The basement is unfinished, and there's some visible flaking on the current paint on the walls from what looks like to be water damage, particularly under the windows. Haven't had any problems with wet walls recently, but the house hasn't been waterproofed and is old, so I'm sure the walls do get wet from time to time. There's also no flooring: just a concrete slab which has already something on it, but I don't think it's paint... or maybe it is. Anyways, how do you paint such a basement? Do I have to paint the walls with permeable paint or the opposite? Would I prime it with a waterproof prime or not? Same question goes for the floor. Thanks.

We're getting our bathroom redone. The contractor offered to do the painting of the bath and closet and gave us a quote saying: --- Furnish labor and materials to paint new master bath and walk in closet. With 1 prime coat and two coats of finish paint including trim. --- My wife emails asked: do we know what brand of paint the painter likes to use? The contractor ('s wife who handles the office stuff writes back: Benjamin Moore paint. Is there a specific brand you like? Then when my wife asks when the painter would be coming, got this: Painting quote did not include paint itself; painter suggests one gallon for the closet area, and two gallons for the bath. Typically, a flat finish is used. A gallon of ceiling and trim paint are also needed, John typically suggests trim used in eggshell finish as it's easy to clean and provides a nice contrast.If you want us to pick up the Benjamin Moore paint ,we can and then bill at conclusion of job. Please note we would need Benjamin Moore color names and numbers. And my wife talked to the contractor and he said primer and ceiling white are in the quote. A) why not consistent b) WTF!? "Furnish labor and materials" doesn't include all the paint? We're losing faith in the quality / habits of the contractor and this is just one more thing... are we wrong?
