Chinking FAQ
Can I stain before chinking? When applying Perma-Chink or Log Jam Chinking and using a water based stain, the chinking may be applied before of after staining. If using oil-based log finishes like NatureColor Base or Recoater, WeatherSeal, Woodguard, or WR-5:
  • Apply chinking over one coat, and then apply a second coat of log finish the following year.
  • Before chinking, wait at least 21 days after staining to allow for cure time. Outlast Q8 Log Oil can be chinked with a urethane caulking after 30 days. If using a water based chinking wait 60 days in warm weather (Summer) and 90 days if cooler or Spring/Fall. Paraffinic oils like in X-100 can cause adhesion failures.
