What You'll Learn
Use UV-resistant paint
To create long-lasting outdoor signs, selecting the right paint is essential. UV-resistant paint will protect your sign from fading and deterioration caused by the sun's ultraviolet rays. Here are some tips and suggestions for using UV-resistant paint:
Choose UV-Resistant Paints:
Selecting paint with UV inhibitors and stabilizers is crucial for outdoor signs. These paints provide long-term protection against sun damage while also offering a vibrant finish. High-grade paints often include anti-corrosive properties, which are essential for maintaining the structural integrity of metal signs. When choosing paint, opt for superior-quality options designed for exterior use. These paints contain pigments that are more resistant to UV radiation, significantly reducing the rate of fading.
Types of UV-Resistant Paints:
For wooden signs, consider using exterior acrylic latex paint. It adheres well to wood, dries quickly, and can withstand harsh weather conditions. Seal the painted sign with a UV-resistant polyurethane or spar varnish to add an extra layer of protection. For metal signs, polyurethane paint is an excellent choice as it provides a durable barrier against moisture and UV rays.
Application Techniques:
When applying UV-resistant paint, follow these steps: First, prepare the surface of your sign by sanding it until smooth. Clean the surface to remove any dust, dirt, grease, or old paint. This preparation ensures that the new paint adheres well. Then, apply a primer designed for the specific material of your sign, such as wood or metal. After priming, you can start painting with your chosen UV-resistant paint.
Additional Protection:
While UV-resistant paint provides a strong defence against UV rays, you can further enhance the protection of your sign. Consider applying a clear coat or sealant over the painted surface. This extra layer will contain the colour and provide added protection against wear and tear. Additionally, if your sign is exposed to harsh weather, you can install a cover, canopy, or enclosed shelter to protect it from rain, snow, and extreme sunlight.
Remember, when creating outdoor signs, using UV-resistant paint is a crucial step to ensure the longevity and vibrancy of your signs. By following these suggestions, you can effectively protect your signs from the damaging effects of UV radiation.

Seal with a UV-resistant varnish
To ensure your outdoor sign is protected from the elements, sealing it with a UV-resistant varnish is essential. This clear coat or sealant will act as a barrier, safeguarding your sign from moisture and harmful UV radiation.
When choosing a varnish, opt for a high-quality, UV-resistant option that is suitable for the material of your sign. For wooden signs, a polyurethane sealant is an excellent choice as it provides a durable barrier against moisture and UV rays. Apply at least two coats, following the manufacturer's instructions for drying times, to ensure complete protection. If you're using a wood like pine, it's a good idea to sand it to ~120 grit before applying the varnish to ensure the surface is smooth and ready for treatment.
For metal signs, a UV-resistant coating or paint is crucial. The sun's ultraviolet rays can cause colours to fade and materials to degrade, so selecting a varnish with UV inhibitors and stabilizers will provide long-term protection for your sign. These coatings act as a shield, preserving the sign's vibrancy and integrity.
In addition to choosing the right varnish, proper surface preparation is key. Before applying any sealant, ensure the surface is clean and free of dirt, grease, and old paint. This will allow the varnish to adhere well and provide effective protection.
By sealing your outdoor sign with a UV-resistant varnish, you can be confident that your sign will withstand the elements and maintain its aesthetic appeal for years to come.

Protect with a cover or canopy
If you want to protect your outdoor signs from UV damage, one option is to install a cover or canopy. This is a good way to protect your signs from the elements, including rain, snow, and sunlight.
There are a few options for installing a cover or canopy. If you have the space and budget, you can install an enclosed shelter, such as a carport-style shade structure. This will provide the most protection from harsh weather conditions. If you're looking for a simpler solution, you could try a tarp or canopy that covers the signage. This will protect your sign from direct exposure to rain and snow, but it may not provide as much protection from sunlight.
It's important to consider the placement of your sign when choosing a cover or canopy. If your sign is in an area prone to high winds, you'll need to use heavy-duty mounting hardware to secure the cover or canopy.
In addition to installing a cover or canopy, you can also use a protective coating or sealant on your sign to provide extra protection from moisture and UV radiation. This will help to extend the lifespan of your sign and keep it looking new.
Bringing signs indoors during extreme weather events, such as storms, is also recommended to prevent damage. Regular maintenance and cleaning will also help to extend the lifespan of your outdoor signage.

Choose the right materials
When creating outdoor signs, it's essential to choose materials that can withstand the elements and protect your sign from damage. Here are some tips to help you select the right materials for UV-safe outdoor signs:
Wood
If you're creating a wooden sign, choose a type of wood that is suitable for outdoor conditions. Some good options include cedar, redwood, or treated pine due to their natural resistance to decay. Before painting, prepare the wood by sanding it until smooth and then cleaning off any dust. It is also recommended to seal the wood with a quality primer, especially if you plan to use acrylic paint.
Paint
Select a paint that is specifically designed for outdoor use. Acrylic paint is a popular choice for its water-resistant properties, vibrant colours, and quick drying time. However, it may not be the best option for long-term UV protection. Oil-based paints offer better durability and weather resistance but require longer drying times. Exterior latex paint is another option that offers flexibility and resists cracking while being easy to clean with water.
When choosing paint, look for options with UV inhibitors and stabilizers, especially if you're creating metal signs. These paints provide long-term protection against sun damage and often include anti-corrosive properties, which are crucial for maintaining the structural integrity of the sign. High-quality paints with higher pigment concentrations are also more resistant to UV radiation, reducing the fading rate.
Sealants and Coatings
After painting your sign, it's important to apply a sealant or coating to provide an extra layer of protection. Polyurethane sealants, both oil-based and water-based, are excellent choices for creating a barrier against moisture and UV rays. Apply at least two coats, following the manufacturer's instructions for drying times. You can also use a clear UV-resistant varnish or epoxy, similar to what is used for small boats, to protect against UV rays and water damage.
Additionally, consider using a UV-resistant coat or spray specifically designed for outdoor signage. This will not only protect against fading caused by sunlight but also help prevent water damage.
Covers and Shelters
If your sign is exposed to harsh weather conditions, consider installing a cover or canopy to protect it from rain, snow, and direct sunlight. A simple tarp or a more complex structure like a carport can provide adequate shelter. Alternatively, you can place your sign behind a plastic shield or enclose it in a transparent box for added protection.
Remember, the key to creating long-lasting outdoor signs is to choose quality materials, understand the weather conditions your sign will endure, and select the appropriate treatments to combat fading and damage.
