imbabci2 14 Report post Posted July 3, 2008 I have 30 year old oil stained cedar lap siding on my home. It has blackish spots, looking a bit like mildew, on many areas. Many of the nails are popping out. Many knot holes are missing. it appears very dried out. There is also some edge curling on the sunny sides of the house. I've been told by a friend that cedar can be saved: bleach it, caulk the bad areas, then apply a couple coats of stain. Would anybody care to comment?

RPetry 564 Report post Posted July 3, 2008 Clean it well. Sodium percarbonate and/or 3% bleach and a touch of soap. Brighten /neutralize with citric or oxalic acid. Allow to dry. Apply as much paraffinic oil stain as the cedar will take. At least two apps. Share this post Link to post Share on other sites
