i've got some furniture i've been dragging around most of my life. i figure, might as well keep on using it, nothing wrong with it, except it looks it's age. i'd like to paint it before moving to the new house. past attempts at painting furniture haven't been anything to write home about. because of an allergy, it ideally should be latex (not oil based) paint. would it help if i sanded down the furniture first? i really don't have time or energy to completely refinish them. they're not really worth the effort either. a coat of a nice dark brown paint will suit us both. so, can i like rough up the old paint/ old finish with sandpaper, or a sanding disk thingy on a drill? then paint? will it stick? help? please?? thanks all!!
