Fiber cement mortar coating

FCM coating

Depending on the service conditions, pipes with a MAPEC® coating may require an additional coating of fiber cement mortar (FCM) for mechanical protection.

The FCM coating consists of dried quartz sand, cement and water, fibers, and other additives. Immediately before FCM coating, the corrosion protection coating is subjected to holiday detection at 25 kV. Then the mortar is applied via a slot nozzle to the rotating plastic-coated pipe. At the same time, an approximately 20 to 30 cm wide tear-resistant plastic fabric tape is wound around the pipe with an overlap. Subsequently, the FCM coating surface is smoothed down. During the coating process, the fabric tape serves to keep the mortar in place on the pipe surface. After hardening, it functions as a reinforcement.
