Using Plasters in Mural work

Lately I have been getting calls for an olde world look to my mural painting. I enjoy utilizing plasters in my mural work and there are several ways I go about this. Traditionally if I am using a lime based plaster I will paint my mural as a fresco using egg tempera, earth pigments and water. This method is time consuming, and more expensive ar far as products being used, but the results are quite stunning, and finished murals look like old Italian walls. I also use a method where I paint my mural using regular artist acrylic paints. I use very saturated colors, and then I apply carefully placed layers of synthetic plasters on top of the painting. This method produces a crusty old worn down look that is quite attractive. The plasters can then be sanded for even more age, waxed or left alone.
