Help on repainting paneling
We have wood paneling (tongue and groove) in our house. At one point it was either stained or polyurethaned or something. Years later, someone painted over it with latex paint (rubbing it with denatured alcohol took it off, so that means it's latex, right?)
We now need to repaint it all because some of it is affected by a renovation and it's time for a color change anyway. For the most part, even though it was never primed, it has help up well (it is on one wall and then used as wainscotting on the other living room walls, in the hallway and an additional room). However, even painters tape will pull the finish off.
So the question is, what steps should we take when we repaint. Cleaning it with Dirtex was one of my first plans. Should we prime on top of the existing paint? If so, with what primer ... Zinsser 123?
Please tell me we can get away without sanding it.
