What does everyone else find is the best way to de stink a plywood subfloor of dog pee? I usually use a bleach solution, but this house seems extreme. I felt like I needed a shower after just walking in the house all you could smell was dog piss.

We just did one we used oil =-based kilz brand primer sealer seemed to work fine, but anything was an improvement to this floor. Good luck

Forgot to mention that we scrubbed with bleach first

Use a hudson sprayer, and soak it with vinegar and water solution. Then just roll on the cheapest paint you can find. It dries non pourous, smell is gone. Just have to be aware of the wall locations , the drywall sucking it up, ( there's no face for nasty or gross ).

So feel vinegar works better then the bleach?

There's something about vinegar that neutralizes the urine, have used it a ton on cat and that's ten times worse than dog. Always painted over it though, seal it all in.

( You have to wait till the hottest day of summer to really enjoy the job )

Why not just demo it? Worst smell yet is cat urine on a door casing your undercutting.....RALPH

Ya , that's hard to handle. Replace casings, jambs, base, drywall. But demo the ply ??

I have an extra tough time with those type jobs, being allergic to cats. I feel funny wearing a mask , for what the customer might think ( how stupid ).

I,m going to price out replacing the plywood but she is already on a tight budget. If work wasn't so tight I would just pass on the whole job.

I hear ya, just figured a job for 250' of vinyl plank . Havent installed vinyl plank for over 20 some odd years!
