Yes we most certainly can and they wear really well. Outdoor areas and driveways can be finished in a number of ways including CCC Acid Etch or with a matt penetrating sealer. A non slip finish can be added to some sealers.
Care should be taken however with a painted/sealed finish as most surfaces can become slippery when wet. CCC Acid Etch however solves the problem as the light grit of the finish provides great grip.
