Polyaspartic garage floor coating concern

[youloze]

Hi all, I am having a house built with a 4 car garage (will be finished around August). I used the Armorpoxy Polyurea product on my previous garage floor and while it performed well - I'm not easy at all on my floors - it had terrible "hot tire pickup" so I had unsightly yellow spots where all cars were parked.

I want to avoid that this time around and from what I've read it seems a 100% solids Polyaspartic product would be best for me. One thing that I've read, however, has me concerned. It seems that due to the fast cure time and the thinness of the product, it may tend to lift due to not having enough time to adhere to the concrete.

I also read there may be a way around this in such that you lay down an epoxy base, then add the Polyaspartic top coat. Would this be the ecommended route for my particular situation?

Also, keep in mind that this will be a new concrete floor that has never had anything done to it and was poured in February. Would I need to do anything more than a simple acid etch and power wash to prep?

Thanks everone!
Mike

Polyurethanes are better against hot tire pickup then polyaspartics. Depending on what you’re looking for, an epoxy primer and polyurethane topcoat is a great option if you want a colored floor. Several of the vendors in the forum sell kits designed for DIY applications (include etc, tools, products, etc)

Thanks Andy, but don't Polyurethanes have issues with yellowing from UV?

Based on my research it seems that the polyaspartic does not yellow from UV nor will it cause the yellowing under hot tires. I'm just concerned of it not adhering well due to the fast cure time.

Would it be advisable to use an epoxy base with a polyaspartic top coat?

As long as the polyurethane is pigmented then it's UV stable. If It's clear, it can yellow the epoxy underneath but that's the same thing for polyaspartics. Full flake floors are another great option to avoid yellowing. My suggestion is epoxy with polyurethane or polyaspartic topcoat but it needs to be pigmented topcoat or a flake floor system, if either of those are what you want.

Thank you. I am just looking for a simple gray like my last floor - no flake, as I work on cars a lot and it's a nightmare to find dropped washers, nuts etc on a flaked floor.

Sounds like my best option is an epoxy base coat topped with a pigmented polyaspartic then.
