1. I am gearing up to do some serious patching on 80 year old plaster walls. A book recommended applying a bonding compound, namely Plasterbond, before applying patching plaster. When I asked at the paint store, they recommended AnchorBond. The label doesn't even mention plaster. Is this the right stuff? I can't seem to locate Plasterbond. Would a primer like Zinsser 1-2-3 primer accomplish the same thing?
2. When sanding and refinishing heart pine floors, what is the best option for a do-it-yourselfer--a drum sander, orbital sander...? I have help from an experienced carpenter who has done this once or twice before (He's experienced at carpentry, not necessarily refinishing floors). Some time in the floor's sordid past, they were sanded to a somewhat desperate thinness in some areas. I'm hoping to be gentle, yet thorough when I sand!
