Holes can typically be repaired by installing a patch of KERDI or Schluter®-KERDI-BAND with Schluter SET®, ALL-SET®, FAST-SET®, or unmodified thin-set mortar, making sure to provide a 2" overlap in all directions. Small penetrations on walls may also be repaired using the Schluter®-KERDI-FIX sealant.
To maintain the Schluter waterproofing warranty, special care must be taken to maintain a 2" KERDI/KERDI-BAND overlap.
