I am new to this but I sure need some good advice. My wife and I are adding on to our home. We ordered douglas fir beams out of S. Dakota. The beams are hand hewn and were cut out of standing dead timber. I received the beams last August and stained them. I stacked them in my garage and they have dried and checked. Some of these beams will go inside the house and some will go outside and be exposed to some weather on the porches. How do I seal the beams so that they look like they are 100 years old and at the same time prevent the outside beams from deteriorating in the weather. Restaining the checks is not a problem, I just don’t know how to seal the beams. I have read about a 50/50 mixture of boiled linseed oil and turpentine. Is this the best to use?
Thanks in advance,
