How can I remove dried white glue from a plaster wall? It held wainscoting on - which I have removed. I have tried chisel and am gouging the wall.
The best and easiest way of repairing is to apply ¼” Sheetrock over entire wall and finish. You will have to visit your local drywall contractor supply house to purchase ¼” thickness. The other alternative would be to remove the drywall for just the damaged area and then replace it, tape and fill.
