Wet Work - Washing, Deacidification & Bleaching

Duke

What ratio of water to calcium hypochlorite worked best? In other words what is the formula for spray on method?

Eisenhower

2 grams per liter i think is what the literature indicates, but i'd check first. 

Duke

First linen backing attempt. The Breyer left some dark lines will have to invest in a better one.

Eisenhower

NO! No more brayer! I use one for smoothing out the masa, but not anymore when the poster gets laid down. Too much pressure on the poster/fold lines. 

Duke

Ok what do you use to smooth out poster? The dark lines did disappear.

Do you bleach posters from the 80s?
And if they don’t need it, are you just doing the de-acidificationbath, then rinsing, and then backing?

Charlie

You don't bleach anything if they don't need it.

Duke

Agreed, bleach can be very tricky, and some colors di nit like bleach at all.
