Restorative Techniques products were chosen to clean the University Leisure Centre and Restaurant, Limerick, Ireland.

A key factor in deciding which cleaning approach to use was that the centre is open seven days a week and has a constant stream of visitors.

Overall, the rendered substrate was in very good condition. Localised areas of dirt had built up in the splash zones alongside pathways and under some of the more open joints in the coping stones along some walls. Because of the nature and use of the building, algaecides and other cleaning chemicals were prohibited and attention needed to be paid to the segregation of work and public areas.

Chemicals could not be used, so ThermaTech Superheated Water Cleaning System was the clear choise. For the most part, the desired results were achieved in a single pass with the ThermaTech operating at 140ᵒC and 80 Bar pump pressure, allowing us to treat the elevations quickly and efficiently. The areas of deeper, more stubborn staining required a second pass to lighten them to an acceptable level, but yielded very well after the substrate had cooled and dried from the first pass.

ThermaTech system removed the majority of the dirt very easily and to the satisfaction of all parties.
