As I tell everyone I teach, your prep work greatly affects your final quality. Work on a clean surface when dealing with your resist. If you have dust on your design and expose it in the Letralite, you will get pin holes in your resist that will ruin your item when blasting. Step 1: Before placing your design, clean the glass with dena- tured alcohol to remove any grease or debris. Take your time placing your design — remove as many air bubbles as possible with your squeegee. Once your design is placed, use your wire wheel brush to pop the membrane on the resist. After popping the membrane, make sure to press the resist onto the glass and force out any remaining trapped air. Step 2: Now that the design has been placed, it is time to mask off the glass. Start by surrounding your design with masking tape; press it down onto the resist to create a seal. en work your way out from the resist and cover the exposed glass with overlapping layers of tape. I like to hold the piece to the light to see if there are any missed areas that still have exposed glass showing. Step 3: Once the item has been masked off, it is time to go to the blast cabinet. Before placing the piece in your blast cabinet, make sure that no resist has lifted off and press it down one last time. When starting to blast, your sand and air flow need to reg- ulate to a steady stream. I try to keep my dust contained, but that's easier said than done. I highly recommend you have a separate blast room. If you have dust on your design and expose it in the Letralite, you will get pin holes in your resist that will ruin your item when blasting.
