My Ex let her eight dogs ruin the carpet in my trailer. The New and Improved Mrs. Plant gags when she goes in, though we’ve pulled up some of the carpet. Will removing the carpet and laying tile get rid of the stench?
You need Fabreeze.
It depends, literally, on how deep the damage went.
If we’re talking urine, it may have soaked through the carpet to the pad and into the subflooring. If so, you’ll probably need to tear that out and replace it. Ripping out the carpet and pad and letting it air out for a while will give you an idea of whether you need to go further.
Then you need to get rid of the stench of Febreze.
You’ll really need to remove the carpet and pad, then assess whether the smell has entered whatever was under the carpet - probably plywood. Plywood is, unfortunately, porous. If it’s still stinky with obvious stains, hit the stains with Nature’s Miracle and conspire a way to keep the treated areas damp for a few days - the stuff needs to stay wet in order to work. If it still smells, get a black light (pets shops sell these as “stink finder” lights to find the remaining organic contamination and re-apply Nature’s Miracle as needed.
If there’s a really bad spot, you may want to consider replacing that area of the subflooring, or if things got to the “Call the Health Department” level, replace the whole expanse. This is the pee stain version of “nuke it from orbit.” Expensive, disruptive, but almost guaranteed to be 100% effective.
Just laying tile immediately after taking out the carpet may result in still smelling pee once the smell of new tile has dissipated. Then, you’re faced with living with the lingering stink, or ripping out the new floor and trying again.
If the subfloor is saturated with urine, Kills Paint/primer will stop the odor and I think there is a variant that tile mastic will adhere to. Good luck
helpful nitpick -> I am pretty sure the quoted brand-name should be Kilz. Its my go-to brand of ‘primer’ but I have no experience with it eliminating odors, fwiw. Just wanted to make sure OP knew the right spelling should they go look for such a product 
HTH
This is what I was thinking. I wouldn’t do just this, though. Get it to where you think it’s good, then do the Killz as insurance.
Oops you are correct:smack:
Kilz will work as you’ve said. Most likely any tile will be laid over something called “magic board”, or at least that’s what they did in my kitchen when I added tile to a ply floor. I have no idea why that was necessary, but they refused to lay the tile over the bare ply.
Plywood flexes too much to be a suitable base for tile.
Vinyl tile.
And it’s particle board. With staples. Replacing that would be another “help me!” thread.
I’ve had the same problem. First we ripped up the carpeting and padding. There were some areas where the staining was so bad that the plywood/strandboard had warped and needed to be replaced. For the rest of it, we put down Kilz, and then recarpeted. Smell gone.
There are very effective specialty products for removing odor and others for sealing. Probably won’t get them at Home Depot or Lowes. Check the shops that sell to pros, both for cleaning and painting.
Here in OKC, I went to a place called A1 Vacuum and Cleaning Supplies to get a product for removing pet odors from concrete. Then I went to H.I.S. Paint for a concrete sealer that I could use under carpet and padding.
AR has similar places, I’m sure. Of course, you’ll be asking in regards to wood. Be sure to tell them you are putting vinyl down afterwards. It could make a difference in exactly what product to use.
Sometimes, generic Kilz or Zinser aren’t the best solution.
