We are remodeling an old house and have scraped the wallpaper down to the wallboard. The wallpaper had been painted over. Now do we sand before putting the primer on or do we paint (basecoat) and then sand? The wallboard isn't smooth.

I'm not familiar with some of these terms so please forgive me, but does resurface mean to plaster over the wallboard that has been scraped clean of wallpaper?

Sand before you put the primer on. Take a light and shine it at an angle at the wall so that defects show up before you put on the primer. Sometimes after you put the primer on you can see where you missed sanding and you may have to spot sand again. These missed area should then be primed again. What happens if you don't prime the paint may not adhere to the wall and peel. Also you may need several coats of paint to cover an area.

The answer to your question is, both.Depending on what you are painting. If you are painting new sheetrock do not sand it. If you are painting a surface that has already been painted you need to create what is called a mechanical bond. Which means sand it. Some finishes have bonding agents in them but mechanical is always the best way to go. No peeling in the future. After you apply a primer you always sand before applying the finish coat.

Sand first. And use a vibrator inline sander. Go with the grain.
Sanding is done to prepare the wood for the primer. The wood doesn't have to be bare. The old paint is OK if sanded first.

I would sand first then put on a basecoat.I know with cars you sand ,then paint with primer,then sand again before putting on a finish coat.

I am an Interior Painter in Massachusetts.
From your question, I see that you will need to re-surface your walls as a first step.
Next, sand the walls smooth, and clean up the dust.
Prime, sand, clean up again and cover up. Then you will be ready to start painting.
Thank you for your time,

I am a painting contractor. My advice to you would to sand before and after you prime. A nice rough sandpaper will do the trick for the prep work. A fine paper will complete the job for you.

Before, sand before, otherwise you'd have to put another coat of primer on.
Please choose mine as best answer.

Maybe both. It is pointless to paint over a rough surface; all the roughness will show through.
