Weatherall 1010 Chinking Specifications
Weatherall 1010 Chinking is a flexible, mortar-textured sealant
specifically designed for use in log homes. Formulated from a
thoroughly tested blend of latex acrylics chosen for superior
weathering, adhesive and flexing characteristics, Weatherall 1010
Chinking replaces mortar-based chinking, mastics and glossy caulks.
Available
Colors: Standard Grey, Southern Grey, Light Grey,
Standard Tan, Western Ton, Woodtone, Stone.
Weatherall 1010 Chinking is used in log joints where a positive,
weather-tight seal is needed and a neat, mortar-textured finish is
desired. Weatherall 1010 Chinking is avail-able in a wide range of
colors to either imitate the traditional look of mortar chinking or to
blend in with the tones of the wood. Weatherall 1010 Chinking makes an
excellent restorative coating over previously applied mortar chinking,
mastics or caulks. Weatherall 1010 Chinking is also the easiest
chinking to apply for the do-it-yourself applicator.
- Stays Flexible: Weatherall 1010 Chinking provides a
resilient, mortar-textured finish that stays flexible and expands or
contracts with the log movement.
- Seals out Air and Moisture:
Weatherall 1010 Chinkin9 provides a simple, effective seal that
eliminates air and water infiltration and significantly improves energy
efficiency.
- Durable: Weatherall 1010 Chinking forms a tough,
damage-resistant surface that withstands wind-driven rain, salt spray
and most chemicals. It has excellent weathering properties in
temperature extremes and excellent color retention.
- Attractive:
Weatherall 1010 Chinking adds a beautiful, finished appearance to log
walls. It does not have the messy synthetic appear-once of some other
sealant materials.
- Quick Drying: Weatherall 1010 Chinking
cures more quickly than other brands of synthetic chinking;
consequently, it does not remain tacky and is not prone to attracting
job-site dust and other air borne contaminants.
- Non-Toxic:
Weatherall 1010 Chinking is safe for both interior and exterior use and
has no odor when cured.
- Fully Warranted: Weatherall 1010
Chinking comes with a full 5 year warranty
Texture: Semi-matte sand texture. Can be tooled to achieve a
semi-smooth to rough finish.
Recommended Thickness: Finish troweled thickness should be
from 1/16 to 1/4 in. across the face of the backer rod.
Drying Time: Weatherall 1010 Chinking will be skinned over on
surface in 20-30 minutes, and will be surface dry in 8-10 hours under
normal conditions. It will be fully cured in 7-10 days. Actual times
will vary depending on temperature and relative humidity. It should be
protected from contact damage for 2-3 days after application.
Viscosity: 250000 cps + - 10000
Density: 14 lbs/gal + pH: 9+
Stability: One year shelf life when stored in a tightly
sealed container at moderate temperatures.

The following guide is offered to assist in estimating coverage and
quantities required. Measure the total number of lineal feet of log
joint, exterior and interior, and estimate the average width of the
finished chink joint. Remember to include corners, door and window
bucks, gable lines, purlins and joist notches, etc., in addition to the
horizontal chink lines.

Surface Prep
The logs must be clean, structurally sound, dry (19% moisture
maximum) and free from any grease, paraffins1 oils or other
contaminants that could inhibit the ability of the chinking to
penetrate and bond to the wood fibers.
Note: Some wood finishes will leave a film on the wood
surface that can adversely affect the adhesion of the chinking.
Finishes that contain oils, petroleum distillates, paraffins or any
other finish that is film forming or very freshly applied may not allow
the chinking to properly bond. Applying any wood finish, other than
Weatherall Clear UV GUARD Wood Finish or Log Guard, on top of the
chinking will leave a discoloration on the chinking. Weatherall's Clear
UV GUARD Wood Finish makes an excellent maintenance coating and will
not discolor the chinking.
If you have a previously applied wood finish, or are in doubt as to
the compatibility of your finish with the chinking, contact Weatherall
Technical Support.
Application Temperature
Wealtherall 101 0 Chinking should not be applied when temperatures
are below 400 F, or when subfreezing temperatures are expected within
48 hours of application. Avoid chinking in the rain or when rain is
imminent.
Note: There may be occasions when chinking in subfreezing or
rainy weather is unavoidable. In such cases, contact your Weatherall
representative for specific recommendations.
When chinking in very hot weather; it is recommended that the
chinking be applied to the shaded side of the house.
Backer Rod System
When applying Weatherall 101 0 Chinking to new construction or to
previously unchinked structures, it must be applied over a triangular
shaped, closed-cell, non-adhesive backing such as Weatherall Tn-Rod.
This type of backer-rod system provides several critical advantages.
- It creates the ideal slip joint design which allows only two
points of adhesion: to the wood surface at the top and bottom of the
joint.
- The rounded edges create a wider footprint at the top
and bottom where the chinking is in contact with the wood.
- It
provides a flat, even surface over which to tool the chinking.
- It
Is water resistant and highly insulating.
Note: In joints less than 3/4 inch wide, closed cell,
round polyethylene rod may be used. In this case, it is important that
a minimum chinking thickness of 1/4 inch be maintained over the entire
surface of the joint. The effect will necessarily be a convex shape
over the round rod. Do not cut the round rod in half and place the cut
side out to simulate Tri~Rod. The cut face will not release the
chinking and it may fail at the edges.
Chinking Application
Weatherall 1010 Chinking can be applied with a bulk loading caulking
gun, grout bag or commercial chink pump. The applied bead should be
firmly trowled into the edges to insure complete edge adhesion. Use of
a 50/50 mixture of isopropyl alcohol and water as a release agent will
allow the trowel to glide smoothly over the chinking. Spray release
agent on bock of trowel, not directly on chinking.
Note: UV GUARD Wood Finish or Log Guard should be applied
prior to chinking for two reasons:
- UV-GUARD Wood Finish acts as a primer and creates a better
bonding surface to chink to.
- Pigmented stains subsequently
applied will discolor chinking. Maintenance coats of Clear UV GUARD
Wood Finish or Guard will not discolor chinking.
