Rigid Foam Casting Tips 

How did you made hard pink sides of mold? I think did you used white cement coats? And stain is wooden ?? Plz reply

wow great job

fill you mold with water, measure and write with permanent marker the volume of mold.

One GLARING error.... 6lb foam is always going to be 6lb foam, it doesn't reduce weight & become 4lb or 5lb foam. I think what you meant to say is through restriction in the mold, it may fill the same volume (not density) as 5lb or 4lb foam.

Thanks for the information, I have cast a lot in PU but not yet in foam, so this is very useful. One general tip that might be of interest: weigh an empty cup and then a cup with the leftover after mixing and pouring, to get an impression of how much is left over. This is a way to get better in mixing the right amount, as sometimes you lose more than you'd expect, but overcompensation is just a waste of material. :)

How effective would this be at lost foam casting?

How much lifespan does a rigid polyfoam structure have you think? I purchased a display piece that is 30 years old and I’m worried about its longevity, even though it seems fine now

I'm getting hard brown plasticy areas in my cast. Any help?

Thanks for sharing. The compression method ensures minimal waste too ❤

Could these components be painted? Or may we use any kind of pigment to add in casting process

Can you cast in a latex mold? What would you use for a release? If you cast in a plastic mold, would you need release?

Very nice

excellent tutorial thank you!

Really nice video thank you.

What is the lifespan of the silicone mold for rigid casting foam?

What product was this mother mold made of? Thanks

Are any of your forms closed cell for watercraft?

Could these PU foam heads be turned into metal with green sand casting?

will this work on 4 foot statue?

Couldn't you just pour water in the mould before hand? and measure? to get your foam requirement?
