Get creative with sandcarving wood by adding multiple colors to the etched area. Sandcarving attains depth into wood and also reveals the beautiful natural wood grain. Photoresist film allows incredible detail into wood surfaces; leave the stencil on the surface after sandcarving and add one or multiple colors. The wood grain absorbs the paint and provides contrast to the image. You will find different wood materials will sandcarve faster than others. A 5 mil or 6 mil with added adhesive is recommended for all wood surfaces. The adhesive provides the extra tack required for the photomask.
Another important note when sandcarving wood surfaces is to use aluminum oxide abrasive in place of silicon carbide. The silicon carbide is a reflective product and if any grit is left in the wood grain, it can reflect through the paint. The recommended blasting pressure with 5 mil is 40 to 45 psi, or 6 mil at 45 to 60 psi.
