A few years back I "antiqued" some walls in an apartment by using beige and yellow colored backgrounds (2 separate rooms) and then brushed straight glazing over the top to soften and antique. The apartment has been rented the past few years and I need to touch up the walls after an upcoming move-out. Should I decide to repaint in a plain same or different color with no glazing, can I paint directly over the old glazed wall or do I have to remove the glazing, or cover the glazing, with something prior to painting?

Thank you kindly.

I would sand the wals to dull the sheen of the glaze and wipe off the sanding dust. Then you will want to prime the walls with a bonding type primer such as Zinsser 123 and apply your finish paint over that. The reason you need to do all of this is a glaze is very much like a varnish and can be hard to get paint to stick to it.
