Hi! A few weeks ago I started this thread and got some fantastic advice: http://www.diychatroom.com/f4/stripping-wallpaper-what-photo-how-fix-168506/

I decided to do one section of the downstairs of the home at a time starting with the hallway. I tore down the paper, washed the walls, sealed with GARDZ, patched with joint compound, resealed with GARDZ, primed, and painted two coats. The hallway looks great - smooth, no bubbling or other issues.

I started to work on the large wall in the family room tonight and it's a disaster. :( They wallpapered OVER wallpaper and in some parts the first layer of wallpaper was put directly onto the plaster or directly onto some sort of putty they used for patching. The plaster is crumbling away in chunks. Will the steps I followed to do the hallway work? I would seal the wall and work on patching everything up with joint compound, but I am wondering:

Do the walls need to be re-plastered or patched with plaster instead? If yes, what specific product do I look for? I read that a product called EasySand could be used for this. Would that do the trick?

Here is an image of the current mess: http://imgur.com/1Eem6rP

Thank you for the advice.

Yes easy sand will work for your first skim coat. If you have not worked with it before here is some tips;
get the longest trying one you can find at least 90 minute
mix in small batches
put on as smooth as you can
when it starts to get stiff in your pan throw it out CLEAN out your pan and all tools and make another batch. The reason for this is if you add more water thinking you can use it longer it will weaken it. It dries by a chemical process and once it starts it can't be stopped. You MUST clean all tools because if the process has started with the mud on your tools that will start the process in your new batch.
mix with hot water speeds the process, cold water will slow it down.
Hope this makes sense to you. Good Luck

Yes, that all makes sense, thank you for the tips! Looking at the links to the product last night I figured I would want the longer drying one so I had time to spare.

Should I put GARDZ on the wall first?
You said the EasySand can be used as the "first skim coat". What other coats or steps would I need to follow to get the job done? I was under the assumption I could use the EasySand to fill in the holes in the plaster.

To put the Gardz on the wall first will not hurt anything and will seal the wall. Use the easy sand to fill holes but then use regular mud to put on a thin skim coat and feather out away from the repair that will help to hide the repair. Usually the first coat is pretty rough so sand down any ridges between coats. Also what size knife are you planning to use?

Thanks!

I am hoping the rest of the walls aren't as bad but I'm not counting on it...lol Now that I have a system down it will hopefully go faster.

Speaking of frosting a cake, I am using my old handheld mixer to whip/mix the mud. :wink:
