Odor from subfloor

by Pmp29260367
We removed the carpet in our house. We thought it was causing a strong sour smell in the house we are renovating. Smell is better but not gone. Subfloor has spit were it looks like the other owners may have had a dog. How can I remove the odor from the subfloor.

    your going to have to neutralise the area soda, vinegar wash the area. Here's how.

    Using baking soda and water, combine the two ingredients into a small bowl to make a paste.

    Apply the paste to the affected area. ...

    Next, pour enough distilled white vinegar over the area to cover the stain.

    rinse and repeat...


    Paint the entire floor with a heavy coat of Kilz oil based(latex doesn't work as well. ) Maybe even two coats.Use a roller with a thick nap. (Plywood is difficult to get into the cracks)Then a heavy sheet of plastic over the entire floor. You are ready to put down new flooring over the top.

    To get rid of pet urine you need a pet enzyme cleaner. I like the tablets myself cause they are twice as strong and why pay for water?

    You may want to order the black light flashlight too as urine floresces lime green, fido may have lifted his leg on the walls too.

    I once moved into a home that had a ton of dogs and cats from prior tenant. It smelled so bad in there from all the urine I couldn't stand it. I pulled up all the carpet and soaked the plywood down with Natures Miracle via a garden sprayer for several days and finally all odor was gone. I'm a firm believer in that product , available on pet store but a lot cheaper on Amazon. Good luck

    I think you can seal the sub floor with a product like Binz.
