Application Situation
The shaft was on an air handling equipment that was used primarily to circulate the air through the common hallways. The equipment was in the lower level of the building.
Application Method
The application was carried out in accordance with Belzona Know-How System Leaflet MPT-2 for rebuilding damaged shafts using forming techniques. The area was prepared for application using a grinder to roughen the surface. Belzona 9411 was applied to the former in accordance with appropriate Belzona Instructions For Use. Belzona 1212 was applied onto the shaft and former, then the former was attached to the shaft, allowing Belzona 1212 to cure. Once Belzona 1212 cured, the former was removed and the application was completed by removing trim lines and excess material.
Belzona Facts
Belzona 1212 is a paste grade multi-purpose epoxy based material that utilizes the latest technology to achieve rapid cure and excellent adhesion to poorly prepared substrates. When fully cured, this two-part system exhibits outstanding mechanical strength. Repairing shafts using the forming technique provides a smoother finish than machining and, more importantly, can avoid the need to dismantle and remove the equipment from its location.
