Acrylic latex paint. Make sure you lightly sand to remove any gloss. Prime with a good stain blocking primer. Then paint. Seal with at least three coats of a water based polyurethane.

I have just used eggshell pure white water based paint on a old wall unit, when it dries it’s hard wareing. Also it don’t discolour like gloss paint.

I love chalk paint because it requires minimal prep. Clean your surface well and apply the chalk paint- couple coats is usually sufficient. Top with wax or polycrylic to protect.

I've never used chalk paint. How does it hold up to wear? The name makes me think it will chip off and/or show scratches. Or is that the point?
