Which Product Offers the Best UV-Resistant Roof Protection?

UV-resistant options at a glance

Two resin systems in the range include UV-resistant properties: Prolux, a polyurethane coating, and Icrystal, a clear epoxy resin. Prolux is formulated for tough surfaces including concrete, fibreglass, ceramic, plastic and properly prepared steel. Icrystal is commonly used on wood, concrete, ceramics and technical fabrics such as glass fibre.

• Prolux – pigmented polyurethane coating with gloss or satin finish, built for abrasion and weather resistance.
• Icrystal – transparent epoxy with a UV filter to reduce yellowing and a scratch-resistant surface.

For a van roof, the difference often comes down to whether you want a coloured protective layer or a clear coating that preserves the look beneath.

Application and surface preparation

Both products are two-component systems and require careful mixing before use. Prolux uses a 2:1 mix ratio and is designed for high-traffic or damp conditions, while Icrystal can be applied up to 1.5 cm per layer and typically cures in around 24 hours. Always check that the roof surface is clean, dry and compatible before starting.

• Remove dirt, grease and loose material before coating.
• Ensure the van roof is dry and, for metal areas, properly primed if required.
• Work in a ventilated area and follow the product instructions for mixing and application.

When UV resistance matters most

UV resistance becomes important when a van roof is parked or used in direct sunlight for long periods. Without it, some resins can yellow, chalk or lose flexibility after repeated exposure. A UV-stable coating helps maintain the roof’s appearance and weather protection over multiple seasons.

This is especially relevant for work vans, campers and vehicles stored outdoors where the roof receives constant sun and rain. A quick visual check for dulling or colour shift can indicate when a recoat is needed.
