- Brushed or rolled on layers of white glue or Mod Podge (it's just white glue) will be the cheap option…
- If you want a more 'rock' like surface, a 50/50 (give or take) blend of a latex primer and plaster joint compound rolled on will get a real hard coating…
Van's Super Scenic Dope Recipie?
?? ??
??"So Van, I went to tell a friend about your VSSD and when I did the search I found 3 different recipes. I assume that means you don't really have a recipe and sort of fake it. I thought I would post this on the boards instead of in a P.M. because your VSSD sounds like a cool product we all should mess with a little. Could you choose one for us to follow as a starting point and maybe comment on what happens if you alter the ratios. Thanks!" (answer, #3 for rocks, 1 or 2 for a thiner coat)?? ?? Below are the recipes you have posted in the past.?? ?? Recipe #1?? ?? "3 qts flat latex paint < any color, good place to use up all the left over paints from the scenic painters shop>?? ?? 3 – 5 tubes acrylic latex painters caulk ( often called Alex caulk)???? ?? 1 cup Joint compound?? ?? Recipe #2?? ?? 1 gallon latex paint?? ?? 2 tubes Latex painters caulk. < not silicon>?? ?? 1 cup Joint compound?? ?? 1/2 cup water putty?? ?? Recipe #3?? ?? "about 1 quart of latex paint ( this can be pretinted, neutral base, or a "waste" paint, as long as it's latex.?? ?? About 4 tubes of Latex caulk. Do not use Silicone caulk. Some Latex caulk are called 'siliconized' and those are ok to use as they are still latex based.?? ?? About 2 cups of drywall mud. Adds thickness and aids in setup time and helps leave a harder finish when dope is cured."
From the Manufacturers
The makers of Styrofoam??? ??http://www.styrofoamcrafts.com/tips/
- Paint with an acrylic craft paint. Solvent-based paints may damage the foam (see paint manufacturer's instructions for details). Use a brush with stiff bristles for the best coverage. Place small shapes in a zip-top plastic bag, add paint, seal the bag, and rotate shape until it's completely covered. Remove from bag with pick and let dry."
- Use spray paint with caution; read the label carefully to determine whether or not it???s safe for STYROFOAM Brand Foam.
- Hint: Insert a floral pick or wood skewer into your foam shape to use as a handle while painting. When done, insert the handle into a block of STYROFOAM Brand Foam while paint"
- Cover foam shapes with plaster, wallboard compound, gesso, modeling paste or other coating materials??
- Smooth it or stucco it, swirl it or sculpt it
