Kilz over old oil based finished exterior ceiling yes or no

exteriorpainting

Can you put water based kilz over an old exterior ceiling that was finished with oil paint 20 yrs ago ? I want to put a latex finish on it and I want to seal it with kilz 2, is it ok to do this ?

Yes you can, but you will want to ensure the existing old oil-based paint is properly deglossed and clean to ensure a good bond with the water-based Kilz.
