1100 sqm of epoxy resin coating removed in just three days
Successful renovation of the industrial floor of a logistics centre during ongoing operations procedure
tags: ApplicationsRenovationPrepare the subsurface share:The end result was the perfect substrate preparation for the application of a new coating. During our work, operations continued as normal in the hall of a logistics centre.
"It was a challenge to remove the coating from a cracked industrial floor on 1100 square metres during ongoing operations," says Ralf Wetzig from the application technology department at Schwamborn, the construction machinery manufacturer in Wangen. The application technicians support Schwamborn cus-tomers with advice, action, expertise and in this case also with a rental machine. "It was clear to us that we could not meet our customer's requirements alone. In order to remove the covering in such a short time without disturbing ongoing operations more than necessary, we were dependent on support," says Björn Weber, owner of Weber Industriefußboden GmbH from Coswig. "We were therefore very happy that Schwamborn Gerätebau, our preferred manufacturer for grinding machines, were able to help us quickly and competently."

"180 sqm per day with perfect results is an outstanding area performance," adds the flooring expert. To achieve this, two Schwamborn DSM 800RC floor grinding machines with remote control were used, working in parallel, enabling successful decoating in a single grinding pass. Schwamborn "Barracuda SC-Splitt" dia-mond tools with a hard bond were used to remove the epoxy resin coating, while EX - Stripp soft from Schwamborn's ETX1 Premium diamond tool line was used for the polyurethane coating. Entirely in line with the basic rule of Schwamborn's application technology: using soft bonds for hard floors and hard bonds for soft floors. "Choosing the right tool," says Ralf Wetzig, "is a science in itself. But it makes great sense for perfect results and area performance to seek advice from us again if in doubt. In this example, the configu-ration of machine and tool was ideal for both coatings to be removed."


As this impressive practical example shows, the large-scale removal of floor coatings and substrate prepara-tion has evolved massively, so that in future interruptions to operations during ongoing floor renovation can be avoided.
