Brand New Unstained Deck's Black Spots
Our new (unstained) cedar deck has been in for 9 days now and it's already got several black spots (see close-up). These black marks shouldn't have appeared so fast, should they? It looks awful!
What is this? Please, we need ideas on what to do. Is this the contractor's fault; something wrong with the cedar? We had planned to let the deck age for a couple of months, so that it will accept stain well, and then stain it.
Thanks in advance for any help you can share!
