Easy to use, no odor. I followed the manufacturer's instructions to apply the sealant on my 2.5 yrs old concrete driveway that has not been sealed by builder. 5-gallon container is good for a 2-car driveway with 2 coats applications.
We applied the sealer around 2pm sunny with a slight breeze, the coating dried slowly to completely dry within 4 hours. We unfortunately had a light midst on the next morning but so far, the sealer seems to do its intended function.
