Clean the surface with Sashco’s CPR first to kill the existing mold. Then, apply a fresh coat of stain boosted with M-1 for added protection from future mold growth.
Sounds like you have mold UNDER the surface of the stain, which – unfortunately – is harder to treat, but must be treated in order to prevent things from getting even worse and leading to rot and decay. You will need to remove the stain and start from scratch in that area. Give a call to one of our log home finishing guides at 800-767-5656. They’d be happy to look at some photos with you, troubleshoot, and help you put a plan of action together.
In short: it helps keep ugly growths off your log home. M-1’s technology is environmentally friendly and compatible with virtually every available stain formula tested. Apply at initial application and on every maintenance coat to renew protection.
