Though the colour he recommended is TOTALLY NOT the colour of our other walls (vibrant orange as opposed to pale yellow, the latter already there as a colour). The effect is okay and it certainly looks like a  cleaner job than without paint on top of it. Such a contrast of colours though: it is a screaming difference! ah ah ah. We will get used to it. It is really just a detail and not a big deal whatsoever.  It is so not our colour of walls. Very flashy orange. But I like that we do it nicely and cheaply and with good people, good workers. I had a bad experience with a sleezy insistant plumber recently, but these guys for general construction work are excellent on that front. Not a single worry about being  cornered by them, unlike the sleezy plumber. .
