Lifeboat Urethane Pour Foam - 2lb Density - 2 Gallon Kit 2-Part Closed Cell Rigid Pour Foam - Fast-Acting Formula - Great for Boat Buoyancy, Flotation, Filling, Soundproofing, & Insulation

It worked well. Both in purpose and ease of use. You need to make sure it is measured right 1:1 and mixed thoroughly. I put a 3/8” wood dowel in my drill and put a couple zip ties on the end to make a power stirrer. This worked great. I would measure, combine and mix with the drill, taking a few seconds after mixing each time spin the mixer in acetone to clean.Don’t clean up drips or the vent blow outs till they are hard. It’s less work that way.

I purchased this for a project at our cabin but that didn't work out, so it was just sitting in our garage. I installed a new yard light and needed to secure the pole in the hole. I had heard about using foam so I thought I'd give it a try. My hole was 18" deep and about 7" wide. I mixed up about 2 cups of this and poured it in. Wow! It filled the hole and bulged out of the ground. This stuff is tough, and also difficult to remove from anything that it cures on. As a result, the post is secure and I am delighted with the result.

Filling gaps and hole’s made easy!

Bottles were sealed perfectly when I received them. They mixed great and expanded as good or better than a more expensive foam I bought elsewhere.

I bought this product for a project boat and received it earlier in a well packed box.

Used this Floatation Foam to restore a 1986 Sea Nymph Striper CC 17. Needed to replace the two rear foam pockets between the splashguard and transom. Cleaned out the space and sealed all corners using duck tape (ceiling/void expansion will work as well). Just make sure every pocket is covered as this will seep into the smallest spaces. Mixed half of the 2 gallon (1 gallon from each bottle) into the bucket, used a long metal mixer with my drill and mixed it for up to a minute as the contents will start to do a chemical reaction start pouring into the desire space as soon as possible and dont be afraid to add a little extra vs using less as you may have to add more on top of the previous pour and it will not look good in unison. Its that easy. Look at a few youtube videos on 2 part polyurethane pours or floatation foam. You will understand why prepping is very important and you will get it right the first time. Not intimidating at allP.S it is a chemically reactive so wear gloves or your skin may burn

Works as described. Just be sure product is up to temperature

Other than the fast reaction time, this product works well. We mixed up 6 cup batches (3 cups of each part) using a homemade spiral wire stirring whip. We lined a 3 lb. coffee can with 1 gallon ziplock freezer bags for the mixing container which greatly minimized the mess and cleanup. We also started each session about 5 degrees lower than the recommended temperature and seemed to get a good expansion rate. It took six sessions to fill 24 55 gal. plastic drums.
