Plan to buy twice as muchThis concrete caulk seems to adhere well. There are two issues to be aware of when using. 1. Unlike ANY other caulk I've used, this caulk will continue to run out of the tube no matter what you do to try and stop it. I went so far as to remove the tube from the gun to eliminate any pressure; it still oozed out while smoothing the previous bead. Have plenty of paper towels or rags handy. 2. The label states it will cover 56 linear feet of a 3/16" bead. If you are filling 1/8" expansion-joint saw cuts, figure about 24' due to the material squeezing down into the joint. You are actually creating a 1/8" x 1/4" (or more) bead rather than a uniform, circular bead. Time will tell how long it lasts. My concrete driveway sealing project has begun 1 year after it was poured (September, 2015). Caulk the joints, then seal with a penetrating siloxane based sealer.
