Plaster Mason

I am working on a piece of art, and I want it to have texture and dimension. I spread a layer of plaster of paris on the board, and after it was completely dry, I picked up the board, and the plaster cracked and crumbled off the board, just slid off in chunks. Is there any way to make the plaster stick to the board, and not crack when the board is bent slightly? I have thought adding a frame to the board would help with the plaster not sliding off. Or perhaps someone may know of a better medium to use for giving my piece texture and dimension. After speaking to others on the web, I found the answer. Instead of plaster of paris, try cheese cloth and papier mache mixture – To make it, combine 1/2 cup all-purpose flour and 2 cups cold water in a bowl. Add this mixture to a saucepan of 2 cups boiling water and bring it to a boil again. Remove from the heat and stir in 3 tablespoons of sugar. Let it cool; it will thicken as it cools. Once it does, it's ready to use. (tons of other recipes on the net) Soak your cheese cloth through the mixture, place it on the board in the shapes you want, you can build up on it and it dries quite quickly. It is very durable and easy to paint. I also sometimes use toilet paper or paper towel – but paper will contract slightly when it dries; sometimes creating gaps that are difficult to fill in with paint. Also acrylic Molding paste is really cool, quite flexible, durable, you can also cut into it and sculpt it when its dry, you can mix it with your paint and have it colored before or paint it afterwards.

    NO the plaster is always going to crack because it is not flexible try roofing patch it will stick and bend and can be painted on the only drawback is it takes a while to cure and will melt or lose shape if it gets too hot Death To Infidels .... LA LA LA LA LA LA LA LA LA LA
