No, not hard, but if someone doesn't know there's wax on a surface
they won't do anything to prevent the problem that will occur. Wax
interferes with the adhesion of any water-based coating. Silicone
interferes with water or oil based coatings. Wax is used in faux
finishing circles - in many circles - as a release agent. The wax
certainly will work to reduce stiction for sliding surfaces, and it's
not necessarily a big deal if the person who put the wax on is the
person who will be doing the subsequent painting. But very few
painters, pro or amateur, routinely dewax/degrease a surface,
particularly in this day of self-priming, sticks to gloss paint,
paints - and sanding doesn't remove all traces of wax. There will be
The OP said that he had casement windows, so there's really not a lot
of sliding going on. The problem is due to paint buildup. Over time,
paint build up will interfere with hinge and latch operations. The
best time to deal with potential paint buildup problems is before a
window is repainted. The operating parts should be checked for
clearance with a piece of paper. If the paper doesn't slide out
easily when the parts are closed, the window is too tight to repaint
without some sanding.
I've always figured latex paint takes a month to dry.
I did some metal garage doors this summer. Door sections have an overlap.
Left the overlaps separated and let dry for a day. Put petroleum jelly on
the joints. Worked out well.
