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.
Excellent advice because there are many unskilled workers who are "trying to pull the wool over the customers eyes". One has to study about the project for which they are in need. I happen to need dry wall repair and painting done in my home and feel the advice in this article will be a great help to me in hiring someone who is ethical and does good work. Thanks.


House painting is important for many reasons. Obviously, a good paint job beautifies and adds character and personality to your home. Just for that reason it’s important to take sufficient time planning which colors, shades, and paint styles you want to decorate your home with. But paint also serves as one of your home’s primary lines of defense against weather, insects and other damage, so it’s an important aspect of home maintenance to keep up on as well.
As you scrape, you may find that the wood has turned gray or black in some areas. Check for rot by probing these areas with a nail. Spots that are discolored but firm are simply weathered. Weathered wood doesn’t hold paint very well, so sand away the gray surface. If you find soft areas, you’ve got rot. Small, shallow soft spots can be dug out and repaired with a two-part filler such as Minwax High Performance Wood Filler. But when rot is deep and widespread, it’s best to replace the entire piece of wood.
If you don’t have any lead in your paint, then it’s time to start scraping. Begin with a hand scraper to remove all of the loose paint and tight spots. For larger easy to reach areas, a rotary sander is the tool for the job. You’ll need eye protection and a respirator. The sander is powerful, so you have to be careful not to damage the wood while removing paint. Any paint that is cracked, blistered, or peeling needs to go. Next, smooth the transitions from the bare wood you’ve revealed to the existing paint.
• One room or the whole house? Applying one coat in one room is a reasonable DIY Saturday project (especially if you have help and beer). Multiply the time spent moving furniture, prepping walls and sanding old trim by the number of rooms in the house, and you might want to hire real help. It's the same outside. You can probably tackle one shady garage wall that needs a little scraping and sanding plus a coat of paint, but covering all surfaces of the house is usually best left to a pro.
