Smooth-On FlexFoam-iT!™ III Flexible Urethane Foam, Casting Foam for Props, Gaskets, & More - Pint Unit

Nice and soft and tough. I've never used this before and it came out so well. Was like a soft mattress topper feel.

Came fast, works great and exactly as described.

So my 9 yr old is all about squishies. This product was very very easy to use. However I will warn u. Def wear gloves. And don't let it get on counters, sinks etc. very hard to remove. Also I saw in other reviews to get quick release. I didn't get that and it was very hard to get out of silicone molds. Also when we did it in a plastic container or cup it didn't stick as bad and bottom came out much smoother then silicone molds. The only thing I did have trouble with was the measuring part. Didn't understand the measurements that came with it. So it was a lot of trial and error. Also when we closed containers the B container got stuck like crazy glue stuck. So it's very fun craft to do with ur kids. Just needs better instructions on how to use. I will definitely buy again

I bought this kit to make blank squishies for a library program. Everything worked fairly well once I got the hang of what I was doing so I thought I'd list a few valuable tips.1) ROOM TEMPERATURE AND HUMIDITY MATTER!!! One of the molds I made was a doughnut shape and anytime the room was too cool or too muggy the foam would fall like a deflated cake.2) Try to use it up all at once. This will definitely take some time (my kit yielded approximately 70 squishies between my doughnut and owl molds), but once Part A of the set is open you will not be able to get the cap back off if you reseal it overnight (I had to break the lid off when I reopened Part A).3) This is NOT an eco-friendly craft. It required a ton of little plastic cups and wooden craft sticks for mixing, not to mention the paper towels from cleanup.Overall if you need to make a ton of something for kids to decorate and you have the patience to mix multiple batches then it is worth it, but I will personally not take on a similar project with this material.

This is not for the faint of heart. It is toxic and very very unforgiving. Please watch YouTube videos and read their site for help.It’s insanely sticky, so use silicon forms where you’re pouring.Measure!!! Use a scale, it makes it so much easier. 1A:2B or .575 difference. 10 grams A = 17.3g B. This is insanely important. Very unforgiving. Yellow bottle is the hardener…. Too much yellow it’s too hard or doesn’t expand. Too much blue bottle it doesn’t stay expanded and looks weird.Mix until 35 seconds and your shoulder is on fire. When you combine the chemicals after measuring exactly, mix immediately and use a timer. Mix until your shoulder burns. Really really really mix. Minimum 35 seconds, then pour.Lastly, it doesn’t like cold. Has to be 72+ or it doesn’t fully expand. This is all listed on the website and 100% accurate.Measure - mix - warm - remove after 25 min.It’s a great product and has a lot of uses if you can do the above.

What I liked is this product did exactly what I was hoping it would do. What I didn't like was that you have to work very fast because of how fast it sets up. It just means you have to be very organized before you mix the product. I used this product on a vintage car steering wheel horn pad that the original foam had split and separated from the horn pads structure.

Buying squishies and repainting them or buying unpainted ones and painting them yourself is cool, but making your own is even better. I use silicone baking molds, candy molds and ice molds to cast mine and have had great results. This starter package will make a LOT of squishies. It is easy and the company's web site has great videos explaining everything. BE SURE to pick up lots of paint stirring sticks at some place that sells house paint because you will need them. This is great stuff an easy to use. Just know that once you mix the two parts (A & B) together you have have 30 seconds of so to get it in the molds. This is very different from acrylic casting which has a much longer pot life.

Ive used small amounts thoughout the year and have noticed that one part has thickened considerably. Its been a year and now when measured and mixed properly it will not cure. Was stored in a refrigerator at 40°f and allowed to come to room temp before measuring/mixing each use.Also was softer foam upon curing than i was looking for. This is in the Shore A or B range. I wanted something in Shore D.
