Fasco Stop-Rot – Epoxy Penetrating Sealer

Fasco Stop-Rot is a professional-grade epoxy sealer designed to halt and prevent wood rot. Its thin, penetrating formula soaks deep into soft or damaged wood fibers, hardening as it cures to stabilize and restore strength. Stop-Rot creates a moisture barrier that protects against future water damage and provides a strong foundation for coatings and laminates.

Key Features

• Low-viscosity epoxy resin designed for deep penetration
• Reinforces and hardens rotted or water-damaged wood
• Seals porous surfaces to block future moisture intrusion
• Improves adhesion for fiberglass, paints, primers, and fairing compounds
• Easy to apply with a brush, roller, or by injection

Recommended Uses

• Repairing soft decks, stringers, and transoms
• Stabilizing plywood, hardwoods, and dimensional lumber
• Preparing wood before fiberglass layup or painting
• Marine, residential, and industrial wood restoration projects

Application

Apply Fasco Stop-Rot to clean, dry wood. For deep penetration, multiple wet-on-wet coats may be applied until the surface is fully saturated. Allow curing before applying epoxy laminates, gelcoat, or marine paints.

Pro Tips

For large structural repairs, combine Stop-Rot with Coosa Board or Divinycell foam for long-term reinforcement. For filling after sealing, use Fasco Fair 26 fairing compound.
