1) First, clean out the expansion joint. Make sure it is free of debris, dust, and any other chemical or material that could prevent the repair material from properly adhering.

2) Fill the entire expansion joints, up to the surface and over the damaged areas, with the FS-90 Crack Repair Kit.

3) Allow it to cure completely, about an hour, then re-cut your expansion joints – make them about ¾” deep.
