I ripped out the carpet in my old home (with the intention of refinishing) to reveal old wood floors which have been shellacked. No biggie, but the problem is the prior owners face nailed every #*&! board to every joist using common nails! They are also very splattered with white paint. After consulting some pro's the floors cannot be saved. SO, my plan is to paint them white. Sacreligious, I know, but I cannot afford to rip them out and put new ones down. My question is, what is the best primer to put over the wood that will also stick to the nail heads... I was looking at Zinsser, but I don't know which one to choose. Also, any advise on a durable brand of floor paint? I would prefer to stick with water based paints. Sorry for the long post, thanks!
