Take the 2-minute tour ×  I am wondering if the paint
contractors painted my new drywall appropriately. It is a flat
latexand if even brushed with a damp towel it darkens. It seems
to me that the drywall must not have been sealed properly for
water to be absorbed like that. Can you advise me?
share|improve this question  1 Answer 1  Assuming the paint
returns to the original color once dry, this is perfectly normal
with flat latex paints. When I wipe my walls, the spots that I
wipe look darker too.  You can observe this on many surfaces,
even inpermuable ones like glass and metal - ever notice that
your cars paint looks different when there are drops of water on
it?  share|improve this answer Mine look lighter with dark
colors. Always happens when grabbing a towel with wet hands. –
