I think that watching 5 coats of paint dry would just about suit me. :)
But actually painting something 5 times wouldnt :-?
But as for all that hard work messing about with water and fillers :(
Just use Yeso on the inside,it dries to an almost white finish  8-)
And use whatever colour monocapa on the outside and never paint again ;D
Hey its called PARADISE ::)
As for limewash, I wouldnt even put a lime in a drink, yucky stuff :-?
