“Schöner Brunnen” Nuremberg

One of Nuremberg’s landmarks, the “Schöne Brunnen” fountain on the main market square in the city centre had lost some of its former splendour. In addition to the rust on the surrounding fencing, a large amount of cracks and paint scaling were detected, requiring a refurbishment of the entire structure. Due to the saturated fountain layers, renewed
waterproofing of surfaces and details needed to form part of the repair. A high-quality waterproofing material that was easy to process was required to ensure that the system would function for a long time. The Hochbauamt Nuremberg building construction authority, the executing company Märkl GmbH, Fürth, and the Minden-based liquid plastics manufacturer Triflex cooperated to master this challenge. Due to the Triflex BWS system that was used, the fountain is now able to withstand weather influences for a long time and can once again live up to its name.

Refurbishment requirements

  • Durable protection against moisture
  • Secure waterproofing of various details
  • Weather-resistant, robust surface
  • adhesion on shell limestone, sandstone and sheet metal
  • Refurbishment without structural changes
  • Unobtrusive refurbishment for historical monuments

Refurbishment steps overview

  1. Grinding the substrate and levelling any irregularities
  2. Priming the surface using Triflex Cryl Primer 287
  3. Sealing junctions and complicated constructions with Triflex ProDetail
  4. Sealing filigree and difficult to access areas with Triflex ProFibre
  5. Sealing the surface with fleece-reinforced Triflex ProTerra
  6. Finishing the surface with Triflex Cryl Finish 205

DESPITE THE CRAMPED SPACE CONDITIONS ON THE INDIVIDUAL WELL LEVELS, A LONG-TERM WATERPROOFING SYSTEM OVER A TOTAL AREA OF 150 M2 WAS CREATED. THE
COOPERATION OF THE PROJECT PARTICIPANTS RESULTED IN A SOLUTION THAT PERMANENTLY PROTECTS THIS NUREMBERG LANDMARK.
