How to Apply Photo Emulsion to a Screen

Applying emulsion to a screen is quite easy but it can be a little messy. I am going to try and explain as best as I can in this post.

First off you need a clean screen, a coating trough and of course photo emulsion.

Coating trough

Second you need to put a generous amount of emulsion into the trough, don't put too much into the trough as when you start to apply it, it will end up flooding over the edges of the trough and it will go everywhere (and it not easy to get off things). I always put a little but more than what I think I will need and then out the excess back into the tub.

Once you have enough emulsion in the trough it's time to apply it to the screen. 

Line the edge of the trough up to one of the bottom corners of your screen, place the trough up right so that the emulsion flows onto the screen (don't let it overflow on the edges!!) once the emulsion is on the screen tilt the trough back, normally to about 45 degree angle and pull the trough up the screen.

You should then be left with a line of emulsion on the screen, if it ends up being a bit patchy then you can go back over it some more emulsion.

Note: you only need to coat the one side of the screen not both.

Once you have coated the screen you need to make sure that it is stored somewhere dark (pitch black) and dry, the emulsion takes about 3 - 5 hours to dry (depending on the temperature of where you store it) unless you have access to a dryer then the emulsion will be dry within about 20 -30 minutes.
