Make sure your emulsion has the diazo sensitizer added. If you are mixing a new jar of emulsion, please date the cap to indicate emulsion has been added.

Fill your scoop coater with emulsion. It's better to use more than run out while coating a screen.

Do two passes on each side: one with the scoop coater nearly perpendicular to the screen to fully coat the screen, and one with the scoop coater nearly parallel to scrape off all the excess emulsion.

Leave the screen in the darkroom overnight to let the emulsion dry.
