Here, McCahill Painting Company cleans a dirty and discolored acoustical tile and grid ceiling, restoring it to its original condition. After vacuuming and hand washing the tile to remove dirt, dust and other contaminants, we carefully mask all substrates not related to the ceiling. We then spray-apply a specialized cleaning chemical that rejuvenates both the acoustical tiles and the grid system. The ceiling looks like new, and the tiles retain their acoustical value and fire rating.
