It's getting to that time of the year again and cracks in concrete and joints may need attention, I came upon this product years ago and it has saved me with expensive joint sealing or just random cracks at the wash and at home, all you need is to clean out the crack or joint put in backer rod (if needed) then insert the crack stix and melt with either a torch or weed burner I strongly recommend the black crack stix as the gray crack stix tends to burn easy if you focus the heat on it too much and then it looks discolored, check out the link below.
