Two Part Epoxy for Wood Repair
Epoxy wood filler is a type of putty mixed with glue that provides a strong bond between wood and the putty. The putty is designed to replace chips and cracks in damaged wood. Epoxy is a common repair for rotted wood because it resists mildew and moisture. Applying two-part epoxy repair to any surface is simple and requires few tools. Wood can easily be restored to full strength within 24 hours. Does this Spark an idea?

Preparation
-
Preparation for using an epoxy as a repair for wood is simple. Determine what caused the wood to rot in the first place. A wood repair on wood that will continue to rot is pointless. Generally, wood rot is caused by too much moisture due to rain or leaks. Stop any leaks; there is not much you can do about the rain. Chip away the old, rotted wood using a chisel. Solid wood will feel hard against the chisel. If the entire wood piece is rotted, replace it. Epoxy only works on smaller areas of rot.
Application
-
The first step in applying the epoxy to the wood is to use a borate wood preservative. Place the borate in a squirt bottle. Drill several small holes (1/4 inch deep) into the wood and squirt the borate into the holes. Next apply an epoxy primer over the surface of the wood. Use a small paint brush to brush the primer over the wood. Allow to dry. Make sure that you have an epoxy wood filler--there are two-part epoxy glues that are not suited for wood repair. The epoxy will state on the package if it is used for wood repairs. Mix the two parts of the epoxy together (one is the resin and the other is the hardener) on a piece of cardboard or other flat surface. Apply the epoxy over the wood with a putty knife. While wearing chemical-resistant gloves, shape the epoxy to the original shape of the wood. Allow to dry for 24 hours.

Finishing
-
When the epoxy has dried, use sandpaper to smooth down the edges so the surface of the epoxy becomes seamless with the rest of the wood. You can also use a rasp to file down large areas or to access places where the sandpaper cannot reach. Follow the sanding with a coat of primer paint, and after that has dried, several coats of paint.
