So...this acrylic compound dries hard..?? I often find myself rushing to get the plaster in place before it starts to harden, and then have little chance of sculpting it. Sounds as if this stuff would be good to lay over the plaster and fiddle with it to get the effect I want. Thx. for the heads up...:thumb:
That is correct, it dries hard, and can be carved. With the problem you described with plaster, the best solution is a type of hydrocal called dental stone, that I used to get from U S Gypsum. It may be possible to get it through a dental supply outfit.
It is forgiving about the water mix, and will dry hard no mater what; you can make it soupy, and it still dries hard the coolest thing about it is most plaster, once it is set, if you get it wet again, it will soften and never return to it;s full hardness. The dental stone, however will return to full harness; so if it sets up on you, you can dose it with a spray bottle to soften it up enough to work (the stuff is hard!), and when it dries out, it returns to full hardness.
another real advantage is when you work it when it is damp, it thinks it is rock, and if you break off a chip, it breaks off looking like rock, a real advantage.
a disadvantage of the dental stone is it weighs a ton! not for portables!
I just got done using the acrylic modeling compound it fill in some of the cracks in the foam and between the foam and the plaster. while I was at it I used it to add some texture to some of the plainer foam rock strata. very useful stuff
