Rot Fix is an easy to use low viscosity epoxy wood sealer, primer and consolidate for repair and restoration of rotted, deteriorated, dried out or spongy wood. Rot Fix is a component of the End Rot system. It creates a sound, waterproof base for repair and restoration filler putty. It penetrates deep into deteriorated and rotted wood creating a strong, solid base for restoration.

  • Premium Epoxy: RotFix is an ultra-low viscosity, solvent-free, low-odor wood epoxy that penetrates deeply into soft, punky wood substrates
  • Easy To Apply: Brush our penetrating epoxy over the repair area; Some wood substrates are highly porous and will absorb the RotFix rapidly
  • Versatile Application: Our epoxy resin hardens punky wood, and it can also be used as a stand-alone wood consolidant product for firming up punky wood prior to primer or paint application
  • Curing: At 70F our wood repair epoxy can be sanded with 150 grit sandpaper in 24 hours; Make sure that RotFix is completely deglossed before applying primer
  • Tips and Tricks: RotFix epoxy wood sealer does not kill rot fungus or keep it from returning; For long-term protection from rot and decay, first use EndRot Borate Powder
