What is the best way to clean rock molds after use?
An old toothbrush, warm soapy water and a bit of light scrubbing will take dried hydrocal right off.

Rock Molds are made of a non-latex polymer.

Can I use Shaper Sheet Plaster in your rock molds?
Yes. Shaper Sheet Plaster provides excellent detail when used as a casting plaster.

What is the dry quantity of lightweight hydrocal needed to cast one rock in a rock mold?
Rock castings can be made from the following Woodland Scenics plaster products: Lightweight Hydrocal Plaster (C1201), Super Strength Plaster (C1199), Shaper Sheet Plaster (C1180), and Carving Plaster (C1198).

Fill the Rock Mold with water, and then pour the water into a measuring cup. Measure the amount of water and divide by two. This is the amount of water you will add to the Plaster. Times the water amount by 2.5 to find the amount of Plaster you will need.

Example: Rock Mold holds 4 fluid ounces of water.
4 fluid ounces divided by 2 = 2 fluid ounces.
2 fluid ounces times 2.5 = 5 fluid ounces.
Add 5 fluid ounces of Plaster to 2 fluid ounces of water. Prepare Plaster per instructions on carton.

There is too much black wash on my rocks, can I lighten or remove the black wash and rock coloring?
Yes, the black wash can be lightened, as long as it has not been sealed already with Scenic Cement. Flood-spray the casting with hot salt water (1 tsp in 6 fluid oz of hot water). Wait one minute, and spray again if needed. Dab with paper towels to remove the liquid. The base colors will remain on the rock, but the coloring will be much lighter.

If you would like to start over completely, paint the casting with White Earth Colors Liquid Pigment. Dilute the White Pigment 1:1 with water.

When satisfied with the coloring on your casting, spray with Scenic Cement to seal the colors and let dry.
