Moderator TaleSpinner Posted November 12, 2009 Author Moderator Share Posted November 12, 2009 Again, no slight against the OP. The technique here looks pretty cool and is well executed. Just wondering if the same short lifespan is a factor/fear here? Any word on how this stuff handles once painted, etc? No slight taken at all. So far it holds up great. I made the first pieces over a year ago. My boys even used one piece in their sand box for 6 months. I dusted it off last month and spray painted it and it looks the same as it did the day I made it. I take it the foam does not adhere during curing to the wax paper? If that's the case, you can line the sand mold with wax paper to get smoother sides...potentially a way of making square or round building-like terrain. As another tack, have you tried sanding or otherwise removing the adhered sand? The foam does not stick too tightly to waxed paper. I haven't tried any other mold than coarse sand (it's what I have and wanted so far). I would assume that any mold you make could be coated in parafin as a release agent. If you wanted to try this with a building, I'd have each wall be a separate section so you could peel it away from the foam, as the foam does stick slightly to the wax.

Kataclysm Posted December 12, 2009 Share Posted December 12, 2009 While I have not made any terrain with this stuff, it is very durable. As in nigh on indestructible. I used to live in an old farm house with stacked field stone as part of the foundation, in a winterizing effort I spent 6 hours crawling under the house and used about 10 cans filling in the gaps from the inside. I simply carved off the excess that expanded tot he outside, painted over it and its still solid today. That was close to 8 years ago and I live in Kentucky, which gets just about every type of weather in the world. So I would imagine that if compressed properly, (adding the weights on top of the board) these would last a very long time. That's probably why the ones from that company fell apart, they just sprayed the stuff in the mold and didn't compress it. But, I am for sure going to give this a go, looks super easy and very fun.

Mr.Wizard Posted December 13, 2009 Share Posted December 13, 2009 I'm getting the stuff together for a moon-mining diorama, and this would great for representing the tough lunar regolith. Quote Link to comment Share on other sites More sharing options...
