Best Fast Cure Time Concrete Floor Sealer - Polyaspartic 85
When you need an industrial-grade coating that can be returned to service in the shortest amount of time, you want this product! The new zero VOC formula is designed to be easier to use for installers. This high solids coating has an extended cure time and still allows a quicker return to service than epoxy and urethane. Polyaspartic 85 is a great all-purpose final coat on many projects including garages, basements, commercial flooring and concrete countertops.
Why Use This Coating Over Others?
Fast cure/return to service time. Very thin, durable coating. It's easier to apply because it has a longer pot life (time to use it once mixed) and has zero VOCs (smell), can be applied VERY thin if you need to, and is a super durable coating. Polyaspartic85 can be used right over your plain old concrete once properly roughened/sanded to @ 100 grit, as well as stained concrete, and as a durable top coat to your cool epoxy/metallic epoxy floor. PolyAspartic 85 also excels as a top coating on quartz sand and flake broadcast epoxy coatings, as it will go on very thin over them, retaining some of that 'bumpy' texture from the broadcast.
This coating IS also good for outdoors, yes! Countertops, concrete furniture, tables, and even floors. It will be slippery when wet though, so use anti-slip in the sealer before applying if slipping is a concern.
If you have a few extra days to let your sealer coating cure, and need excellent chemical protection and a slightly thicker final build of the coating, please consider AU-85 (sold here)

I used it as a top coat for my garage floor epoxy project and it looks great! Did some research before doing the project and this product was highly recommended by some of the professional companies that do garage floors. The product was easy to use, but it dries VERY QUICK so consider making smaller batches. I noticed later some of the last areas I did with each batch were a bit wavey since it was drying as I was working with it but that was 100% my fault and inexperience. Just a warning, when they say short pot time, they mean it. Shipping was super quick! Expressions LTD Customer service was very responsive and professional too when I had a few questions in advance of using the product to ensure I used it correctly.
