The University of Kansas Allen Fieldhouse has hosted many legendary games in it’s long history. Age and exposure to the elements had caused a number of issues to it’s limestone and brick exterior. The eastern part of Kansas has a wet and cold climate. This contributed to a build up of mold and pollution on the building’s exterior.
The old building was in need of renovation. The Ward family of Kansas City pledged more than $7 million to help with the rehab. The total scope of work involved new windows, lights, a new court, stair towers, fire alarms, sprinklers, and electrical systems in addition to the exterior work.
Western Specialty Contractors' Kansas City Branch received a contract to handle the exterior work. Working from swing stages, the Western crew applied a Prosoco’s Enviro Klean® BioKlean™ solution, allowed it to dwell on the surface for twenty minutes, and then rinsed it off with high-pressure water. A neutralizing agent was then applied. This mildly acidic afterwash not only neutralized the cleaner, but it helped to brighten the limestone.
To help keep the buildng clean, Western treated the exterior with Prosoco Sure Klean® Weather Seal H40, a masonry-strengthening water repellent. The penetrating breathable treatment keeps water out of the stone without changing it’s appearance.
