How to remove painted-over wallpaper paste?

bagelkDecember 28, 2011

Hi, I am new here. We just removed wallpaper in the kitchen, cleaned the glue and found a very uneven painted surface. It is clearly a thick layer of dried wallpaper paste painted over or primed over. Surprisingly, it holds really well, no pealing. It does come off when sprayed with wallpaper removal stuff, but this is very tedious and slow. I've tried to use latex paint removal paste, but that was a mistake - no progress, but a big sticky mess. I know how to patch a drywall, but have never tried to skimcoat the whole wall before.

Sand it off

Thanks, christophern. We've tried sanding, but it doesn't come off easily, and we'll have to sand 3+ walls. It is not like a few spots, but we have whole walls heavily "textured" with painted glue. It seems that nobody even tried to wash off the glue before painting over it. How about covering it with Gardz, and skimcoating? The drywall mud is a lot easier to sand, and probably will be smoother at the end.

I would try an orbital sander. You may still have to skim coat after, but probably won't be as extreme or need multiple coats of mud. Gardz plus skimcoating is a fine plan though.

I agree

Here's a link on skimcoating that might help you if you go that route. Don't use a topping compound but rather joint compound as it has adhesives in the mix that will help adhere along with the gardz. Another tip is to stay with the same brand of compound, don't mix with other brands as the mixes can vary between them enough to show where you stop and start. This is the mud I like to use if available in your area. It's a lightweight mud and although it is a topper, it has adhesives as a joint compound.

Here is a link that might be useful: skim coat.

Thanks a lot for your help!
We've got the sander, and it works a lot faster than I thought. Already sanded one corner, so hopefully we will have the appliances installed soon (living without an oven almost a year, lol). Is one coat of GARDZ enough?

sierraeast, thanks for advice and the link, this house is full of surprises, so I'll better learn how to skimcoat.

Sure, one coat is plenty as long as you apply a full coat. Gardz is very loose bodied so use a very short nap roller and you don't need to overload the sleeve. One dip goes pretty far if the surface is not that porous.
