Spills and spatters happen, regardless of how careful you are. It’s a lot easier to pre- pare for them than to wipe them out of your carpeting or off your wood floor later. All it takes is canvas drop cloths in your work area (a 4-ft. x 15-ft. cloth costs $15). The thick canvas stays in place, so you don’t need to tape it, and you can use it to cover any surface. Plastic drop cloths are slippery to walk on or set a ladder on and don’t stay in place. Even worse, paint spills on plastic stay wet, and they can end up on your shoes and get tracked through the house. Canvas is slippery on hard floors, so rosin paper ($10 for 400 sq. ft. at home centers) is better over vinyl, tile and hard- wood. Tape the sheets together and to the floor to provide a nonslip surface.
Repaint — exteriors especially — before visible signs of wear appear, Bancroft says. Don’t wait until you see peeling or flaking paint. “If I have to spend 40 hours preparing the surface before we can paint, that time is going to result in a lot of extra costs. But if I can spend 10 hours preparing the surfaces to be painted, you’re going to save money,” Freeman says. https://www.youtube.com/v/b6_WEt9k_Hw&feature=kp
I managed commercial construction projects for many years, have built and remodeled several properties, and never once have I encountered any of these scams. The tone of this article is deeply troubling. The author seems to be saying that ALL painting contractors are inherently dishonest, and that has not been my experience. The underlying advice here is sound: get it all in writing and cover as many contingencies as possible--so pointing out potential pitfalls like coat coverage is helpful. But do that in the spirit of clear communication of expectations, not with the expectation that the person you are hiring will try to cheat you at every turn. Not every contractor takes outrageous advantage of change orders; not every contractor will sneak past necessary preparation and/or repairs. Contractors of all sorts get a bad rap as it is; reinforcing a stereotype with articles written from this point of view just seems unproductive.
