## Description

True Composites 2lb Boat Pour Foam Kit, 1 Gallon | Closed-cell foam for flotation, insulation, filling & buoyancy.: desertcart.com: Industrial & Scientific

Review: Worked well fixing hole in boat. - This stuff did a great job. I had a crack in the hull of my boat. I cut a hole in a compartment above the leak and dug down through the foam to repair the leak. The hole I made was about 10” x 10” x 24”. When the leak was repaired I read the instructions (hope I don’t loose my man card), Then mixed enough for 2 cubic feet. It not only filled the but mushroomed our the top. It was easy to remove the excess and cut the foam slightly below the floor. The fiberglass laid over the foam with no issues and was easy to finish and gel coat. Great product.
Review: Works great in silicon mold prop making! - I have a project in which I need many, and I mean MANY foam skulls. I decided to try my hand at making a silicone mold of a simple skull and using this urethane to make my skulls. SUPER ECONOMICAL this way. Not too much of a learning curve either! Didn’t need mold release just mix, pour, slosh it around a little and wait 15-30 minutes to demold. Worked like a charm! Update - finally through the first set of bottles that I ordered. My skulls vary from needing 3-5 mixed ounces of product (1.5-2.5 oz each A&B) and I was able to make a total of 29 skulls and 2 small jaws. This was my first time making molds and working with a 2 part foam. Considering the learning curve I expect to get 35-40 skulls out of the next set of bottles as I have a better grip on how to reduce waste and how much product to use in which mold. I also found that leaving the foam in the mold over night lead to greater detail, less shrinkage and a better skinned surface. Also a little easier to demold.
