We stripped wallpaper off our bathroom wall and found that the builder did not size up the wall first, he papered directly onto the drywall. We have sanded the drywall best we could to try to smooth out the parts where the drywall paper came off with the wall paper. I am trying to paint it with flat paint that has a primer in it. First of all the color is a lot darker than what is in the can and secondly it won't adhere to the trim areas around the cabinets. There appears to be some sort of spray on the wall. They also caulked around all the cabinets. Any advice?

  • Is the drywall paper still on the drywall? What are you looking for advise on - seems like you have a few different issues.

  • @DMoore - Yes but it is uneven because some first layers stuck to the glue of the wallpaper when we too the wall paper off.

  • @DMoore- We have not got down to the Sheetrock under the paper. I thought a just had to prime the wall before painting it. The guy at the hardware store told me I could do both priming and painting all at one time with the paint w/primer

  • Do I understand you have drywall with some wallpaper still stuck to in spots?

    The reason it won't adhere is probably because some of the glue residue from the wallpaper is still on the wall. I had the same issue on a bathroom wall I painted recently. I used sanding and spackling to deal with it after getting as much of the glue off as I could. And, you definitely should use drywall primer first. You'll regret it if you don't because it contains some chemicals specifically for plain drywall that paint/primer combinations don't. Plus it makes painting a lot easier.

1 Answer 1


I think you missed a really important step in the process. Anytime I have to remove paper from walls that were not treated with a release sizing before the paper was applied, the drywall paper is usually damaged or lots of glue residue is left behind. I have found that a skim coat of drywall compound needs be be applied, sanded and sealed with PVA primer before painting can be done.

In most cases, a self priming paint is only effective on previously painted walls, but never on new or bare sheetrock. The primer in those paints is designed for hiding old color, not sealing new sheetrock. New rock, skim coated rock, etc., need to be sealed with a quick drying sealer like PVA primer. This type of primer seals the porous surfaces and prevents the moisture in regular paints and primers to soak into the drywall.

The skim coat is actually the key step you missed. do not use untreated regular drywall compound for this job. Modify the mud with a bit of water and some Ivory dish liquid. A gallon of mud with an ounce or two of water and a couple of tablespoons of Ivory is a good formula. Mix well. It will be loose, almost runny. You will find it flows on very smooth without a lot of bubbles with a 8 to 12 knife or trowel. After it dries (8 to 12 hours), sand lightly with a 220 grit sanding sponge. Touch up any areas that still need attention, dry and sand. Clean off all dust with a slightly damp sponge, let dry then seal with PVA primer. You can usually paint in about 2 hours after PVA.

As for the caulking you mentioned, remove as much as you can with a stiff one inch putty knife. Mineral spirits will usually remove remaining residue from the wood cabinets. Remove all of the caulking from the drywall with your knife, even if it takes some of the drywall paper with it. You can repair the divots in the rock with the skim coat as described above.

  • Thank you everyone for your input. I'll be back if it doesn't work.
