What preparation is necessary on the walls & ceilings before applying
an orange peel texture?
Walls: they currently have a painted knock-down texture. My contractor
wants to spray an orange peel texture directly on it, but I'm
concerned that it may not hide the old texture well. Will it work?
Should I have him apply a skim coat of compound on the walls first? Is
a primer needed before texturing?
Ceiling: after removing the old popcorn texture from the ceiling, it's
left with bare wallboards (unprimed, unpainted). Again, my contractor
wants to spray the o.p. texture directly on it. Is a skim coat
required before texturing? How about primer?
Bullnose: my contractor bullnosed the wall corners, and his job left a
lot of metal exposed. He wants to spray the o.p. texture on it
directly. Will it stick? If not, what goes on the metal before
