What is High Performance
We talk a lot about high performance around here, but what the heck makes chinking high performance?
Chinking should be flexible, elastic, and adhesive. Many sealants are flexible, adhesive, or elastic. It is the combination of all three together that leads to high performance, meaning durability and longevity you can trust.

Common Questions From Our Network of Pros
You have two options:
1) apply a skimcoat of chinking over top of the original. It doesn’t need to be thick. Make sure you smooth it out for best appearance; or
2) follow our directions on how to make your own chink paint using water and Log Jam chinking. This can be applied with a paint brush to restore the original color.
If you used Sashco’s stains and clear coats, that’s a resounding YES! If you used a brand that we don’t make, give a call to our friendly and cheery Customer Service Team. We’ve tested several brands out there and usually have a good idea on whether or not they’ll work together.
That’s the best idea if you want to avoid repair work, yes. Of course, on a newer log home, this is going to be more important. On an older log home that has done most of its drying and moving, it’s still best but usually not as critical. The risk of widespread repairs is lower on an older, more established and “settled in” log home.
