Subject: Question (Beam In Wood House)
Date: Fri, 20 Mar 1998
I have a structural beam in a wood house (in suburban Portland, OR) that is
exposed to weather for a section of its length. The beam appears to be a
custom dimension, approximately 12" wide X 24" deep. In the portion that
is exposed to weather, there are several deep fissures of dry (or wet?)
rot. They are parallel to the grain, penetrate perhaps half the depth of
the beam, and are an inch or so wide.
Is your product appropriate to fix this condition?
Does it restore the lost strength in the beam (e.g., where epoxy cement is
used in cracked concrete, the bond is actually stronger than the original
Does it stop the process of rot from re-occurring?
Any other thoughts or comments?
VTY, Hugh C.
Like epoxy cement, our products restore strength to wood that makes the
repair stronger than the surrounding wood. It does greatly restrict the ability of the rot to continue, since the Clear Penetrating Epoxy Sealer (CPES) penetrates as
far or further than the rot fungi. They are encapsulated at this point.
What you would need to do is 1) clear out any loose bad wood you can get
at; 2) get the area to be treated as dry as possible (we've used
everything from hair dryers to commercial kerosene 80,000 btu blowers if
the wood is not naturally dried out); 3) soak it with the CPES (giving
it all it will absorb); 4) going back after the CPES has cured (3-4
days) and filling with either or both the Layup & Laminating Resin
and/or the Fill-It Epoxy Putty. The putty is fine alone if you have a
clear shot at the bad area and can force the putty down into the rotted
area. The L&L Resin has the advantage of remaining liquid and being able
to settle for greater penetration. Kind of depends on what you are
looking at. Both the resin and the putty bond at the molecular level
with the CPES -- very strong!
Additionally, I would coat the exterior of the beam (as much as you can
get at) with the CPES, which will protect it from future rot incursions.
How much material you would need depends of course on how much of the
beam is rotted. Kind of a decision you'll have to make. In any case,
Portland is close so UPS should get there in 2 days.
All products are in stock and will ship same day ordered if order in
before noon. If you have additional questions, please ask.
