When it comes to expansion joints of new tile replacements, coping stones (new and old), broken deck joints, and plastic cracked ribbon above the tile we easily remedy this with our professional. Erma has been applying mastic and silicone to these areas since 1988.
Our mastic is a pourable self leveling joint sealant, a polysulfide-based sealing compound. It is a non-staining liquid sealant that cures to a firm, flexible, tear-resistant rubber. Once cured it is highly resilient and has excellent recovery characteristics, even after extended periods of compression or elongation. It has outstanding resistance to most chemicals, to all weather conditions, aging and shrinkage. Our applicator has literally sealed miles of expansion joints. The quality in her workmanship will show.
