It looks like the walls in my house have not been painted again since the house was built in the early 90s. Not sure if the interior paint is oil based or water based? It looks like a satin finish. I've primed before in other rooms before painting, but I am wondering going forward if I should prime anymore because it's an extra step that requires work and Sherwin Williams Duration says its a paint and primer in one.
If I use Duration Matte over Satin of unknown paint brand should I prime it first? What primer is best to use? Thanks!
