Did you stain the timbers yourself? We just had our house built on Vancouver Island and we have similar Douglas Fir timbers at front and rear of the home. The contractor used a Sikkens stain and a couple months later the timbers look terrible. Blotchy, what look like water stains, graying, even black spots. Can you tell me more about the staining process? our contractor is at a loss as to what happened or how to fix it. Much appreciated!
