You can coat your curbs whether they are concrete or block. Just allow a little more material when doing block curbs since they absorb more material. To apply the flakes to them you can toss fingerful amounts of flakes underhanded onto the curbs. Some customers have told us that they spread some flakes on the floor alongside the curbs and puff them up onto the curb with a leaf blower. You can also do wood molding and steps in your garage, we would recommend priming with our Bonding Primer first.
