Hey everyone, i have a driveway cleaning and sealing coming up soon. There is one spot by the front porch at first glance i thought was just scum, dirt, and just built up crude. Upon closer inspection it is hard scale i would call it. Not sure if it is old driveway sealer that has been built up and broke down too much over the years or what? I tried a test spot to see if it would come off with just heat and pressure with no effect at all. Any help on how to approach this would be great?!?!
Drive way possible old sealer failure?!?!?!
