I got some MDF board cut to size yesterday to put up in my cupboards as additional shelves. Do I need to seal the MDF or is it ok to leave it raw? Mostly going to be holding boxes, bedlinen, and canned/boxed food stuffs.
I know you’re meant to seal it if there is a chance of it being exposed to humidity, but I’m expecting them to be pretty dry with the exception of an unexpected leak.
