First off, you need to remove the old adhesive completely from the slab. So long as it is not a black (cut back) adhesive it most likely has not asbestos in it, so you can first scrape and then sand the rest off.
I am not familar with dryloc like I am with Kilz. These type of products do a good job of sealing in such odors so long as there isn't any excessive moisture emitting from the slab itself.
There is much debate about the use of plastic sheeting under a carpet. The problem I have with it is trapping moisture between the concrete slab and plastic. If the concrete is not completely clean, mold can form in such a dark wet environment.
Typically when you install a standard carpet with a non rubber/vinyl backing (which also traps in moisture) moisture can vent through such carpets so long as the moisture emitting from the slab is not too much. I would suggest that you use a separate cushion not made from jute or horsehair (these can mold) and do a stretch-in installation. This way if you do have problems, you can pull back the carpet and deal with it.
The most important thing to do is to make sure you have rid the floor of all odor so any pets in the home do not pick up the scent indicating its ok to use this spot again.
Good luck, Evan
: I have two bedrooms with concrete floor and glued indoor/outdoor carpet and significant damage due to pet urine. The carpet has been removed and a chlorine/water solution applied to kill odor causing bacteria. However, I see the need to go ahead and seal the floor with a latex waterproofing sealer (I have purchased a product called Drylock)to seal the odors which may otherwise come back over time. I also need to remove the carpet adhesive before painting(with what I'm not sure). I need the paint to bond with the concrete and I understand that an adhesive remover may hinder this. Once I paint the concrete how should the new carpeting be laid, can it be glued or do I need to drill and anchor? I've read about a polyurethane vapor barrior which should be placed on top of the sealer. What is the purpose of this? Lastly, soon temperatures will not rise above 60 degree F during the day. Is this a concern with painting concrete? Any professional or experience based insights into my statements or questions above are greatly appreciated. Thank you in advance for you help.
