Kinds of Exterior Plywood Used for Yard Ornaments

Avoid plywood that is warped or stained.

Several types of plywood are used for yard ornaments, depending on budget and usage. Commercial yard ornaments that are rented out are usually made from the most durable types of plywood, because they are almost constantly exposed to the elements. Regular exterior plywood is suitable for seasonal yard ornaments.

Plywood

Yard ornament signs are typically made from B/C exterior grade plywood. This wood is inexpensive, widely available and easy to cut. Exterior grade plywood is harder and less porous than interior plywood, to withstand exposure to moisture and wind. Pressure-treated plywood is also available, although it is not necessary.

Medium Density Overlay

Plywood with a medium density overlay is even more weather resistant, making it a good choice for signs that will be displayed for a long time. The smooth coating on MDO plywood ensures that paint adheres evenly; paint applied to MDO plywood is three times more durable than paint used on regular, exterior plywood, according to the Canadian Plywood Association.

Plywood Sanded Project Panels

Plywood sanded project panels are plywood pieces that have been sanded to a soft finish, reducing the risk of splinters. The panels are smooth and ready to prime and paint, eliminating the need to apply a wood putty.

Considerations

Plywood that is 1/2-inch to 5/8-inch thick is the preferred thickness for yard ornaments. Thicker plywood may be more durable, but it will also be heavy and cumbersome. Regular exterior plywood may have rough areas or minor imperfections. A wood putty spread over the wood's surface can smooth it out. A high quality primer ensures that paint adheres smoothly.
