My house, a 1950s rambler, is built out of concrete block. The previous owner used heavy triangular nails to attach his baseboard to the plaster over concrete block interior walls. This method cracked the oak baseboards and left large holes in the plaster behind the baseboard. I'm looking for a method, perhaps drilling a small hole and inserting an anchor in the wall to attach my new oak baseboards. I think that glueing using a PL product would be difficult as I would have to brace the glued baseboards from across the rooms and hallways. Does anyone know of a drill and anchor method? Thanks very much for your advice. Steve Arnold
