(1)if the existing is of sound then patch in first then slurry the hole area, i use a s/c and pva, i take it that existing is painted? once slurryed i would put a basecoat 3/1 waterproof scratch,(2) if the existing is of poor then take off the top coat back to a sound backing , prim as described and cont...... hope this helps! the second option is proberbly the one i would use.
