In this photo you can see it's a commercial application so it most likely will not be sealed over. However, on residential applications it is not necessary to go over the product with a driveway sealer unless it is greater than in 1/8th below the surface. If the Crack-Stix is level with the asphalt surface, for best results I would recommend lightly re-heating the Crack-Stix and broadcasting sand over the surface of the repair. This will give the Crack-Stix a rough texture allowing the sealer to grab onto the product better and last longer!
