Hi, I’am thinking of using some sculptamold for scenery and there are no instructions on mixing. What is the ration of sculptamold to water?
Don
The instructions are printed on the side of the carton.
Doesn’t everyone put them there? gees now wonder why I never get that stuff mixed right.
Maybe your last box came from Russia and the instructions were written in Cyrillic?[:)]
Woodland Scenics Mold-A-Scene plaster:1 cup of mix to 3 oz water.
The basic ratio is the same as plaster of paris. One part water to two parts sculptamold. You can vary this somewhat but don’t make it too soupy.

Sorry the sculptamold came in a clear plastic bag with blue lettering and no instructions on mixing.
RioGrande:
I’ve been using Sculptamold for scenery for about four years, I really like it. The instructions are on the bag, but you have to really look for them.
For general use, about two parts Sculptamold to one part water will work extremely well. The Sculptamold is between Plaster of Paris and Hydrocal as far as weight, but because of the ‘paper maiche’ consist, allows more working time for forming while it dries. It dries to a ‘grainy’ finish, which is excellent for ground cover and a lot of rock-work. It takes carving very well.
If you want to use it with rock molds from either Woodland Scenery or Bragdon, my suggestion is to mix it 50-50 with water, to obtain a ‘soupy’ mixture. Now, this takes quite a bit more time than using either plaster or Hydrocal for casting rocks, but here’s what I do, and it turns out to be worth the time.
Pour the soupy mixture into the rock mold, let it set for about 15 minutes, until it begins to get the consistency of oatmeal. Then press the rock casting to whatever scenery you’ve decided on covering, hold it to the scenery for about 7-8 minutes (yah, this takes patience!) then slowly release the rock casting. The plaster in the Sculptamold will have settled into the casting for the detail, and will give you a good, detailed and slightly grainy ‘rock’ finish. You don’t really have to do any carving, except for smoothing out the edges. And the Sculptamold will take stains VERY well for at least two to three hours before it ‘sets.’
After it’s ‘set’, I find that it’s ‘tougher’ but not nearly as brittle as either Hydrocal or plaster.
I like the stuff a LOT!
Here’s a photo of some rockwork I have on my Yuba River Sub using a ‘collage’ method combination of Sculptamold, Bragdon&n
Thanks for the info and the layout is great. Maybe someday mine will be just as nice.

Don,
I’m a big fan of Sculptamold. I don’t measure, I just mix it to the approximate consistency of thick oatmeal or cottage cheese. Using warm water seems to make it mix up better than cold.
I’ve never used it for casting, although I know people who do, but you can make really good rock faces with it by slapping it on a hillside and pressing lines into it with the side of a palette knife. As someone else pointed out above, you can mix and match this with rock castings. This method gives me a good approximation of cutaway hillsides in New England, where a harder peice of rock will endure while the softer rock around it weathers away (think Niagara Falls).
Ditto.
