Yes, use VNC Ext. Penetrating WaterProofer on the outside on plywood or solid wood if it's freshly sanded, clean, dry, and unpainted. Because it is clear, it will protect from moisture for about a year or two but will not block UV from the sun. A better product is our VNC PolyWhey Ext. Stain which comes in colors. The pigments are what block UV much better and will provide a longer lasting finish.For the inside, use our AFM Dynoseal which is a waterproofing membrane that was made for below grade applications, roofing, fence posts and raised garden beds. It will protect the inside walls from moisture and poop.
