    Frequently Asked Questions:

    Frequently Asked Questions for Exposure & Wash Out Kits
    What is an exposure and wash out kit used for?

    An exposure and wash out kit develops photoresist film for sandblasting. The exposure unit hardens your design under UV light through a film positive, then the washout sprayer rinses away the unexposed film, leaving a finished stencil ready to etch glass or crystal.

    What is a Letralite exposure unit?

    A Letralite is a compact UV exposure unit that develops photoresist film quickly, often in around 20 seconds. It wraps the film and positive around a UV bulb for even exposure, making it a popular choice for sandcarving shops and hobbyists developing their own stencils.

    Why do I need a pressurized washout sprayer instead of a regular sprayer?

    Washing out photoresist film requires a steady, pressurized fan spray to clear the unexposed areas cleanly. A standard kitchen or garden sprayer usually lacks the pressure, which can leave residue or damage fine detail. A dedicated washout unit gives consistent, repeatable results.

    What do I need to expose and develop photoresist film?

    You need a UV exposure unit such as a Letralite, a printed film positive of your design, and a pressurized washout sprayer or station. Together these develop the film into a sandblasting stencil. An exposure and wash out kit bundles these essentials so you can start sandcarving.

    Is the same exposure and washout setup used for all photoresist films?

    Most Rayzist self-stick photoresist films, including SR3000, develop with a UV light source and a pressurized washout, so one exposure and wash out kit works across the range. Always follow the exposure time recommended for your specific film and light source for best results.
