Wood signs are timeless. Their appeal can add warmth, character, and a natural aesthetic to a business or property. From rustic storefronts to restaurants, campgrounds, and other outdoor spaces, a wood sign offers plenty of design possibilities.
However, outdoor signs are often exposed to snow, rain, wind, sunlight, changing temperatures, and other harsh weather conditions. Not all woods perform equally well outdoors, and choosing the right type of wood can make a big difference in how well your sign holds up to the elements.
So, what type of wood is best for outdoor signage? Let’s look at some of the most popular options and what you should consider before choosing one.
What type of wood is best for outdoor signs?
One of the best all-around choices for wood outdoor signs is western red cedar, which balances durability and cost-effectiveness. However, no one type of wood is best for every outdoor sign. Some other popular options include redwood, MDO plywood, and teak.
Let’s take a closer look at each type:
Cedar
Cedar is a popular choice for outdoor signs because it naturally resists moisture, rot, and insects. It is relatively lightweight and easy to work with, making it a versatile choice for a wide range of sign designs.
Western red cedar, in particular, is well suited to outdoor signage. Its attractive grain and warm colour can create a natural or rustic appearance, while the wood can be painted or stained to achieve a variety of looks.
Redwood
Redwood is another durable option for outdoor signs because it naturally resists moisture and decay. Its rich, reddish colour and distinctive grain can give a sign a warm, natural look, and it can be stained or finished to enhance its natural beauty. However, redwood can be more expensive and less readily available in some regions, so it’s less practical for certain projects.
MDO Plywood
MDO (medium-density overlay) plywood is the industry standard material for painted outdoor signs. It features an exterior-grade plywood core with a weather-resistant resin overlay, creating a smooth, durable surface that helps resist cracking and warping. This smooth surface makes MDO particularly well suited to paint, lettering, and graphics.
Teak
Teak is an exceptionally durable hardwood that naturally resists moisture, insects, and decay. Its dense structure and natural oils allow it to withstand severe weather for decades, and it has a distinctive appearance that develops a unique character as it ages. However, it is generally more expensive than other wood options, making it a better fit for premium or specialty projects.
Do outdoor wood signs require maintenance?
Yes, outdoor wood signs require some maintenance to keep them looking their best and to help protect them from the elements. Before a wood sign is installed outdoors, it should be properly finished for exterior use. Depending on the type of wood and the desired signage, this may include applying exterior paint, stain, or another type of protective finish. These coatings help protect the wood from moisture, sunlight, and general weathering.
Once installed, wood signs should be inspected periodically for fading, peeling, cracking, moisture damage, or other signs of wear. Keeping the sign clean also helps maintain its appearance. Over time, the finish may need to be touched up, recoated, or refinished to continue providing protection. The frequency of maintenance depends on the type of finish, the type of wood, and how much exposure the sign receives to sunlight and moisture.
How long do outdoor wood signs last?
Outdoor wood signs last anywhere from 5 to 20 years or more, depending heavily on the type of wood, the quality of the finish, and local weather conditions. Durable woods such as cedar, redwood, and teak can provide particularly long service when properly maintained. Signs exposed to direct sunlight, moisture, and extreme temperature changes may require more frequent maintenance or refinishing to help expand their lifespan. With the right material, proper care, and regular maintenance, some wood signs can last for several decades.
