Oh, where to begin? Let me start with 'watered down paint'. 25-50% before the material gets to the site? Impossible. You would basically be painting with water at that point. It would be less of a hassle, and cost, to simply use proper material. You would be forced to apply three coats instead of two, as the coverage would be horrible. Whatever cost you think might be saved in materials would be lost in labor.
Before the scrubdown, protect nearby plants by misting their leaves and saturating the surrounding soil with water, pulling them away from the house, and shrouding them in fabric drop cloths. (Plants will cook under plastic.) Lay more drop cloths along the base of the walls to collect any falling paint debris. Walls should be wet down before getting scrubbed, then washed with a gallon of water mixed with 1 cup chlorine bleach and 1 cup of either a concentrated, phosphate-free cleaner, such as a trisodium phosphate (TSP) substitute, or Jomax House Cleaner. Working in sections, from the bottom to the top, will avoid streaks. Be sure to rinse walls well before the solution dries. Wood siding and trim should be ready to paint after a day or two of dry weather.
I've seen this article sent out 4 times now. It's out dated in terms of today's "Scams." Paint stores haven't charged more money for deeper paint colors in over 15 years. Also Water downed paint? Seriously? That would never happen in the real world. And Wall repair? what painter would ever not assume wall repair as included? This article is a waste of time and should be taken down or edited to reflect actual scams of todays times.
If you decide to hire help, have several contractors inspect the job and provide proposals. You'll probably find huge price differences for the same job. A Checkbook undercover shopper got quotes from nine Washington-area contractors to repaint the walls, ceiling and trim for a living room, dining room, family room, bathroom and kitchen. Including paint and supplies, prices ranged from $2,650 or less to more than $6,500.
Second: all the tricks of the trade in regard to "cheating" customers is for hustlers and cheaters and NOT established businesses. At the end of the project the job should come out looking professionally painted as specified in the contract. A selected color that takes multiple coats that was not calculated by the contractor should cost more money. It's not the fault of the painter.
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.
