  • Pre-cut to fit standard sprinkler pipes
  • Repairs and reinforces mis-cut or damaged areas around sprinkler pipe holes
  • Install in areas where patching cutouts were made too large
  • Sprinkler pipe relocation



  • To apply, lightly sand area to be repaired.
  • Apply drywall compound 1/8”-1/4” thick directly to back of patch.
  • Place patch over center of repair and wipe down flat to wall using joint knife.
  • Immediately skim-coat patch and let dry.
