Background: I have some walls that were once covered in wallpaper and my wife and I removed them when we bought our house. We then casually patched and sanded some of the blemishes left by the wallpaper removal and painted the walls with some Behr paint that was a combined primer and paint.
I have come not be annoyed by what you see in the album, which I believe stems from my lack of prep, mainly knowledge about the best order to approach these things. Per the DIY guidelines I have done some research about what the proper order I should have followed while painting but many sources seem conflicting/personal preference.
Here are my main two questions.
Is there anything I can do to fix the problems seen in the photos?
When I paint my next room, would the following be an acceptable approach?
If there are any resources that you have tried that show the correct way, I would appreciate that too, I can't tell the difference between most people's personal preference online.
