There is no such thing as dry rot. All rot is wet rot. People have called it dry rot because it's usually only discovered after it has dried out. Tiny bugs and fungus are what cause wood to rot- they eat the wood. Like any living thing, they need food water and oxygen to live. The wood is the food and without water and oxygen, they won't live in the wood. If wood gets wet, it will be a habitat for those that eat it. That's why pressure treated wood contains pesticides and copper-- to kill the things eating the wood and remove the oxygen.

There are rotted wood treatments which are basically a diluted exterior glue, sometimes containing a pesticide, and often containing a "primer" that will bond to the epoxy many people use as a filler to replace the rotted wood.
