As the days grow longer and the event season shifts outdoors, brands, festivals and exhibitions look to create bold, memorable experiences in the open air.
But designing props for an outdoor space brings a unique set of challenges. Rain, wind, sun and even the occasional hailstorm can quickly turn a beautiful piece into a weather-worn relic. At Spur Creative, we specialise in building props and sculptures that don’t just look incredible, but also built to withstand the unpredictable British weather.
Here’s a behind-the-scenes look at how we weatherproof our outdoor installations for spring and summer events.
Choosing the Right Materials
The foundation of a durable outdoor prop starts with the right materials. For projects that need to hold their own against the elements, we often work with:
Fibreglass: Strong, lightweight, and highly weather-resistant. Fibreglass is a go-to material for large outdoor sculptures and props. It’s perfect for creating intricate shapes that still offer durability and strength.
Polystyrene (EPS Foam): For projects where weight is a concern (such as hanging installations or temporary displays), high-density polystyrene provides an excellent base. To make it outdoor-ready, we typically hard-coat it with resin or fibreglass layers. This adds a tough exterior that resists moisture and impact.
Metal Armatures and Frameworks: For structural strength, particularly with giant props or pieces designed for public interaction, we often fabricate internal metal frameworks. These hidden supports ensure that props remain stable, even in windy conditions or high-traffic areas.
Protective Coatings and Finishes
Once the core structure is in place, the next crucial step is finishing. We apply specialist coatings designed to protect props from UV rays, moisture, and temperature changes.
Specialist Paint Finishes: Outdoor props require more than a quick coat of emulsion. We use high-grade automotive paints and industrial coatings that are formulated for longevity. These paints not only deliver vibrant, eye-catching colour but also resist fading and peeling over time.
Weatherproof Sealants: Props destined for open-air settings often receive an extra layer of protective sealant. Sometimes a clear lacquer or a polyurethane coating to create an impermeable barrier against rain and humidity.
Texture and Surface Treatments: In some cases, we apply textured finishes that mimic stone, wood, or metal. This offers the beauty of natural materials without the vulnerability. These faux finishes are not only visually stunning but also highly durable against outdoor wear and tear.
Built to Last (and Travel)
Another advantage of our weatherproofing techniques is flexibility. Many outdoor installations need to be transported between sites for tours, exhibitions, or promotional campaigns. By designing with lightweight materials like fibreglass and reinforced polystyrene and by adding protective finishes, we ensure that props are tough enough to travel without losing their impact.
