My newly purchase house has a Cigarette smoke from the previous owner. Ozone treatment and duct cleaning is done, it helped but still smoke is there. Next step is I am moving to get house paint with Zinsser or Kilz primer. Can someone point me extact product I should look into since there are many version of it. I could Kilz Restoration Interior Primer but not sure if this is going to work or should I look into Zinsser. Please advice.
