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.

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.
