I have started on the walls, the wallpaper just flakes off,except where the glue is. So I had to sand it off. I spackled the walls, let them sit overnight and gave them a good sanding the next day. I am starting to prime the walls now and they are sucking up the primer. !!! Even after a coat of spackle. I'm still working on the foundation, still have a few pieces to prime. Then to decide how I am finishing that. I am thinking of cement blocks, gotta go measure them on my real house before I start though. The porch will probably be painted gray. That is as far as I have planned so far. I have no ideas for the exterior color or finish.
