concrete overlay big problem
We just had an overlay job done on our sidewalk, front porch, and back patio. We had a 18"x18" diamond pattern done. When the sealer was sprayed on the color of grout lines are now uneven on the sidewalk and front porch. The back patio is fine. The guy told us this has never happened before. Is there anything he can do other than taking it all off and redoing the overlay?
