Hi,
I posted this question at the tail end of this thread: http://www.controlbooth.com/forums/...63-carving-mortar-lines-polystyrene-foam.html
but haven't gotten any responses.
I did a search and found the recipe for Van's scenic stuff, but I don't think I need to do that for this application. I just want to solidify the base color on a polystyrene wall (white styrofoam) and am planning to add joint compound to the gray paint that I have purchased. I don't need texture, I've got that with the foam. I just want to seal the foam and minimize the number of coats it will take to seal and solidify.
My question is how much joint compound per gallon of latex paint? I've got 32' x 8' feet of very exposed wall and I plan to use it for many years in the future if possible and I'm trying to minimize the weight for storage and moveability.
Experimenting to "see what works" won't help because the color will change with the amount of joint compound. Thanks in advance CB.
Phil
