@Jolodo posted:I am working a a large water scene with docks and I made the land scape out of plaster paper covered insulation foam. I painted it and every time I touch it the plaster crumbles I know I have to rip it up and start over but is their a better material to use? Also what did I do wrong to have the plaster be so brittle? Thanks in advance you guys ae always the best.
Something very wrong with the plaster.
Too many over think this stuff. Keeping it simple succeeds. Start with a fresh bag of Hydrocal. Or you can waste time and more money using other stuff that makes work.
You can apply Hydrocal directly over foam insulation; mix up a bit at a time in a plastic bowl and literally just paint it over the terrain with an old brush that you will throw away later. You don't need a thick layer either. Could also apply Hydrocal directly over a woven terrain of cardboard or even just brown paper bags - something somewhat heavier in weight that just newsprint. When done, clean the brush. Pop the plastic bowl clear. Repeat as needed to do more scenery.
