I've made prints of 3 8x10 negs side by side in panorama format, and also 4 8x10 negs, stacked 2x2 so that's 8x30, 10x24 or 16x20, depending on orientation. The coating is fairly easy with the 4" Richeson brush. I once saw a video on YouTube with a Spanish photographer that had her solution in a trough and rather than measuring enough for one print, she just had a saturated brush and liberally went back and forthe between the paper (very large) and this trough. What an extravagance! Anyway, for me, I multiply my drop count for a single 8x10 to however many negs are involved, mix it well, pour it out and move swiftly to get the puddle shoved around evenly. Then I remember that slow, light and smooth results in the best coating. The coating has been the easiest part of it, for me.|
For me, the pain in the neck when printing this large is tray size. My sink only really accomodates ONE 20x24 tray, so I use a single tray method in which my PotOx and clearing baths are stored in wide, flat Rubbermaid containers. I develop, and pour that back into the Rubbermaid, and repeat with the others, separated by rinse steps. It's a slow, tedious process, but I enjoy it in a way. And, this tray is ALSO my wash tray, so I'm lucky to get one good print in a printing session.

Although I'm a neophyte in pt/pd and have only made small 4x5 prints thus far, my reading has led me to believe that you should use a flat wash brush of about 4".

How does one go about coating prints in the 20x24 range in pt/pd? Any special tools or procedures?
