Start Here: Sandcarving Wood

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 photoresist and the sandcarving process.

Make sure you have a photoresist film with a layer of adhesive. Even if you are using a self-stick photoresist film, an additional layer of adhesive should be applied for the photomask to adhere to the wood surface. A 5Mil or 6Mil photoresist film works great on wood surfaces, which allows the blaster to increase the blasting pressure. A higher pressure will speed up the blast time and obtain depth faster. 

Sandcarving wood relieves the wood grain but provides no contrast. A clear coat or a color paint-fill application is recommended for the etched area. I recommend using aluminum oxide in place of silicon carbide for wood surfaces; silicon carbide is reflective and will shine through paint if it is not cleaned properly.
