Painting After Removing Wallpaper
We have removed most of the wallpaper in our condo. The wallpaper was there for at least 30 years. We used DIF and boiled water to get the wallpaper off. We then cleaned up the wall with more DIF, hot water, and a rag. We also spackled in some parts of the wall that clearly needed it. Then we used a primer and then painted with a high quality paint, Benjamin Moore.
There is a problem with several walls but I’ll deal with one since whatever is wrong with one applies to all. When we face the wall and look at it, it looks good. The problem is that when we look at the wall from a side angle, parts of the wall look blotchy. We have already painted the wall several times. Does anyone know why this is happening? Does the blotchiness occur where the greatest amount of glue had been put on? Does it occur where the surface is rough? Do we need to spackle the blotchy areas so that it has an even appearance from all angles? FYI, we do not want any more wallpaper.
Some guidance would certainly be appreciated.
Thanks,
Robin

Welcome to the forums Robin!
What kind/type of primer did you use?
It is always best to remove all the wallpaper and all the glue. If 100% of the adhesive isn't removed, you should use either a solvent based primer or zinnser's gardz primer.
Probably the best fix at this point would be to sand down the 'blotchy' areas, repair with joint compound [spackling will work on small areas] and repaint.

The blochiness can be caused from either of two things:
1. Suction spotting where the paint draws into an unsealed or poorly sealed substrate. This may occur where there was glue left on the wall. Latex primers are not the best primer for post wallpaper removal. Solvent primers seal better and prevent any glue residue from being re-wetted by subsequent painting.
2. Textured areas will look flatter (in sheen) than smoother areas. The texture breaks up reflected light, the smooth areas will reflect light better. Since this is noticeable on an angle, this may very well be the problem. If you smooth out the textured areas, you will need to re-prime - probably the whole wall before repainting for best sheen uniformity.
