I've a solution, but it's quite hard to obtain:
all you need is a bit of plaster (not plaster of paris, but [STUCCO]), please find a translation in english.
if you put a 1 cm layer of this on a surface, it should dry in around 2 or 3 days. but if you let it dry on the sunlight, it should dry really faster on the surface, leaving this kind of effect...
it happened lots of times to me, but I didn't want it!
