Can I use Chinking or Sashco LogJam for my checks since I have some left over ?
You may but there is also a product specifically designed for filling cracks (or checks). Homeowners often want a contrast with texture and color when using chinking, but usually want the checks in the logs to blend in a little more. When filling checks, particularly on wide ones stuff some soft foam backing rod 3/8″ below the surface of the logs, then fill and smooth out. It doesn’t hurt to pour in some PeneTreat first. If your checks have been exposed to the weather, chances are some water has gotten in and the possibility exists some rot may be growing. PeneTreat will help kill the rot and help prevent it from getting any worse.
