Even an old lamp with a bare bulb held close to a wall will make minor cracks, bumps or nail pops jump out. Carmen Toto, owner of C. Toto & Sons in Madison, New Jersey, uses painter's putty or a lightweight spackle for minor cracks and dents; he uses plaster of Paris for dents deeper than 1/8 inch. Instead of the standard tape-and-spackle method for bridging over recurring stress cracks, Maceyunas uses a rubberized spray-on primer called Good-Bye Crack. Damaged wood requires a slightly different approach. "Don't use spackle on wood," says Toto, "because it just won't stick." For damaged trim, he uses painter's putty or a two-part wood filler, such as Minwax's High Performance Filler. Smooth any repairs, bumps, and nibs with a drywall pole sander. For smoother walls and better adhesion, some of our pros sand all previously painted walls regardless of the shape they're in.
Only a dummy gets involved with so-called "contractors." Hire a qualified actual worker yourself. Check out their resume/background, etc. RULE #1..NO ADVANCE DEPOSITS! Pay daily or weekly or upon satisfied completion according your standard, not workers. Contractors are merely employment agents. If that's the way you get work done, then go ahead and waste your money and wind up with the myriad of problems enumerated upon in the news clip above. RULE#2.. NO SMOKERS. They are lighting up on your money. RULE#3: No cell phones while working. Talk on their own time after work
