stone and brick finishes for the exterior of Merriman Park. On the far left is a stucco finish. The middle is the accent color and on the right is my first attempt at stone. I have to say, the "real" samples look a lot better than this photo! Oh, well...
I also tried to do bricks, but something went terribly wrong and I am re-doing! Not sure what happened --I think I ruined my batch of gesso-- either too much glue or not enough. Or maybe the coats didn't dry long enough? Not sure.
The stone and bricks are done the same way: a layer of gesso, then layers of paint on top to mimic the stone or brick color. Once that dries you scribe the mortar lines with a straight edge: larger squares for stone, smaller for brick. Then you go back with paint and touch up the individual stones.
I've tried using different tools to scribe the mortar joints, but haven't discovered the definitive one, yet. The tong of a dinner fork seemed to work best, but there must be something better than that! Looks like there will be more experimenting with tools and colors until I figure out what works and looks best.
