Is kilz just a primer or paint too?

KILZ is primarily known as a primer brand, but it also makes products that are paint, and paint plus primer combinations, so it is both primer and paint depending on product line. The original and most famous KILZ products are primers designed for stain blocking, odor sealing, and adhesion, not as finish paint. These include KILZ Original oil-based primer for heavy stains, smoke damage, and pet odors, KILZ 2 All-Purpose latex primer for general use, KILZ 3 Premium for superior hide, KILZ Restoration for maximum odor and fire damage blocking, and KILZ PVA for new drywall. These primers are meant to be top-coated with finish paint. However, KILZ also makes products that are paint: KILZ Upshot is a ceiling paint, KILZ Pro-X is a professional line that includes both primer and finish paints for commercial use, and KILZ Complete Coat is a paint and primer in one for interior and exterior walls that can be used as finish paint. Additionally, MasterChem, which owns KILZ, sells KILZ as part of Behr family, and some KILZ products are labeled paint and primer. So if you buy KILZ Original, you must topcoat it; if you buy KILZ Complete Coat or ceiling paint, it can be used as paint. Always check label to see if product is primer only or paint plus primer.
