I have a very lovable aging bulldog who has peed on the wall-to-wall carpet enough that I'm ripping it out. It's over twenty years old anyway.
The subfloor is a concrete slab. My goal is to make the concrete livable. Goals in order:
Urine-proof (waterproof). A puddle may sit for five hours before I get home to clean it up. Ideally a bit of soap and water, and no trace is left behind. None.
Low VOC products. I've got severe allergies to many/most chemicals. These rooms are my primary living space. I'll test whatever I plan to use, but I need to be very careful so as not to make the place uninhabitable for me. I'm disabled, and am in the main room probably twenty hours a day.
Easy application. Fewer products, fewer applications is better, though it's not the primary deciding factor.
Something attractive. Least important, but I'm thinking more mottled see-thru stain than I am glossy garage floor. Probably a medium brownish color.
The Home Depot employee giving me advice said I don't need to prime either product. Just apply to bare concrete. Said either product would satisfy the waterproof requirement.
However, the specs on the products contradict that guidance. Both say "primer required". The stain is "waterproof", the paint is not. Neither product is a "sealer". I'd have thought one of the goals was to seal the porous nature of the floor, at least a 1/2" down, no?
I am looking at priming with Seal-Krete Lock-Down Epoxy Bonding Floor Primer (sorry, I don't have enough reputation to post the link). A big plus for me is that it's the only product thus far with a Low VOC rating. If I understand it, this will seal the pores, and allow the paint/stain to bond properly. It's amber-clear, so it seems that would work under brown-tinted stain, even if the stain isn't completely opaque.
Does this sound like a good plan? Prime with the Seal-Krete, and follow with the Solid Stain?
Initially I wanted a transparent stain, to see the mottling of the concrete. But I had to prime. Since I'm probably priming anyway, would Behr Semi-Transparent Concrete Stain work? My concern is if the urine will puddle, or seep in? The product is not waterproof.
