ABSOLUTELY! All cracks are repaired using high strength epoxies prior to applying the skim coat. New tension control joints are then cut, or existing ones cut deeper, to alleviate the tension and allow for the movement that initially created the crack. (Note: Due to the multitude of parameters that can cause cracks, cracks cannot be guaranteed against re-cracking; however, cracks that return are often barely noticeable, and if necessary repairs are virtually undetectable.)
