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.
we only use the best interior paint which goes further as far as pricing a repaint we charge 2.00 a square foot floor space for walls ceilings and trim .on new construction using the best paint 3.90 per foot floor space that is with 3 coats on all surfaces but as being a professional for 45 years i recommend use a professional so that your paint will last longer and you wont have to pay to have it done more often i do free consulting in these areas i am more than happy to assist you with your projects 864-506-6666 just always remember good paint last longer and use a washable paint your home is your most valueable investment take care of it
I am in northern Nevada and you have not yet gotten sufficient responses to provide a painting cost chart showing the averages. I do have a quote from an outside (Not Homeadvisor referral) painter who is local for $2,750 for soffits, patio cover and posts, Garage facia (redwood clapboard above (~300 ? Sq. Ft.) on a 2046 Sq. Ft. home where the walls are 9 ft tall and it is fully stuccoed with plastic stucco surfaces, so not being painted.
