Fixing Decayed (Rotted) Wood Using an Epoxy Penetrant and
When you come across rotted wood in your old house projects,
instead of replacing the damaged wood, you also can repair it
with specialty epoxy penetrants (also called consolidants) and
fillers to make repairs. Not only is this faster, but the fixed
wood is stronger than the original. For example, if you are fixing
an old window and you strip the wood, paint on an epoxy penetrant.
This will not only strengthen the wood, but also give it complete
protection from moisture for decades once it is primed and painted.

Here are two examples of how we used an epoxy penetrant and
filler to fix damaged wood.

|After we removed the paint from our siding,
we came across some boards that had decayed. One end was
soft enough to push a pencil through. Instead of removing
the 16' siding, we decided to rebuild the bad end using an
epoxy consolidant to harden the soft wood.
We drilled a series of holes one inch apart and half way
though the wood. We then mixed the epoxy and painted it over
the bad parts of the wood. We also used a syringe to inject
the consolidant into the holes.

flashing has been pasted behind the board.

|After the consolidant hardened, we used epoxy filler to
reshape the missing parts of the siding. We didn't worry
about creating an exact straight edge as the siding is old.

filler wouldn't bond to the board behind it.
