  • Seal pest entry points in drywall

  • Patch holes after pest inspection or treatment

Application Instructions

For rodent prevention, stuff larger holes with steel wool or copper mesh first. Apply spackle with 1-inch spackling knife or putty knife. For larger holes: apply in layers, letting it dry between applications (typically 2-4 hours between layers). Do not apply too thick at once as it will crack. Sand smooth when fully dry (24 hours). Prime and paint over for finished appearance. Use setting-type joint compound for areas requiring extra strength.
