I’m working on a layout and I am using Hydrocal to build tunnels and rocks and scenery. I’ve used some Sculptamold & hydrocal on a test portion, and used a wa***o stain. The two stain differently. Would plaster of paris do the same. Is plaster of paris really lighter than hydrocal?

Welcome to the forum. All three plasters take stains differently and it is easiest to separate plasters by natural boundries like fault lines or geologocal layers. If they need to be blended I have good luck with artist’s acrylics and lots of patience. I also use a lot of liteweight drywall seam cement. It takes two days to dry and that gives chance for carving and forming.

It’s the other way around. Hydrocal is lighter and stronger.
Here is some info on plaster from PlasterMaster.com
I bought a 100 pound bag for $35. You won’t find it at Home Depot. Look in your local Yellow Pages for plaster, building supplies or cement. It took quite a few phone call to find it.
If your plaster (any kind) has set and dried for a few days, before painting or staining you should wet it to the point where it doesn’t absorb water. It will help take stain and water based paints evenly.

Opps. Yes I really should have written Hydrocal lighter than Plaster of P. I’ll just keep using the Hydrocal and check about the supply.
Thanks for the replies guys.
