I have recently uncovered an old (and presumably original circa 1930) hardwood floor in the hallway of my house. Over the past couple of weeks I have been cleaning and sanding it in order to re-varnish (or most likely wax) it.
I have not been taking any special precautions about when sanding the floor, over and above using a face mask, gloves. It was my understanding that old paint used to have lead in it, but that old varnish didn't. Is this the case?
Is it likely that there is lead in the varnish of my old 1930's hardwood floor?
