Recently applied to my front Driveway and walkways and my backyard patio. This is the first time I have sealed the front. Wish I had done it sooner as there were a few old stubborn stains I couldn't clean off. I used concrete wash, vinegar (which actually worked best) prior to a good pressure washing. Looks brand new now.
This is the second time I've sealed the back patio. The first time was about seven years ago when it was new. Both times I used AR350. I love the results and my neighbors love it too. Highly recommend this product, which I purchased with the non-slip sand, which works great too.
