Product arrived FedEx well protected. It is very aqueous and covers a large area. I rolled it onto a well weathered concrete d'way that had been powerwashed and if sealed, it was a long time ago. It went on easy and soaked in. 5 gals covered about 1500 ft2. Dried to walk on in about 4 hours. Did not darken concrete. Rained a few days later, water beaded up in some spots. It was not slippery.
