What to use instead of Kilz primer?

What to use instead of Kilz primer? Instead of Kilz primer, you can use other primer brands with similar stain-blocking and adhesion properties. Popular alternatives include Zinsser Bulls Eye 1-2-3 water-based primer, very versatile and good stain blocker, Zinsser Cover Stain oil-based for heavy stains and odors, similar to Kilz Original. Behr Drywall Primer, Glidden PVA Primer for new drywall, and Benjamin Moore Fresh Start are good for general priming. For severe smoke or water stains, shellac-based primers like Zinsser B-I-N shellac primer are considered strongest odor and stain blocker, better than Kilz for fire and smoke damage. For mold, use Zinsser Mold Killing Primer. For exterior wood, use oil-based exterior wood primer. If you want eco-friendly low VOC, use Benjamin Moore or Behr low odor primers. Choice depends on surface, drywall, wood, masonry, metal, and stain type. For light drywall priming, PVA primer is cheaper than Kilz. For heavy stains, oil-based or shellac is better. Always match primer to topcoat, water-based primer under latex paint is common and easy cleanup.
