Clear, Zinsser Odor Killing Primer- 5 Gallon, 1 Per Pack

Primer is excellent for what it does-killing smells-all of them. But don't expect it to do anything else, dries clear and your walls or floors are going to look absolutely like they did before you coated them. We bought a house where the owner went to the nursing home so the place was pretty much left as is. After removing all the 40 year old carpet, the ammonia smell knocked you down. Dog urine and feces, mold from leaky pipes , mouse pee, you name it. Scrubbed the plywood subfloors, replaced all the plumbing, moldings, ; and put the primer on and it cured the stink. Couldn't believe it. Also applied it on all the floors as well as the bottom 2 feet of walls. Let it dry, then used regular primer for stains. Would definitely use again. Only issue we had was having buy two products. I would pay more for the odor killing primer if it also covered up the other normal stains that get primer and it would save a lot time getting your project done.
