Re: sealing product for studs
Deb!!!! Long time no see. Whatcha been up to?
YES! YES! YES! For God's sake YES!
First, tell Auntie to get over her fear of primer, she's gonna need some in this case. Before priming, there are two products that do a decent job of urine odor removal, my preference is Natures Miracle, the second is Urine Off. Both use enzymatic action to neutralize the urine. I'd saturate the studs AND the floor with whichever product you choose. Let all dry thoroughly, then coat the studs AND the concrete floor with pigmented shellac (Zinnser red label primer ).
Be thankful that it's dog urine and not cat. You want to talk about some nasty odor, fricken felines are at the top of the nasty scale. I had to rehab a "cat" house. As the story goes, the previous owner had upwards of 40 cats and no litter box. The stench in the house was so bad you literally could not breathe, even with a vapor mask it was tough going. We pressure washed the concrete floor, bleached it, applied Natures Miracle, sealed floor, walls, and ceiling with pigmented shellac, and it still stunk. The odor really didn't abate until the new vinyl was laid in the kitchen and bath and then before the carpet went down we sprinkled a heavy dose of baking soda. After ALL of that, the odor was reduced to a mild "musty" smell. We also washed and painted the exterior and washed down all the surrounding concrete, which helped the entire property not stink like vile,dirty, rotten cats!
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
