding between layers. Always wear proper eye, face and clothing protection when you mix and pour two part marine foam. Compare to Evercoat Marine Foam-It, FGCI Polyurethane Foam, Polymer Planet Liquid Urethane Foam, Morris Materials Urethane Pour Foam, True Composites Pour Foam, and System Three Flotation Foam for boats. All TotalBoat products provide great value and great results. 100% made in the USA.

  • Trial and Error, Read the directions first. I did and still has a learning curve.
Size: 2 Gallon Kit
Applying concoction into sit on top kayak Started out not liking it much. It's early November in Central Texas and the outside temperature was around 80 degrees, the sun was out and warm. The cans were stored in my shed, and the temperature of the resin and activator were probably around 50 degrees. I mixed up a little bit of this stuff into a wash basin and put it in my kayak. The stuff didn't really foam up. Realization: Just because the outside temperature is 80 degrees still does not mean that the foam will work. I found a pot large enough to put one can in at a time (wife was watching TV at the time :). Light up the stove top and bring the temperature of the resin and activator to around 80 degrees (shake in a circular motion to mix hot and cold, I had to put on the stove 3 times per can). I used my hands to measure the temperature. Nothing scientific. I screwed off the top of the foam can and had to poor it quick... It was trying to foam up. I used a wash basin to mix the 2 together. Don gloves, this stuff adheres to everything and is difficult to remove. Ensure that the hole that you are putting this stuff into is fairly large (Mine is almost the size of my head and still got this stuff all over my kayak.) It worked ok at first, but after the first batch started to heat up the inside of my kayak the rest of the stuff worked like a charm. It filled up the whole back end of my 2 person kayak. After it's done foaming it turns hard. I can still scrape it with my fingernail. But, for filling the void and stabilizing the outside hull, it did a superb job. I just bought a second batch to fill up the front end of my boat. I hope this helps.... happy foaming :) Second purchase I didn't have to heat up since I left it out in the sun. Kayak was in the sun as well and this stuff worked great. I mixed up a little at a time, and then pour it in. This time after the pouring in 2-3 batches I took the kayak off the shed it was leaned up against and turned it topside down to spread the foam all over. It still worked great but got some on my hands this time... they turned black. I rubbed them against a brick wall and the blackness deteriorated. Not completely gone but it's not as prevalent. ... show more

  • Great for all kinds of jobs. Follow directions / Read some reviews before using though.
Size: 2 Gallon Kit
This expanding foam is really useful for me in multiple jobs / hobbies. I build molds and use it to pour faux stone / rock panels which I then use in home remodels, building, etc... It can actually be used to create molds as well. I also build fiberglass / carbon fiber panels for automotive projects and use this foam to pull positives off of simple parts like fenders and other flat-ish stuff. The key to working with this product is to be prepared. Use acetone to clean. Have mixing cups, rags, gloves, tape, painter's plastic, mold release, etc... When it is in liquid form it's very thin and will easily escape through small cracks, so be sure to seal molds up well to minimize loss and mess. Caulking works well. As everyone says, it works very quickly once mixed. Heating the product up will make it take off even quicker, and it will also increase the yield significantly. I, personally use a heat gun on low from a distance to heat each cup before mixing. Lastly, don't disturb it when it is beginning to harden and take shape. Doing so will cause it to "deflate" in that area, kind of stunting its growth. Follow directions and read some other reviews for insights and tips. You'll be pro in no time. ... show more

  • This stuff is AWESOME!
Size: 2 Gallon Kit
Want to feel like a scientist!? For real, this floatation foam blew away my expectations. I was building a custom boat, and so I decided to use flotation foam for the bow of the boat. I was shocked at how much it expanded and how easy it was to use and pour. Now it's got me thinking of what else I could use it for! Great product, great company! ... show more

  • Awesome foam for your boat.
Size: 2 Gallon Kit
The 2 lb density foam works great. It was easy to mix and pour into my boat floor. It filled everything very well and was not hard to shave down even with the top of the floor. It is extremely solid foam and makes the floor extremely solid. I could walk on top of the foam with no give to it at all. I also like that this foam will not obsorb water and actually repels it. My floor in my boat is better and stronger now than when the boat was new. ... show more
