Liquid Emulsion Questions
I have coated wood with thick layers of a diazo emulsion in the
past....... What I did was to apply numerous coats of a sandable sanding
sealer to the wood sealing it totally....... I only needed it done on the
front but from what I can see in your case, you would have to do the entire
piece......... I imagine lacquer or shellac would work as well.... The soak
time frame may be limited though depending what you use........... If you do
not do this you will get sever warpage beginning almost immediately even if
you just coat the surface......
Is it possible that you just coat only the front surface using a
brush on method and then create a dam around the peice to devlelope , fix
and rinse.....
Also You could build a recirculating flood system by just drilling
small holes over a length of PVC, caping it at one end and then run a tube
to a small pump and well in some sort of tray set up.......This would
minimize your chemicals and you could just tape of the back using visquine
or cut a piece of plastic plexi and tape that in place......
