Read the painting tips at http://www.thisoldhouse.com/toh/article/0,,202236-3,00.html and seen some things did wrong but I accidently posted my help under discussion instead of asking for your help! We bought an old cedar house that had orignally had a dark stain on it. We sanded it down and then put on a solid stain which took about 5 coats before it quit soaking in the stain. Now most of it looks great however we have mildew growing on some of the clapboards including the majority of the northside. What is the best at this point to do? We are in the damp north-west. Suggestions will be greatly appreciated!
