Understanding Different Types of Outdoor Plastic Signs
Not all plastic is created equal! For outdoor signs, a few types stand out due to their excellent performance in various weather conditions. Knowing the differences will help you pick the best material for your specific needs.
Corrugated Plastic (Coroplast)
This is probably the most common type of plastic sign you’ll see, especially for temporary or event-based signage. Corrugated plastic is like cardboard, but made of plastic. It has a fluted or hollow interior structure that gives it strength while remaining lightweight and affordable.
Pros:
- Very affordable
- Lightweight and easy to handle
- Water-resistant
- Easy to print on
- Good for short-term use (e.g., election signs, yard sales)
Cons:
- Can become brittle in extreme cold
- May fade over time with prolonged, intense sun exposure
- Not the most rigid material for very large signs without additional support
Ideal for: Real estate signs, event directional signs, temporary business promotions, garden markers for annuals.
Expanded PVC (Sintra, Komatex)
Expanded PVC is a rigid, smooth, and dense foam board made of polyvinyl chloride. It’s much sturdier than corrugated plastic and offers a more premium look. It’s often used for more permanent indoor and outdoor signage where a professional appearance is desired.
Pros:
- Smooth, clean surface for high-quality printing
- Rigid and durable
- Good weather resistance
- Resistant to moisture and impact
- Can be routed or shaped for custom designs
Cons:

- Heavier than corrugated plastic
Ideal for: Permanent business signage, directional signs, menu boards, decorative outdoor signs.
Acrylic (Plexiglass)
Acrylic is a transparent or colored thermoplastic often used as a shatter-resistant alternative to glass. For outdoor signs, it’s typically used as panels where a clear or colored background is desired, often with vinyl lettering or graphics applied to the surface.
Pros:
- Excellent clarity and light transmission (for clear acrylic)
- Shatter-resistant compared to glass
- UV resistant varieties are available for outdoor use
- Sleek, modern aesthetic
- Can be edge-lit for illuminated signs
Cons:
- Can scratch more easily than PVC
- More expensive
- Can become brittle in very cold temperatures
- Requires careful handling to avoid cracking
Ideal for: High-end business signage, house numbers, modern garden plant labels, decorative plaques.
Aluminum Composite Material (ACM) – Dibond, MaxMetal
ACM is made of two thin aluminum sheets bonded to a solid polyethylene core. This creates a very strong, rigid, and lightweight panel that is excellent for outdoor use. It’s often considered a premium choice for long-lasting signage.
Pros:
- Extremely durable and rigid
- Excellent weather resistance, even in harsh conditions
- Lightweight for its strength
- Smooth surface for vibrant printing
- Resistant to corrosion and rust
Cons:
- Most expensive option among common plastics/composites

| Acrylic (Plexiglass) | 3mm, 6mm, 10mm | Moderate to High | Good (UV treated versions best) | Medium to High | Decorative signs, premium labels, illuminated signs |
| Aluminum Composite (ACM) | 3mm, 4mm, 6mm | Very High | Excellent | High | Long-term business signs, premium outdoor displays |
Essential Features for Your Outdoor Plastic Signs
Beyond the material itself, several features contribute to the effectiveness and longevity of your outdoor plastic signs. Let’s explore what to consider:
1. UV Resistance
The sun is a powerful force! Prolonged exposure to ultraviolet (UV) rays can cause inks to fade and plastics to become brittle, chalky, or discolored. When ordering or creating outdoor signs, always inquire about UV-resistant inks and coatings. This is crucial for signs that will be in direct sunlight for extended periods.
2. Weatherproofing
This goes beyond just being water-resistant. Your sign needs to withstand temperature fluctuations, humidity, potential frost, and wind. Materials like ACM and expanded PVC inherently offer better weatherproofing than thinner corrugated plastics, especially over the long term.
3. Thickness and Rigidity
The thickness of the plastic directly impacts its rigidity. For small garden markers, a thinner corrugated plastic might be fine. However, for larger signs, especially those that need to stand upright on their own or withstand significant wind, you’ll want a thicker material or a more rigid plastic like expanded PVC or ACM. Thicker signs are less likely to bend or break.
4. Printing Method
The way your sign’s message is applied matters.
- Direct UV Printing: Many modern sign shops use UV-curable inks that are printed directly onto the plastic. These inks are durable and resistant to fading.
- Vinyl Graphics: Cut or printed vinyl can be applied to the surface of the plastic. High-quality outdoor-grade vinyl is essential here, as cheap vinyl will crack and peel quickly.
- Screen Printing: A traditional method that can be very durable, especially for high-volume runs with specific colors.
For maximum longevity, especially outdoors, look for signs printed with UV-resistant inks or those featuring high-quality outdoor vinyl.
5. Mounting and Installation
How you plan to display your sign will influence your choice.
- Stakes: Corrugated plastic signs are often inserted into metal H-stakes or ground stakes.
- Screws/Bolts: Rigid plastics like PVC and ACM can be drilled and mounted with screws or bolts for more permanent fixtures.
- Adhesives: Some signs can be mounted with heavy-duty outdoor adhesives, though mechanical fastening is generally more secure for long-term outdoor use.
- Chains/Zip Ties: For hanging signs, ensure there are pre-drilled holes or strong grommets.
Consider the conditions – for windy areas, ensure your mounting method is robust and secure.
DIY Plastic Signs for Your Garden and Home
You don’t always need to buy custom-made signs! Many easy DIY projects can utilize plastic materials for functional and attractive outdoor additions.
Simple Garden Markers
This is a fantastic and eco-friendly project! You can use scrap pieces of corrugated plastic or even old plastic containers cut into strips.
Materials:
- Scrap pieces of corrugated plastic (or sturdy plastic containers)
- Permanent markers (weatherproof outdoor markers are best, like Sharpie Extreme or paint pens)
- Scissors or a utility knife
- Sandpaper (optional, for smoothing edges)
- Ground stakes (for larger markers)
Steps:
- Cut your material: Cut the plastic into desired shapes and sizes for your plant labels. Rectangles are easy for writing, but you can get creative! If using containers, ensure the plastic is thick enough.
- Smooth edges: Lightly sand any rough edges if desired.
- Write your labels: Clearly write the name of your plant (e.g., “Basil,” “Tomatoes,” “Zucchini”). For added durability, consider using a stencil or painting the background first.
- Apply if needed: For very small labels, you might just stick them into the soil. For larger or taller plants, attach the label to a small piece of wood or plastic stake that can be inserted into the ground.
Tip: For even greater longevity, consider using an outdoor-grade clear spray sealant over your writing once it’s completely dry. For truly vibrant and lasting color, look into using permanent paint pens designed for outdoor use.
Custom Planter Labels
If you have a collection of pots or containers, custom labels can add a professional and personal touch.
Materials:
- Expanded PVC sheet (can be cut to size at hardware stores or with a good saw) or rigid plastic sheets.
- Outdoor-grade paint or vinyl lettering
- Drill (if you plan to attach them)
- Outdoor sealant (optional)
Steps:
- Cut to size: Cut the PVC or plastic into strips or rectangles that fit the aesthetic of your planters.
- Decorate: Paint the surface with outdoor-safe paint or have outdoor vinyl lettering made for your plant names.
- Seal (optional): Apply a clear outdoor sealant for extra protection.
- Mount: You can either insert them directly into the soil (if stiff enough) or drill a small hole and attach them to the planter with wire or zip ties.
Upcycling Plastic for Signage
Be creative! Old plastic bins, sturdy plastic containers, or even thick plastic sheeting can often be repurposed into functional signs. Always clean them thoroughly and ensure the plastic is sturdy enough for outdoor exposure. You might need to prime plastic surfaces before painting them with outdoor-grade paints. This is a great way to reduce waste and save money!
For more durable DIY projects, consider purchasing small sheets of expanded PVC or acrylic. Many local plastics suppliers or even large hardware stores can cut these to size for you, making it easier to create custom pieces for your garden or yard.
Caring for Your Outdoor Plastic Signs
Even the most durable signs benefit from a little care. Here are some tips to help your plastic signs look their best and last longer:
- Regular Cleaning: Wipe down your signs periodically with a damp cloth and mild soap to remove dirt, pollen, and grime. This prevents build-up that can be harder to remove later and can obscure the message.
- Check Mountings: Especially after strong winds or heavy rain, inspect how your signs are attached. Tighten any screws or adjust stakes as needed to prevent them from falling or becoming damaged.
- Inspect for Damage: Look for any signs of cracking, peeling vinyl, or fading ink. Early detection can sometimes allow for minor repairs before the damage becomes significant.
- Consider Seasonal Storage: If you’re in an area with extreme weather (hail, heavy snow, or prolonged freezing temperatures), consider taking down more delicate signs during the harshest months. Corrugated plastic can become brittle in very cold weather.
- Avoid Harsh Chemicals: When cleaning, stick to mild soap and water. Harsh solvents or abrasive cleaners can damage the plastic surface or the printing.
For instance, if you have signs directing visitors to your “Compost Haven” or “Herb Garden,” a quick rinse with the hose and a gentle scrub with a soft brush can keep them looking fresh season after season.
Where to Get Your Outdoor Plastic Signs
You have several options when it comes to acquiring or creating your outdoor plastic signs:
- Local Print Shops: Many local sign companies specialize in creating custom signs. They can often print directly onto various plastic materials and can offer advice on the best type For your needs. This is a great way to support local businesses!
- Online Sign Retailers: Numerous websites allow you to design and order custom plastic signs online. You can often upload your own artwork, choose material options, and have them shipped directly to your door. Companies like Garvey Plastics offer a range of plastic materials suitable for signage, and many online printers use similar materials.
- Big Box Hardware Stores: Stores like Home Depot or Lowe’s often have a sign printing service where you can get basic corrugated plastic signs made. They also sell raw materials like PVC sheets and acrylic for DIY projects.
- Specialty Plastics Suppliers: For DIYers looking for specific types or larger quantities of plastic sheets, contacting a specialty supplier can be beneficial.
When ordering, don’t hesitate to ask about their printing process, the type of inks or vinyl they use, and their recommendations for outdoor durability. Asking questions ensures you get a product that meets your expectations.
