Thank you - What is your opinion about the dust from the floors on my newly painted walls?

You can carefully wipe down the walls. Its all part of construction. Most modern sanding systems use a HEPA filtration system though so the dust should be minimal.

Either way. It really depends on how careful the flooring people are. Some are kind and others are animals.

For the dust on walls I would use a swifer dry mop and just "dry mop" the walls. Keep changing the swifer pads until there is no more dust/dirt on them. Or use microfiber cloths clipped into one of those swifer mops. Lower section you can do by hand, but the swifer mop will help with higher wall areas.

"Tom Silva replies: You can do it either way. My painting contractor, Jim Clark, wants to be last so doesn't have to repaint baseboards that have been splotched with stain or ployurethane, or nicked by a sander. Besides, even the most careful flooring contractors inevitably leave a film of dust everywhere, he says.

My flooring contractor, Pat Hunt, sees things a little differently. He prefers to be last because floor finishes take a while to fully cure, so he doesn't want anyone walking on them even when they're covered with protective tarps. He also says it's pretty common for other contractors to damage or spill stuff on a finished floor. The way he figures it, it's much easier to touch up paint than a floor finish.

As the general contractor, I sometimes have the flooring finisher go first, and sometimes I let him go last. It all depends on what's best for the project schedule. I have that kind of flexibility because I know Clark and Hunt will put a lot of effort into protecting the other guy's work."

I like Mike's answer on previous houzz post.

Mike "I am a painter by trade. We do this every day. Paint everything but the baseboads first.

Have floor guys site protect base and stairs or anything else that may get stain on it by accident. Have painter come back after floors are complete to paint base and do any minor touch ups. The last thing you want is painters walking around on your newly finished floors dropping tools and sliding ladders. Remember,the new floor clearcoat takes time to cure. It will be soft and easy to damage until it cures. Hope this helps."

Sounds like a good plan for your situation Dyan!

My advice usually mimics what I read above, paint the walls first, do the floors, then paint the trim (base, casing jambs and shoemold) last. This minimizes the work on top of the freshly finished floor, though a skilled painter should have no issues protecting it. Painting is done far more often than floor refinishing, so painters should be used to protecting finished surfaces.
