Best Way to Protect CDX Plywood

The Best way to Protect CDX Plywood is the same way you would go about protecting any other type of wood product. Using primers, stain and paint are a good start for any plan to create strength for your home wood projects.

Protecting CDX Plywood from Water Damage (Waterproofing)


Many types of waterproofing are available to protect CDX plywood. It just depends what type of protecting you are looking for. The most usual types sold in home improvement stores, like Lowes and Home Depot is the paint-on or spray-on type of waterproofing. These typically are liquid latex substances applied to the surface of the plywood while wet.When they are left to dry, they form a plastic, protective layer. Penetrating oils and sealers are another form, and sheet plastics and interlocking membrane systems are available as well.


How to Stain CDX Plywood 



Using a damp cloth, wipe the cdx plywood to raise the grain of the wood to make sanding easier. Sanding with the grain, lightly sand the wood with the 120-grit sandpaper, then do the same with the 220-grit sandpaper. Sanding helps the paint to adhere to the cdx plywood. Clean the cdx plywood with a rag that has been soaked in denatured alcohol. Staining cdx plywood is a necessary step to prevent acid or oils from leaching from the board.

Using the paint roller, prime the cdx plywood. Once the primer has dried, sand again using the 220-grit sandpaper then clean off the sanding residue with a rag that has been soaked in denatured alcohol. You may apply a second and third coat if you feel it is necessary, sanding in between each layer.
