Title: wallpaper removal - looking for a sanity check
Post by: mrFinpgh on July 01, 2018, 01:30 AM
I spent the afternoon removing 3 layers of painted wallpaper from my old kitchen.  Surprisingly, all the layers came off without too much persuasion.  I had mentally resigned myself to spending the weekend stripping the walls, so this was a nice surprise.  Part of a drain vent pipe also came off   [eek]

Then I sprayed the walls and a couple stubborn spots with Safe and Simple wallpaper remover liquid and scrubbed the residual adhesive off the wall with an abrasive pad.

There's a lot of areas where that scrubbing the adhesive took up what seems like a poorly applied latex paint that was on top of the plaster.  In some areas, I could pull up sheets of this paint about a foot long.  I am assuming this isn't glue, but I want to just double check my assumption.  Are there wallpaper adhesives that look like latex paint?  I'm used to seeing wallpaper adhesive as a clearish goo that I need to scrub to remove.

Thanks,
Adam

Sounds as though might be PVA 'glue.' 
Rather than apply a traditional 'mist' coating first - if needed, some people would, incorrectly, apply a PVA coating before decorating. 
And yes, depending on your luck, can be a royal pain to remove.

Forgot to say: to save time, there are products that you can apply over PVA coatings, that will 'prep' the surface for decorating - check out Zinseer products for example. 
Which raises the question of how you intend to decorate; needless to say, thorough preparation is important - might need to research separately.

My guess is that someone painted over unremoved wall covering sizing.  That makes it really a pain to get a wall smooth and looking right.  I'm dealing with that right now in a bathroom in my own house.  I may take the RO 125 to the wall to try to level it out enough to paint and look right.

I thought PVAs were generally clear or at least translucent?  Here's a couple photos of the walls in question:

[attach=2]
[attach=3]

My plan is to patch all the holes in the wall, replace some plaster that had failed, and then skim everything to get back to a smooth surface. After that, I'll prime and paint.  I just want to make sure that in skimming the wall, the remaining 'latex' isn't a failure waiting to happen!

Maybe that's it.  Given that I'm going to skim everything, my main concern is adhesion - I'll level everything out but definitely want the plaster to stay on the walls.
