Perma-Chink Chink Paint
Backing materials are an integral part of a sealant system and should be used wherever possible. The overall performance of any sealant system depends on using the correct application thickness and proper backing. For small joinery, the most commonly used backing is round backer rod. It comes in a range of sizes and is relatively inexpensive. It is flexible and can be pushed into a crevice without needing to be nailed or stapled.
When joinery is too narrow to insert backing material, a narrow strip of water-resistant masking tape works well. Avoid masking tape that wrinkles when wet, because the wrinkles may show through the sealant after it has cured. A good option is to use pinstripe tape available at most automotive supply stores. The tape should be water-resistant so Energy Seal won't adhere to it, making it a suitable backing material. Pinstripe tape is available in widths as narrow as 1/8 inch.

Check Mate 2 is an outstanding water-resistant sealant that prevents water and air infiltration through pronounced cracks (called checks) in logs, timbers, and wood siding.
Sealing upward-facing checks is especially important in any location where they may accumulate water. If you leave these checks unsealed, they can become sites where rot may take hold. If you have old checks where rot is a risk, be sure to apply borates
before sealing with Check Mate 2.
Application
- Like other flexible sealants, Check Mate 2 should be used in conjunction with Backer Rod whenever sealing a
gap that is more than 1/4 inch wide. - Press the Backer Rod into the check about 3/8 to 1/2 inch deep to allow room for the Check Mate 2. Place masking tape on the outside of the check.
- Apply Check Mate 2 maintaining 3/8 inch thickness.
- Since Check Mate 2 comes in various colors, you should choose a color that is close to the color of the logs. However, if you are planning to stain over the Check Mate 2, choose a color that’s a shade lighter than the stain.
- Remove masking tape while Check Mate 2 is still wet.
