I bought three 5 gallon cans of AR 350 and applied with a roller on a 300 sf previously sealed concrete driveway + walkway. Two 5 gallons were completely used with one coat application. It went on well and the smell went away after some time. It looks very nice and I am happy with the purchase.

Will recoat the surface in a couple of years.

I did return the coarse non-skid powder back as it was too rough and could not be mixed with AR350 while applying with one coat. I used Sherwin-Williams non-skid powder that easily mixed with the sealer. This worked well.
