Hi, we are currently purchasing a chestnut log home in NY and it hasn’t been stained (outside) for probably 20 years. It looks extremely weathered. In the spring I want to start prepping for stain and urethane but I’m unsure of the steps I need to take. I’m wondering if a pressure washer is sufficient to take off the old finish. Also, once the power washing is done, if that is sufficient, what cleaner should I use? I’m thinking of going with Sikkens as my stain. Thanks!
DO NOT power wash to remove the old finish. I would recommend grinding the logs to clean. You especially do not want to power wash if you are going to use Sikkens. Since it is an oil based stain it will not allow the logs to breathe and let any moisture out that will be driven deep into the wood fiber. Also do not use any urethane. I would recommend using a latex stain like Life Line from Perma Chink.
