Review: Solid. Easy to use. And a little fun. - This stuff is awesome! And actually pretty fun. I used it to insulate a home-made keg cooler. I had a trash can, I built a wood frame around it, and filled the walls in between with this stuff. It is incredibly EASY!! Just mix equal parts of each ingredient in a disposable container, whip it together well and pour. The foam begins to form and rise immediately, and is rock solid in just a couple of minutes. If you’re debating if the 2 lb. kit is sturdy enough for your project, trust me, it’s really sturdy stuff when dry. I can barely dent it when I firmly poke it with a finger. I have no doubt the weight of the trash can full of ice and a sixtel keg will be solidly supported with this stuff around it. It also filled in around the 1/2” drain pipe in the bottom of the cooler no problem. I did it in small batches so that it wouldn’t overflow onto my floor, but I did overfill the space I needed just a bit. So all I had to do was take a small hand saw (a serrated knife would work fine) and trim the excess foam off. A little goes a long way, it only took a little over a half of the 1-gallon 2 lb. kit to fill my project (which is probably about right given the 4 cubic feet recommendation). Photos are are of the bottom of the cooler, before, and after filling and trimming.
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.
