Applied 2 coats of the Armor SX5000 WB High Solids Silane-Siloxane Penetrating Concrete Sealer to my new driveway and sidewalk using a 1 gallon sprayer. Went on easy, 5 gallons was perfect to cover my driveway and walkway. I like that this is DOT certified, so it can withstand the Michigan freeze/thaw cycle. New concrete is not cheap, and this is an inexpensive way to protect new concrete. I would recommend to anyone who is getting new concrete to use. Very happy with how it went on and how it works.
