Why Should Checks Be Sealed?

checkmateUpward facing checks will collect water increasing the interior moisture content of the log. This eventually results in rot and insect damage. They also provide nesting sites for carpenter ants and other insects. If left unattended, checks can continue to grow until they produce an opening into the interior of your home.

Check Mate 2 is specifically formulated to meet the particular requirements for sealing checks that appear in log homes. Check Mate 2 comes in various colors and you can 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. That way the Check Mate 2 will blend in with surrounding stained wood.

Like other flexible sealants Check Mate 2 should be used in conjunction with Backer Rod whenever sealing a gap that’s more than ¼ inch wide.
