6 Reasons Why You Should Invest in Weatherproof Outdoor Signs (and How to Make One)
Outdoor signs are more than just nameplates. They're 24/7 marketing tools that showcase your brand identity and make a lasting impression. But these signages can fade, warp, or break without proper weatherproofing, leading to costly replacements and lost brand visibility. A damaged or worn-out sign can also make your business appear neglected.
That's why investing in outdoor weatherproof signs is a smart business move. A well-designed weatherproof sign stays clear and professional through rain, heat, snow, or wind. It reinforces your credibility and attracts customers year-round, in any condition.
In this article, we’ll explore what makes a sign weatherproof, why businesses should invest in one, and how to create an outdoor waterproof sign for long-lasting durability.
What Makes Outdoor Signs Weatherproof?
Not all exterior signs are built to last, so it's essential to consider the materials and finishes used in weatherproof outdoor signs. Here are the top materials that can make a sign truly weatherproof:
1. Vinyl & PVC
The most durable materials for outdoor signage are vinyl and PVC. These materials are water-resistant, UV-resistant, and flexible, making them ideal for huge signages like wraps, banners, and billboards. Additionally, they resist cracking and peeling even under extreme sunlight.
2. Aluminum & metal composites
For signs exposed to rain and humidity, aluminum and meta composites make a great option due to being rust-proof and lightweight. Aluminum composite panels (ACM) combine aluminum with a solid core for extra durability, increasing its longevity and wind resistance.
3. Acrylic & polycarbonate
Signs prone to strong winds, like display panels and illuminated signs, can benefit from acrylic and polycarbonate. These shatterproof materials provide superior impact resistance, making them excellent for high-traffic areas.
4. Weatherproof inks & coatings
Use UV-resistant ink to keep your signage sharp for years and prevent fading from extended sun exposure. Protective coatings like lamination and clear varnishes add an extra defense against dirt, moisture, and temperature changes.
Why Businesses Should Invest in Weatherproof Outdoor Signs
A high-quality weatherproof sign is a long-term investment with various business benefits. Here's why it’s worth considering:
1. Long-term durability and cost savings
Businesses that invest in weatherproof outdoor signs can save money on maintenance in the long run. Unlike traditional signs, weatherproof signs also last for years and reduce the need for frequent replacements. Durable materials like aluminum, polycarbonate, and UV-coated vinyl protect against fading, warping, and cracking.
2. Enhanced brand visibility in any condition
A well-maintained outdoor signage keeps your business visible and approachable, regardless of the weather. According to the Sign Research Foundation, 36% of American consumers state that the quality of a sign influences their decision to visit a new store. Meanwhile, businesses see a 16% increase in weekly sales after implementing one major and two minor changes to their exterior signs.
These numbers show that customers often base their first impressions on your signage. Keeping your outdoor signs vibrant, legible, and professional-looking can especially maintain brand consistency and customer trust.
3. Protection against extreme weather events
Poorly made signages can be vulnerable to heavy storms, strong winds, and snowfall. However, weatherproof signs can withstand extreme weather, mainly when constructed with reinforced materials like polycarbonate and metal composites. It prevents damage-related expenses and safety risks from breaking or falling signs.
4. Customization and versatility for any business
Whether you run a retail shop, restaurant, or corporate office, you can customize outdoor weatherproof signs in varied sizes, styles, and finishes to meet your business needs. For instance, tailor promotional displays or storefront signs by keeping up with industry trends to meet your branding and location requirements.
5. Sustainability and eco-friendly options
Many weatherproof outdoor sign materials are recyclable or made from sustainable sources. Opting for durable signage also lowers frequent replacements, reducing waste and environmental impact. Consider partnering with reputable printing companies such as Intermedia Print Solutions for sustainable, eco-friendly custom printing that ensure quality and environmental responsibility.
6. Compliance with local signage regulations
Many cities regulate the durability and safety of outdoor signage. Weatherproof signs are more likely to comply with these requirements to prevent potential fines or the need for costly redesigns. By investing in weatherproof signage, you maintain a professional image and ensure brand recognition in all conditions.
How to Make an Outdoor Sign Waterproof
Make sure your outdoor sign remains durable, visually appealing and damage-free in the long term. Here are steps to create a weatherproof sign that lasts:
1. Choose the right material
The key to creating a durable outdoor sign is selecting the right material. For example, vinyl and PVC are waterproof and UV-resistant, making them ideal for large-format signs like banners and billboards. Meanwhile, aluminum and ACM panels are rust-resistant and lightweight.
In addition, polycarbonate and acrylic provide excellent impact resistance for illuminated signs. Laminated wood with a waterproof coating serves as a rustic yet long-lasting option, with the added protective layer enhancing durability.
2. Use weatherproof printing and finishing
Outdoor signs with weatherproof printing and finishing ensure they remain vibrant and durable. UV-resistant ink prevents fading from sun exposure, while protective laminates or varnishes guard against moisture, dirt, and temperature fluctuations. Reflective finishes also enhance nighttime visibility, ensuring readability in low-light and nighttime conditions.
3. Design for readability and impact
Well-designed signage should remain clear and legible regardless of the weather. High-contrast colors ensure readability in different lighting environments, while bold fonts improve visibility from a distance.
Keep text and graphics minimal to prevent clutter so your message is instantly understood. Consider LED-backlit signs or other illumination options for enhanced visibility at night. Optimizing your design this way will make it impactful and accessible to potential customers at all times.
4. Secure and install properly
Proper signage installation secures your outdoor sign in harsh environments. Use durable mounting hardware like stainless steel fasteners to prevent rusting, and opt for weatherproof adhesives for smooth surfaces like glass and metal.
Reinforced posts or brackets help prevent swaying and damage from strong winds, ensuring long-term stability. A well-installed sign extends its lifespan and reduces safety risks caused by loose or unstable signage.
5. Regular maintenance and cleaning
Preserve your outdoor sign's appearance and durability with cleaning and maintenance. Clean dirt and debris regularly using mild soap and water to prevent buildup. After extreme weather, inspect for any damage and reinforce loose fittings as needed.
Reapply protective coatings to maintain vibrancy and extend the sign's lifespan, making sure it remains professional-looking for years. With consistent maintenance, your sign will continue to represent your brand effectively and keep it attractive for years.
