Basic Hardener Bonding with Epoxy and 807 Syringes
For improved pullout strength and waterproof connections, the easiest method is to simply wet out the stripped fastener holes and new pilot holes before installing the screws. Epoxy penetrates the fiber around the hole, effectively increasing the fastener diameter. Epoxy also provides a stronger interface with the fastener threads than wood fiber and keeps out water.

  • Wet out a standard-size pilot hole. Work the epoxy mixture well into the hole with a pipe cleaner or 807 Syringe. Use a high-strength bonding filler to thicken a second coat of epoxy as necessary for stripped or oversized holes.
  • Insert the fastener in the hole and allow the epoxy to cure.

Bonding Hardware with Epoxy
By bonding the hardware base directly to the surface you further increase hardware load capacity and provide a solid bearing surface for the hardware. It also seals the wood underneath and is a stronger, longer-lasting attachment than bonding the fasteners only. It is especially useful to mount hardware on curved, uneven or un-level surfaces.

  • Prepare the mounting surface and the hardware base for good epoxy adhesion.
  • Wet out the oversized hole with epoxy using an 807 Syringe. Allow the epoxy to soak into the exposed end grain of the wood (as with fastener bonding).
  • Coat the bottom contact surface of the hardware with unthickened epoxy. Wire brush or sand the wet epoxy into the surface with 50-grit sandpaper.
  • Use an 807 Syringe to inject a non-sagging epoxy/404 High-Density mixture into the hole. Use enough epoxy mixture so there are no voids in the hole after inserting the fastener. Coat the bottom of the hardware and the fastener threads with thickened epoxy.
  • Place the hardware in position. Insert and tighten fasteners until a small amount of the epoxy mixture squeezes out of the joint.
  • Remove excess epoxy or shape into a fillet. Allow the epoxy to cure at least 24 hours before applying load to the hardware. Allow more cure time in cooler weather.
