Buying a can of premium paint, then bait and switch over to low-line products? Again, complete nonsense. Think about it for a moment; the Painter needs 5 gallons of wall finish. So, he buys one can of premium and the rest 'cheap'? How is he going to hide the 4 other gallons? What's he going to hide it in??? He only has ONE gallon of premium. It's not as though he's going to keep older can labels, they would be covered in paint of a different colour.
So sad that Angie's List requires the contractor be notified!! They have lost me as a client. If I'm dissatisfied and want to give an "F" rating (question/workers...I SHOULD NOT be intimidated into passing up an opportunity to explain my experience! There is NO WAY my contractor got an Aplus rating from over five hundred people....so someone was lying....yet I can't report that without the contractor knowing it? REALLY?
Second coats on similar colors are almost never recogicnized as being needed until the coat is applied and has dried. ONLY THEN WILL YOU SEE WHETHER IT NEEDS A SECOND COAT or not. Yes, painters can use a cheaper paint then what you paid for. That is solved by getting your own which, I would charge extra for because I will always have to go get more, or add second coat because home owner tried to skimp on paint, or they got the wrong color etc...
I'm an architect and my firm routinely specifies interior finishes for projects so I thought I'd contribute a professional's perspective on the issue of how many coats of paint are deemed "acceptable". The fact of the matter is the average consumer usually isn't a paint expert and can't be expected to know about all the factors that impact coverage. That knowledge is considered "means and methods" and in a court of law, the responsibility lies with the painter or general contractor, not the consumer. What the consumer should be concerned about is the final result-does it look good and is it what you expected? The simplest way to communicate this to your painter is to stipule in your written agreement that the number of coats will be "as required to cover". That way all the guess work about what kind of primer, how many coats, how color affects the scope of work, etc., is removed from the consumer's responsibility and resides where it belongs-with the professional. In the contract that's why retention is always a good idea-typically 10% is withheld from payment until the job is completed to the satisfaction of the customer. Of course in return you as the customer have to be reasonable about what constitutes a completed job. Just my $.02.
First off, the picture on the top THAT IS A HOME OWNERS PAINT JOB. If you here a school kid or your neighbor, this is what you get. I was a painting contractor for the better part of 40 years and never saw a PAINTER (even the worst painter) leave a mess like that. Maybe the electrician or the carpenter but, that is not something a painter could even do if they tried.
