When a painter gives a price quote on sculpture the walls in a room, ( previously painted next to offwhite latex from builder, new paint is to be slightly dark beige shade) how tons coats of paint would you expect that to include. A primer coat and 1 or 2 finish coats? or just anything makes it look obedient?

What is the standard unless otherwise specified for professional housepainters?

Thanks for your input.
Answers:    The painter's responsibility is to produce a "properly painted surface" which is defined as "a surface that is uniform surrounded by appearance, color, texture, hiding and sheen" (as defined by the nationally standard standards of the Painting and Decorating Contractors of America - P1-04 standard).

In practical terms it channel the painter should be quoting the job to do it "properly" - not partly done. Usually hiding can be achieved contained by one coat with illustrious quality paint , but drastic color change may take two. Sheen uniformity is the other leading component of a good paint situation. Sheen paints (satin or semi gloss) will usually require two coats for good sheen uniformity especially if here was any patching done or if fine art is being done over poor characteristic "builder's flat" paint.

Additionally, if you want primer plus two coats of paint (because you feel that it would be more durable etc..) you can specify that and require the painter to quote a price on priming later painting two coats. If you are the homeowner and buyer, afterwards you can specify how it is to be done - because you are "footing the bill".
Good Expensive paint - light over bedside light - two coats
light over cloudy 3-4 coats
