A&E JUNE 2019 • a-e-mag.com 65 Sandcarving layer; this can take from 24 to 72 hours. I recommend not turning over a painted project until the piece is fully cured. After the tile was sufficiently dry, I taped off the areas that would get the second color or no color at all: the zigzag line, the upper left field, and text as well as the outside border. I reapplied a new resist to the zigzag line to protect it from the white paint. I began to spray paint the exposed areas with the white paint. Be sure to shake the can for a while, wear a mask, and, if pos- sible, spray outside or in a well-ventilated area. At this point, a bit of patience is required: the paint needs to be sprayed on in thin layers and from different angles since there are sidewalls in the blasted areas on projects like this; these won't get covered if you only spray from one side. I sprayed one thin coat. You can watch the stone absorb some of the paint. After a little while, I sprayed a second and third coat, each from a dif- ferent direction. I needed to let the paint dry enough so that when I taped these areas off, the tape wouldn't stick to the painted areas. This takes a little patience. I like to try the paint on the resist to see if it is dry enough to proceed. Never touch a field that needs to stay pristine; once you touch still-sticky paint with your finger, you will leave a print in the surface and have to add another paint layer to try to get rid of it. When the white was dry enough, I taped off those areas with a low-tack tape. I had to concentrate on the zigzag line, which is right to the white rectangle. We did cut an extra stencil from stiffer white vinyl (I used the zigzag before painting the white) and used the rectangle to cover it up in prepara- tion of painting the zigzag turquoise. I also removed the tape from the upper left field, which would receive the same color. I proceeded as before, applying thin coats from different directions. I knew there would be some bleeding of the paint into the white area since I couldn't stick the stencil down so well that it would damage the paint layer of the rectangle; some touch up was required. I did that by spraying some white paint onto an acrylic sheet and used a paintbrush to touch up the overspray areas. I let this paint layer dry well. When that was accomplished, I removed all the tape and began removing the remaining stencil from some areas and the text. This needs to happen before the paint cures, oth- erwise the paint will form a bond with the stencil and rip during removal, breaking up the paint edges and making them look frayed. After all was done, I placed the tile into the frame, taped around the edges, then placed a piece of cardboard over the tile and stapled it to the frame. Again, I taped off the edges; the project was complete. © Ruth L Dobbins 2019 A&E
