Effect of Grinding on Durability| Concrete Construction
If the grinding goes deep and exposes large areas of the coarse aggregate it may affect the durability. If this describes your driveway you may wish to treat it with linseed oil to improve the durability. Dilute the first coat with an equal amount of mineral spirits and mop it on but don't leave puddles. Dilute the second coat somewhat less.
