Glue/Sizing/Primer? I don't know what it is!
I am taking wallpaper down in my foyer/halls, etc., using Dif for the process. I had no problem getting the "top" layer off and not too much with the liner either. Unlike other rooms I've done, there was no visible glue to be scraped off -- just a sticky, slimy residue after the liner was removed.
After wiping with warm water and then warm water and Dawn, the wall (just a test area) is still "tacky" feeling. Should this be a concern or might it just be "primer" that will be OK under the latex paint we plan to use?
Wall history: These were painted with a latex paint (as far as I know) by the PO, then I had them professionally wallpapered. I'm pretty sure the hanger used a sizing/primer on the walls, but I don't remember for sure.
I have read a lot of the posts on here regarding wallpaper removal, but I don't find anything that seems to be the same problem as mine. I would appreciate any thoughts/recommendations!
