It's important to not use any type of coating that produces acetic acid as it cures, such as acetoxy silicone. Acetic acid will eat copper traces away very quickly - even if the PCB is exposed only to the fumes. Real PCB conformal coating will obviously be safe, but be careful with anything else - like a tube of silicone sealer from a hardware store.
There are a few types of conformal coatings, and blocking moisture is typically the most common use for just about all of them. Easiest to use would probably be a brush-on or spray-on acrylic.

I used this Acrylic Conformal Coating on a few boards for my holiday lights display that were left in outdoor enclosures at the mercy of midwest winters. No moisture problems with this stuff.
