You've got me very afraid now, I've been taken in a couple of times since I moved here. They take advantage of me because I am a single woman, not exaggerating! From gardeners to inside work. Wouldn't have house painted but I know my HOA will be after me soon, garage door is peeling and stucco needs repair. Got the $1500.00 deal, but paying more for extra work they say I need.
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.
If you’re trying to save money, but still want some professional help, consider clearing out a room prior to the paint crews showing up. Removing furniture or climbing over small obstructions can increase the amount of time necessary to finish a job & ultimately increase overhead for a paint crew. Do yourself (and your painters a favor), clear anything out of a room that you don’t want painted.
I agree with JHs. If there is no new color on it at all, just talk to the painter about it, if it was an honest mistake (which can happen very easily while painting) your painter should have no problem fixing it. However, in my years of experience, it is not unusual for 2 coats of door paint (good quality) not to cover very well at all. I once painted a red door 7 times, plus a tinted prime coat before I found the door to be a solid color.
