Where to use PeneTreat
Use PeneTreat on above-ground wood surfaces,
including logs, timbers, dimensional lumber,
siding, etc. Wood subject to direct moisture contact
must be coated with a good water-repellent
finish after treating with PeneTreat. If using Log
Keeper™, be sure to apply PeneTreat first.
Wood must be bare; free of dirt, wax and surface
finishes. Remove all previous coatings by
cob blasting, sanding, chemical stripping, sandblasting
and/or high-pressure water. Surface
discoloration from mold or mildew should be
treated with CPR Log Cleaner &
Brightener before applying PeneTreat.
Do not apply to frozen wood. Log (not air)
temperature must be between 40°F and 90°F. It
is best to apply PeneTreat to dry wood.
Mix at the rate of one pound, or loosely packed quart, to one
gallon of water. The PeneTreat mixture requires only mild
stirring before application. The mixture will be clear and
With this mixture, all application methods described below
will yield a minimum retention level of 0.24 pounds per cubic
foot boric acid equivalent to 1/2”.
Methods of Application
PeneTreat may be applied by:
Full immersion dipping yields the
deepest and most complete protection, especially with large
Kerf-flooding accompanied with brushing or spraying,
yields nearly the same level of protection as dipping.
and spraying can completely penetrate dimensional lumber and
can provide excellent “shell” protection for timbers and logs to
a depth of 1/8”-1/2” — which is adequate for most applications.
NOTE: Diffusion of PeneTreat into the wood begins immediately
and requires several days for completion.
protection in large logs or timber, all pre-existing insect larva
may not be killed. Upon maturing they may emerge from the
wood. Insects must ingest the substance to be killed—PeneTreat
is not a contact killer. Further insect infestations, however will
Brushing or Spraying Penetreat Apply PeneTreat at a rate of 1 mixed
gallon per 150 ft2 of wood surface.
Apply a second coat 4-24 hours later.
Thoroughly soak cut ends and apply to
checks and cracks.
Logs 9” in diameter and larger are
often kerfed to control unwanted checking.
When kerfing a log
in the shape of a trough (with 3/8” wide chain saw to a depth of
3”), just pour the PeneTreat solution into the kerf.
Fill the kerf
at a rate of 15-20 lineal feet per mixed gallon.
Let soak. It will
take 1-2 days for the logs to absorb all the liquid.
Protection may also be gained by pouring
powdered PeneTreat into the kerf (0.2 to 0.3
pounds per lineal foot).
Pour water into the
kerf to dissolve and carry the PeneTreat
into the wood.
Brush or spray the exterior of the logs after
either of these methods as described above.
Hole-flooding is similar to kerf-flooding.
NOTE: Be sure the kerf or holes do not affect the structural
strength of the log.
Dip logs or lumber in PeneTreat for 6-10 minutes, depending
on log diameter.
Let excess liquid drain back into the tank, dip
again 24 hours later.
Cover wood with a tarp or place in a shed
for at least 48 hours prior to coating with a good exterior finish.
Use of an anti-sap stain biocide is recommended in conjunction
HINT: Runoff from vertical walls may be contained by using
plastic sheeting to form an accumulation basin. The trapped
liquid may then be recycled and will be prevented from injuring nearby foliage.
After Applying PeneTreat Borate Wood Preservative
Treated wood must be protected from direct contact with moisture
or the active ingredient may leach out.
It’s best to wait at
least 48 hours (in warm weather, longer in cool weather) after
applying PeneTreat to coat wood with a water-repellent finish.
Let the surface thoroughly dry and brush away any crystals
that appear before staining. Use a moisture meter to verify that
the logs’ moisture content doesn’t exceed 19%.
Use soap and water to clean equipment, skin and clothing
