Zinsser BIN Primer vs Sealer for urine smell?

Hi all,

We pulled up our carpet the other day and immediately noticed a strong urine smell coming from the subfloor. We just recently purchased the house so this was undoubtedly caused by the previous owners large dogs.

We were told to hit the subfloor with a couple coats of Zinsser BIN primer. When I went to home depot, I found two options...

BIN Primer or BIN Sealer.

The sealer says that it is specifically for odor control, but the person who recommended this treatment said to use the primer which is for stain blocking.

Wondering if you all have any opinions? I think either would work, but i'd prefer to get the primer so I could use it for other priming applications as well.

I've never used the BIN sealer. According to Zinnser's website it's a synthetic version of the original pigmented shellac BIN. I'd be inclined to use the BIN primer as I know it works both for sealing stains and odors. Normally one coat is enough but it does need to be a full fluid coat [no thin or missed spots]

Both are probably fine but, just like Mark, I'd pick the primer since that's where my familiarity is.

I have used the BIN primer for such occasions. When you own rental property it's a sure bet someone will sneak a dog or cat in there. LOL
Cat urine is by far the worst to cover. Wash the floor with an ammonia and water solution first, making sure the room is well ventilated. Rinse as best as you can, let it dry fully before trying to seal it. 2 coats should put you back in business. When painting with BIN, make sure the room is really well ventilated. Along with the shellac it also contains ammonia. The smell is really strong and can knock you right on your butt. I know, I forgot to open the windows one time and it hit me like a stone. Keep the bottle of ammonia handy for when you got to clean your brush, it does a great job.

You should never clean urine with ammonia - it will leave behind a scent which makes future pets more likely to use the same spot.
