We bought this 5 gallon container of SX-5000 sealer for our huge flagstone backyard. We've used others before and wanted to try something better. This came on the day it was promised and we got busy.. We have about 1100 sq.ft to cover. We used paint rollers and it went on easily.. dried pretty fast and looks great. Don't know yet how long it will last, but so far I'm happy with it. Doesnt' smell, easy clean up too.
