Last week we built a brand new 10x16 deck onto the back of my house, we spent the extra $ and went with western red wood cedar. I had no idea we were supposed to use screws and the hardwood store sold us galvanized nails..electroplated, not hot-dipped! I had a carpenter in to do the railings who mentioned the nails would turn black now that I research it seems to be a big no-no. Is it worth taking all boards off at this point? There are no rails up yet, I hate for my cedar to blacken...I read I could use a nail puller has anyone done this? I tried a mallot last night tapping boards from underneath and only 1 nail stayed in, the other 2 came right through the cedar. (4 ft under deck so easy access) Maybe a crow bar is better? Not sure if its worth the time...any suggestions/opinions appreciated! Oh, the boards are staggered and the longest 12 ft has about 36 nails in it do the math...i cant afford to replace 1/2 the boards either.
