How many coats to repaint the interior? I just bought a new house but I want to paint different colors. It is currently white. Should it be 3 coats or 2 coats or how many coats?
It depends on your colors, and on your stroking. Warm colors do nice on white, and if you brush carefully you will see beautiful artistic strokes.
If you buy good paint, you should be able to do a good hide in 2 coats. But it depends on the darkness of your colors. Off-white will do in one coat, dark red will need maybe 3.
