With that said, here's the reality of that particular scenario. Painters do put water in the paint, but not for reasons you would think. Some materials need to have their viscosity manipulated in order to slow drying time, allowing gravity to 'smooth' out the product for a better finish. It also prevents 'drags' and 'sausages'. I personally try not to do it too often, but from time to time I have to. I want my client to have a proper finish.
I put out a request for bids to several local house painters and quite a few seemed high. One was for over $6000 for painting the exterior of the house with putty fill as necessary, paint included. It was for him and one other guy to do the work. I said, "it's going to take you guys quite a while to get this job done" and he told me that no, they could do it in 2 days. I don't know about you but $1500 a day per painter seems more than just a bit high. I went with someone else and they had several people there for several days working like crazy and did a great job. There are too many scammers.
If there is any peeling — and there usually is somewhere — it's essential to scrape off any loose paint. This doesn't just mean the parts that are already separated from the wood and ready to fall off on their own. Each spot where paint has peeled loose needs to be scraped thoroughly until you can no longer get the sharp corner of a putty knife under any of the surrounding edges of paint. Then, the bare spot needs to be sanded until the paint edges are smooth.
Interview your contractor.Before you choose a contractor, get three bids for comparison and ask the right questions. Bunting says you need to know the following: Do they have proper licenses, insurance, and bonding? Do they subcontract the work out? Do they offer written guarantees of their work? “Recommendations from friends and family are always a good measure,” adds Rance. “And ask for references from previous customers.”
To determine how much paint your house needs, measure the house's perimeter. Then multiply that figure by the height, excluding gable ends. Take the measurements with a steel tape measure, or reel out a ball of twine around the house and mark and measure the twine. If you will use a different paint on your home's trim, subtract 21 square feet for every door and 15 square feet for each typical window. Divide the final figure by the square-foot coverage specified on the can of paint to determine the number of gallons you will need for one coat.
