Face nailing boards
How can I tell whether stainless steel nails were used to face nail my hardwood floors at the perimeter? I read that using steel instead of stainless creates black marks when exposed to any moisture. I guess they would also corrode over time if you damp mop or wipe your floors down. Would high humidity also be a problem with the blackening?
How can I tell if he used a finish nail or just the same nail that was in the gun he used for attaching the floor to the subfloor?
