1. determine the extent of the decay by probing with an awl, ice pick or by drilling 3/16" holes.
2. Chisel out all of the decayed wood exposing sound bare wood.
3. Determine the amount of migrating borate preservative (such as BoraCare) to apply, based on the volume of the piece of wood and the application rate for the preservative (1 fluid ounce per 6 board feet for BoraCare).
4. Drill hole(s) in the bottom of the decay void.
5. Mix and apply the borate preservative into the holes. Be careful to not get any borate on the surface of the wood.
6. Fill the hole(s) with a wood plug.
7. Apply the epoxy primer or consolidant to the surface of the decay void.
8. Apply the epoxy paste filler to fill the decay void. Slightly over fill above the surrounding wood surface. Allow to cure.
9. Trim down the epoxy filler to be flush with the surround wood surface.
Tools:
Application Bottles
Narrows-spouted hair dye bottles work well because they have a good seal at the cap. If they are made out of poly-ethylene plastic the cured epoxy will not stick to them making them cleanable.
Ordinary "ketchup bottle" are not good because the seal is not good enough and they are sometimes made out of other plastics so they may not be cleanable.

Cleaning Epoxy Application Bottles
This type of bottle is made of poly-ethylene plastic so the epoxy materials do not stick to it after they have cured.
This cleaning method works with the Abatron consolidation product LiquidWood and Roux or Revlon hair dye color application bottles. Other bottles and epoxy products may work slightly differently.

The bottles you see in my videos are hair dye bottles made of poly-ethylene with an effective seal around the cap and a very narrow spout. They were available since the 1990s through Sally Beauty Supply (a chain of stores all across the USA) with the "Roux" and "Revlon" brand names, but those specific products have been canceled and are no longer available.

I use three or four different brands, each has different characteristics that might be needed for a specific wood-epoxy repair. Brands include: ConServ, PCWoody, West System, Abatron, etc.
For a complete rundown on all of these, get the Wood-Epoxy Repairs booklet:
http://historichomeworks.com/publications/#epoxy
For those just starting out with wood-epoxy repairs I often recommend Abatron's products LiquidWood and WoodEpox. When they do not meet your needs then try the others. _________________ John
