drug references aside..
does the little bottle have a liquid or a small amt of powder in it? normally an emulsion that uses a diazo powder comes w/ a the brown bottle of diazo powder that you fill w/ water to the shoulder of the bottle and then mix it well into the emulsion. If yours already has water, then just mix that in as is.
Let it sit for a couple hours in the dark w/ the lid just set on top of the bucket loosely. You're good to go after that. If you need the screens right away it's not going to make a huge difference to coat them as soon as you mix it. Just coat slow to avoid bubbles.
