TECO or Tampa Electric has not pressured washed their sidewalks and roof tiles in years. Mason Global LLC approached them about using SelfClean and Shield after their next scheduled pressure washing. In August, TECO pressured washed then a couple of days later applied SelfClean on their sidewalks and Shield on their guard house roof tile. SelfClean and Shield, a cutting edge masonry treatment broke down the remaining mold and mildew to restore the sidewalks and roof tile to better looking surfaces. SelfClean and Shield will continue to prevent organic staining for years, thus eliminating having to pressure wash for many years to come.
