Hi all, I'm Eric, just registered on the forum tonight. My wife and I are buying a home which has paneling in the den. It's an older home, built in 1964, and there's no drywall behind the paneling. We want to redo the room and we're considering just painting, or texturing then painting. I've read about high-adhesion primers and how they're good for these types of applications. Now someone smack me over the head if I'm way off base, but what I'm considering (if we go the texture route) is to roll on a coat of high-adhesion primer, then go in with some mud to fill the small grooves in the paneling, which is not real wood. Once that's done, I was thinking of applying mud all over and doing a knockdown texture, then painting. Does anyone have any recommendations for the best type of primer? Are high adhesion primers really better for this type of use? Thanks for any replies!
