    Do I HAVE to paint over primer?

    I need to paint the walls of my new shop. The walls are OSB plywood. I've decided to use an Oil based primer. After buying the primer I got to thinking....do I HAVE to paint over the primer? I want white walls. The primer is white. Is there any reason that I HAVE to apply paint over the primer? I'm thinking two or three coats of primer and I should be good.

    on mine tom, i used the primer to seal the osb then gave it two coats of top coat which was semi gloss,, makes sweeping the cob webs off easier than a dull primer would..

    that's what I'm wondering about. I want as smooth of a surface as possible so if I need to paint I will.

    On metal yes because the primer is somewhat porous as this aids adhesion of the paint to the metal. Larry answered the rest as best I think it could be. I did the same with mine, primer and then two coats of gloss white. Makes it brighter and easier to sweep down.

    God and family, the rest is icing on the cake. I'm so far behind, I think I'm in first place!

    Well, I'm going to go the other way. I put 2 coats of Kilz II (latex) on my OSB walls and ceiling and left it that way. It has a slightly grey tint, but is basically white. I figured if I ever needed to paint, no problem. In 5 years I haven't found a need. Jim.

    Oh thanks Jim...now I'm totally confused... No seriously....Actually I think this was just my "cheap" side kicking in and hoping to save $15.00 on paint. God knows I've spent evough on this project already. I'll put the primer on and see what it looks like then make a decision. I got the last wallboard put up tonight so painting will be next but my work schedule has me busy non-stop for the next two weeks so I'm not going to get anything done till then.
