Conceal Textured Caulk for Wood delivers performance that’s hard to see. Conceal’s 7 colors blend in with the most popular stains used on log and wood homes. Conceal Textured Caulk for Wood’s light texture simulates the natural roughness of wood. The combination of color and texture makes it hard to see where the caulking ends and the wood begins. Instead, they just blend together. Although the caulking is hard to see, Conceal delivers performance.

SURFACE PREPARATION NOTES:
Best results are obtained when Conceal is applied to wood that has been previously coated with a compatible and thoroughly cured stain.
Conceal is not a chinking and should be used only in joints under 2” wide. If the joints are wider, we recommend Log Jam.
It is always best to install backer rod before caulking. Sashco strongly recommends the use of backer rod, especially if the home is new and/or the wood is subject to significant movement.
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.
BEST CONCEAL TEXTURED CAULK FOR WOOD APPLICATION USES:
- Log Stacking
- Filling Joints Between Logs
- Sealing Around Windows and Doors
- Filling Checks
CONCEAL TEXTURED CAULK FOR WOOD APPLICATION NOTES
When using 5-gallon pails, the Cox Bulk Loading Gun should be used. Use a caulking gun when using either the 29 oz. or 10.5 oz. cartridges of Conceal Textured Caulk for Wood. 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.
Conceal should be tooled directly after application to ensure good adhesion and a smooth looking bead. To ease the tooling process, mist Conceal with water. Conceal may be tooled with a damp foam paint brush. Work the material smooth, tooling Conceal tightly to the surfaces. Keep a rag handy for clean up.
Stainability
Conceal is Stainable with latex coatings after a minimum of 24 hours curing (longer on wider joints) and after 5 days curing with most oil-based coatings.
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 waste in drinking water supplies. Soap and water may be used for cleaning hands, surfaces and equipment. Solvents are not required for clean-up
Chinking and Sealant Calculator
What happens if I go less width than what the manufacturer recommends?
Not all logs on your home move at the same rate, some may move a lot and others barely anything. When they make the recommendation they figure out the most movement you would see out of two logs touching each other and recommend a joint size that will allow the stretch to happen without failure. Some people want the joint to be smaller due to cost or the look. If you took a 1.5" recommendation and went with 1" instead, you will notice a few more repairs over the years if you get two logs that really move. You are not likely to see failure everywhere if you were deep enough with the joint in the first place ( notice we are talking depth here...not the initial joint width question)
The smaller you make the width the more likely you will see failures or separation. In our experience we have seen good results if people use 2/3 of the recommendation...but we don't recommend pushing it further than that.
Not all logs on your home move at the same rate; some may move a lot and others barely at all. When they make the recommendation they figure out the most movement you would see out of two logs touching each other factoring in the size of the logs. They recommend a joint size that will allow the stretch to happen without failure. The sealants and chink are designed to strech 2.5x the joint size before failing. Big logs overall move more so require a bigger joint. If you short it too much there may not be enough material to handle the log movement.
Some people want the joint to be smaller due to cost or the look.
For Example: If you took a 1.5" recommendation and went with 1" instead, you will notice a few more repairs over the years if you get two logs that really move. You are not likely to see failure everywhere if you were deep enough with the joint in the first place ( notice we are talking depth here...not the initial joint width question)
The smaller you make the width the more likely you will see failures or separation. In our experience we have seen good results if people use at least 2/3 of the recommended joint size...but we don't recommend pushing it further than that.
Joint Width
Most manufacturers recommend 15% of the log diameter for joint size after the first drying season and up to 20% if it's in the first drying season.
Example: 10" log diameter x 15% = 1.5" recommended joint size
Want to go less? You can, but learn more if that is a good decision for you.
Lineal Footage
Take each wall and multiply by the number of rows of sealant high.
Example 40' long wall x 9 rows high= 360 lf . Then add your lineal footage from each wall together.
For corners add 30% to your height measurement.
For gable ends, count your rows and estimate each for length, then add together.
Joint Depth
Log Sealants are designed to stretch as your logs move. They need an appropriate width as above, but even more important they require enough depth (material) so as not to fail.
Recommended Depth:
Joint Width 1/2" or less= 1/4" depth
Joint Width 5/8" or greater= 3/8" depth up to 1/2" Learn More about playing with depth
*Note: Quantities are based on the provided measurements. Actual product required can vary based on real life thickness used and contours of the logs. All calculations based on the use of backer rod

Sashco Log Builder Caulking
Log Builder sealant is specifically formulated to absorb most log movement.
In the 1970s, log home owners everywhere were discovering that logs are in constant dynamic motion. They came to Sashco for help, and a few years later, Log Builder® sealant was born.

Its superior elasticity creates a tight seal that keeps out water, dust, bugs, and wind. **5 gallon pails are a special order Sealant Calculator & More Info
Dezerae McKay –
We got very lucky by calling in before we applied Thompsons Water Seal to the house. We didn’t know that if we did that, none of the caulking would stick to it. We switched our coatings to the Transformation Log and Timber one and it all worked together well. The Conceal looks very good, the texture is like wood and the color we chose blends in very well and picked up the stain too. Very happy with it, thank you and thanks for saving us from making a big mistake on the house.
