Polyurea basement and garage plan

[sford679]

I was making plans to do a coating on a 40x30 pole barn and after researching came across the idea of polyurea. I like this for the UV protection. After I bit I realized I should maybe use it to reseal the basement as well to remove that old house smell.

My question is..is this a good idea? Do I do just the floor or the walls to? What do I need to do to prep with this? Can I paint it over the steel tensioner things along the wall?

I don't know what that is on the left whether just paint or some sealer but how do I remove it? Do I need to check if everything is sealed and acid etch if not? If that is paint on the wall do I need to get that off? There is nothing on the oppsite wall so what all do I need to do to get this proper prepped is the question?

Also would like to know if I could mix colors together to make more. Like if I had 5g of gray and a leftover 1.5g of white, could I mix them to get 6.5g of lighter grey?

1st do some moisture testing. Once complete, 100% solids epoxy would be good for a basement, low smell and UV is typically not an issue. We have such a kit here: https://www.legacyindustrial.co/products/sd-epoxy-garage-kit/

The walls can be epoxied as well (and anything else on the wall), just make sure paint is dust free, here is product for that: https://www.legacyindustrial.co/products/gyp-coat-wall-coating/

Yes, you can etch the basement floor, product here (salt etch): https://www.legacyindustrial.co/products/hd357-concrete-etch/

Good luck with your project.

You might want to get some opinions on this, but if it's anything like the polyurea floor coating I used it will definitely change the sell of your house. I'd read a lot of stories about how terrible it is for weeks or months so I wasn't too surprised. Actually I kind of liked the smell in my garage, but not in a house. It was a strong chemical smell for at least 6 months. I think it was actually a lot longer but I got used to it and only noticed for a few minutes after walking in.

OP: I would not suggest using polypropylene in a basement. I would use a much higher solids product.

BSWS: Issues with odors beyond a week on Polyurea are the exception as opposed to the rule. The odor is crazy strong at first, but the solvent dissipates very quickly.

What is polypropolene? Same as polyurea? So you're also saying that I should get a 100% solids epoxy? I was wanting polyurea because of the UV resistance since there are a lot of window wells and I am also planning to build a walkout with a glass door eventually. I don't really want a bunch of window shaped yellow spots on the floor down the line, but I guess maybe the sun exposure still wouldn't be enough to cause that.

Would a polycuramine do me good?

Sorry typo. I had just answered someone about tiles.

I hear you on the UV resistance. I know our products are very UV resistant but over time, epoxy is considerably more susceptible to UV than urethanes. That said even an epoxy with a tinted UV top coat would have substantially less odor than Polyurea

Would it be best to hit the rest of the rest of the unpainted concrete with a kilz primer and then apply the gyp-wall coating? So I could get it down to one coat? And will can it be applied over this whatever it is?
