2 – Tool to ensure a tight seal to the
top and bottom of the caulk line
leaving at least 1/4” depth of
caulk in the center of the joint.*

next log and repeat. Don’t allow caulk
to skin over prior to stacking.

response to these moisture changes, moving more
than any caulk can possibly handle.
When this extreme movement occurs, it will cause
the caulk to fail either cohesively or adhesively.
If the failure is cohesive (caulk splits apart),
then the repair is performed by simply cleaning the
surfaces of the failed caulk and reapplying more.
If the failure is adhesive (caulk pulls cleanly away
from the substrate), it usually needs to be removed
and completely redone.
Warranty
Sashco Sealants warrants that Conceal will
stretch up to 100% of original joint size (± 50%)
and will not pull away or center tear when applied
in accordance to this Conceal Info Sheet (CNL-002).
If you are dissatisfied at any time with Conceal’s
performance in these areas, return proof of purchase
to Sashco. Limited to product replacement only.
Sashco warrants this product will substantially

thoroughly. Wash contaminated clothing before use.
INHALATION: Remove to fresh air.
INGESTION: If large quantities are swallowed,
DO NOT INDUCE VOMITING - seek medical help.

check to the appropriate depth. (See
Fundamental Application Guidelines.)
Checks
* NOTE: Use a bond breaker (i.e., backer rod) when significant log movement could occur. When movement is known to be minimal (as with many older homes)
using backer rod is still best, but usually less critical.
Methods of Application
When using 5-gallon pails, Sashco’s patented Snorkler
®
pumping system, grout bags, or bulk loading guns may
be used. Use a caulking gun when using either the 29
oz. or 10.5 oz. cartridges of Conceal. When using a
cartridge, cut the spout at a 45˚ angle to desired bead
size. Conceal requires no heating prior to application
but will dispense easier when kept warm before use.
Tooling
Conceal should be tooled directly after application
to ensure good adhesion and a smooth looking bead.
Conceal may be tooled with ordinary masonry-type
tooling blades, a wetted finger, or a damp polyethylene
foam brush.Work the material smooth, tooling
Conceal tightly to the surfaces, keeping a rag
handy for clean up.
Checks and Cracks
Logs tend to take on water from rain and snow
through cracks and checks; therefore, it is important to
pay close attention to these openings and prep and seal
them properly. Note: Most small checks should not be
caulked. Only the larger ones (1/4” or larger) should
be sealed with backer rod and caulk.
Joint Design
Joint width should be a minimum of 1/4”, but no
larger than 2”, and 4 times the anticipated joint move-
ment. For example, if you anticipate movement
of 1/8”, bead width should be about 1/2”.
For joints 1”
wide or more,
the depth
should be 3/8”
to 1/2”. The
depth of joints
less than 1”
wide should be
half the width but no less than 1/4”. (Joint depth, over-
all, should be between 1/4” and 1/2”.)
Clean-up & Disposal
Clean excess product off surfaces (before it cures)
with a putty knife and/or a damp rag. Dispose of
Conceal in accordance with local regulations. Do
not dispose of in drinking water supplies. Water may
be used for cleaning hands, surfaces and equipment.
Solvents are not required for clean-up.
Logs Move!
Occasionally, a small number of logs on any home
may undergo extreme movement. This movement is
a natural part of the logs moisture content adjusting
to their new settings. Most logs, as they dry (or go
through the repeated process of taking on and giving
up moisture), will undergo moderate levels of stress
on the caulks applied to them. An occasional log will
randomly and unpredictably twist, shrink or warp in
