Painting bathroom walls
Hello
We just bought our first house and are doing a small renovation to the bathroom. We want to paint the wall, took out the vanity, mirror and there was paper on the wall.
Now it looks like this, I know we need to patch the holes with joint compound, sand it then put prime on it. But what do we do to this area that was covered with wall paper? Do I put joint compound all over it ?
Please I need help, this is my first ever project for this house, I’m excited but stressed too 😭😭
