If you are using a 5mil photoresist film, then we recommend a blasting pres- sure of 40 to 45 psi. A blasting pressure of 45 to 60 psi can be used for 6mil or even a 9mil photoresist film. METAL MAGIC Metal surfaces such as tumblers, flasks, knives, pewter, stainless steel, and brass can etch in seconds. Sandcarving has become a popular method for metal surfaces because it is a quick process and provides the option to paint-fill. Sandcarving will only remove the surface; depth cannot be achieved in metal. We recommend using a self-stick film for metal surfaces in 3mil or 4mil with a quick etch. Self-stick film removes easily after sandcarving—this benefit provides a perfect painting stencil. For coated metal surfaces (Yeti and Ozark), use a 5mil pho- toresist film, which will provide enough sand resistance to remove the coating. It is essential to paint in light coats for metal surfaces since there is no depth. THE BEAUTY OF WOOD 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 5mil or 6mil with added adhesive is recommended for all wood surfaces. The adhesive provides the extra tack required for the photomask to adhere to the material. Another important note when sand- carving 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 recom- mended blasting pressure with 5mil is 40 to 45psi or 6mil at 45 to 60 psi. Sandcarving is quick and easy. Use pho- toresist film to achieve detail and depth into the surface. Get creative with artwork or use multiple colors of paint to produce a unique product. Liz Haas has been a teacher, trainer and show coordinator for Rayzist Photomask for the past 15 years. For the past 10 years, she has actively taught workshops on the pho- toresist and the sand- carving process. A&E
