Can you use drywall primer over a previously painted surface?

Hello





I was wondering if new drywall primer can be used to prime an already painted surface. I need to do some painting on a wall that will require some priming, and I have lots of new drywall primer left from a previous job.





Thanks!Can you use drywall primer over a previously painted surface?
Yes you can. Primer is primer. Just be sure to prime the whole wall so the paint matches afterwards.Can you use drywall primer over a previously painted surface?
will work like a champ, if the paint on the wall now is not a high gloss paint ( really shiny )


Hope this helps.
