This has been a sore spot for my entire career. I watched one painter roll a ceiling over a finished floor with NO DROPS. I asked what the hell he was thinking. He said, "well, I thought you had to sand it for another coat." Meaning,
you can sand off my paint. I nearly went crazy. This happens time and time again. Painters are generally the most stupid and inconsiderate trades on new construction. I tell all clients, in writing. I am not responsible for repairing any damage to their floors after the flooring is installed; not just completed. Another story. A "painter" was painting the wall on a stair case. So he cobbled together a scaffold using a plank and a 5 gallon bucket of paint. The pail of paint was nearly full and had been opened, so the lid was not very secure. Of course, he falls and knocks the bucket of paint over, where it proceeds to get all over the new floor, which had not been sanded yet. Well, if you know oak, the paint gets in all the grain and between the boards. Not salvageable. Had to be torn out and re-done!
I have dozens and dozens of other stories. How about the painters cleaning the newly finished wood floors using Goof Off. Well, that's a fine acrylic paint remover. It works good at removing floor finishes as well, which is what they did.
I'll work with a general who's painters screwed up my floors ( which are mine until I'm paid in full ) agreeing to repair them, but not for FREE. Exception, a few splatters here and there, ok, that's not a big deal. Removing overspray, tons of splatter, big drops everywhere; that I'm not doing for nothing. So here's a tip. Removing paint from floors is usually much more difficult ( and expensive ) than removing the small amount of dust created during installation and finishing of wood floors. So get all the painting done first! And make sure the touch-up guys know the floors are done. I watched one "painter" wandering around with a can of paint and a brush, doing touch ups. He was oblivious to the fact that his brush and paint can were dripping paint all over the wood floors and carpet. Ah, what a pro!
