This was my first experience sealing concrete. The product was easy to use. I dumped small portions into a smaller container and brushed it on with a 3" brush. I would have appreciated something in the directions that told me what proper first application would look likeso I could judge if I was applying it too heavily or thinly. Also, then, what a proper second application looked like. Even applying wet on wet ( I was doing a second coat well before half on the minimum drying time had passed) the second coat did not seem to sink in and looked milky, but dried fine. I appreciated the Armor customer help line. We have been in a long heat wave and they explained to me that the 85 degree max temp was important so the product didn't evaporate before it could penetrate during application. How it works for weathering is not something I can judge, but it does repel surface water.
