The magnesite screed was removed with a road milling machine and the substrate was prepared with subsequent shot blasting. The surface was then primed with AB-POX® 001 and completely sanded. In order to be able to install the surface in 2 sections, a joint was cut through the length of the hall and set aside. The floor leveling compound was installed using a Mobileman D5 pump truck. The leveling compound was mixed in the truck’s mixing unit using VELOSIT SC 253 binder and washed 0-2 mm sand. VELOSIT SC 253 can be used to produce levelling floors from 3 – 50 mm with a grading curve optimized for the respective layer thickness. In the first section, 27 tons were pumped and placed within 3 hours. After the truck had reloaded, the second section was pumped. At this point, the first section could already be walked on. A total of 55 tons of levelling compound could be installed in one day. The pumping rate had to be reduced to approx. 8 tons per hour, as otherwise the paving crew would not have been able to keep up. On the following day, the compressive strength was already approx. 43 N/mm2 and the determined adhesive tensile values were also over 2 N/mm2. The surface was therefore ready for coating and was shot-blasted again the following day. The coating was then applied using the AB-POX® 460 ESD system from AB-Polymerchemie GmbH, which has been tried and tested in accordance with standards since 2002, and was installed to the client’s complete satisfaction.
