Very happy with this product! I applied it just over a year and a half ago and I have noticed a big reduction in how much mold grows on the shady part of my driveway. Even when some starts to appear, it is really easy to clean off with the hose. My driveway looks a lot cleaner and is much easier to maintain. Even though the beading has started to go away, it is noticeable that the sealer is still doing it's job! I just got another pail for my back patio. Thank you again!
