Can I use epoxy coatings and adhesives on pressure treated-wood?

New pressure-treated wood has a high moisture content.  Until the wood has dried sufficiently it can cause adhesion failures both for surface coatings and adhesives.  

The wood will eventually dry to an acceptable moisture content which can be followed with a moisture meter.  At that point, adhesives can be used successfully with standard surface preparation.  Metal salts can be left behind on the surface and still cause epoxy coating adhesion problems. If white or green residue is visible, it should be scrubbed off before applying a sealer or coating.
