Subject: Help (log home)
Date: Sat, 16 May 1998
Hi. We have a problem with our log home--dry rot has already started
destroying some of our logs. We have decided to side the house with steel
siding but we are concerned that the rot will keep on going through the logs
even though we have covered it. We are interested in doing something prior to
siding the house--which is scheduled to occur the first of June. Thanks for
any info you can give us. We sure do hope you have a product to solve our
problem. Thanks a lot. Eileen and Varron J., Pocatello, ID.
You are correct about the rot: It will continue to destroy the wood
underneath the steel siding.
What you do will depend on how much rot you have and how accessible it
is. Curing rot in log homes is not a quick process, usually, because you
have to get the Clear Penetrating Epoxy Sealer(CPES) into the rotted
areas, and the rotted wood should be reasonably dry. You find out what
you are dealing with by drilling test/access holes, determining how bad
the wood is by how quickly the drill sinks into the log and by looking
at what the drill pulls out. The larger the drill holes the better.
Having isolated the areas in which you have rot, you then have two
choices. 1) Flood the holes with the CPES, allow it to cure as long as
possible, and then close the holes with wood bungs. The CPES will
penetrate a long distance into the rotted wood, restore much if not all the structural strength of the wood, and make the CPES saturated wood highly rot resistant. 2) Cut away the face piece of the log and remove
the rotted wood, saturate the area with the CPES, fill the area with an epoxy/sawdust filler, and replace the face
piece (which was also saturated with the CPES).
It sounds to me that with a June steel siding coming up, that you are
more or less obligated to look at option #1. It's disadvantage is that
you can't see what's going on inside the log, but if the rot isn't too
extensive this may be okay. In any case, flooding the logs with the CPES
is a lot better than doing nothing and allowing the wood to continue to
rot. There would be some lingering odor for awhile until the carrier
solvents evaporate away. We had a family in Oregon use this method last
September, trying to stabilize the wood before the winter rains came in.
They just made it.
