I did a half hour of painting and melted down with my ankles swelling and my breathing becoming labored. I spent the day in bed since 10 am. I will probably stop and get some antibiotics in the morning, but I have business most of Monday, Tuesday, and Wed, and will do little at the house. The vinegar was amazing with the peroxide and dawn dishwashing soap. The smells are not being reduced and if they are not by Wed., we will be cutting out the really bad spot in one bedroom and just be done with it. We will apply Kilz on all the subfloor on Monday night after one more treatment, but we think a four by four area is the only subfloor to be replaced and it would take care of 90% of the urine spots, and we both could knock that out in an hour, but we have to make sure we have a match with thickness exactly, and I bought some treated 2 x 4s to frame the area we took out. We have our tools and this drastic step is the ONLY way to guarantee that the smells will be gone. We will still seal the entire floor, but the worse section has to go.
