HELP! Our clear cedar is turning black, we built the home 10 yrs ago. Used Sikkens Cetol 23 plus, applied 3 coats to front and back of the boards and then installed them on the house. Have reapplied Cetol 23 plus every other year since. Why is cedar turning black?? And what can we do to fix it?

Sounds like it was not completely dry or you power washed it first. You are probably going to have to strip the house and start over. Use a good quality latex stain made for log homes next time. Oil based stains like Sikkens can lock the micro moisture into the wood and cause that black you are seeing. Call Mike at 866-670-3020 for more information and possibly a visit.
