Is Prolux PU Coating Suitable for Exterior Use?

← Back to Epoxy resin for concrete flooring

Polyurethane coatings such as Prolux are designed to resist UV rays and weathering, making them suitable for exterior use on surfaces including concrete. Prolux creates a durable layer that helps protect outdoor floors, driveways, and parking areas from sunlight, rain, and mechanical wear. With proper application and surface preparation, Prolux contributes to long-lasting, low-maintenance performance in open-air environments where resilience is needed most.

If you are considering refinishing outdoor concrete or tiled areas, selecting a coating that endures harsh conditions is essential. Prolux is formulated for just these settings, with attributes that meet the demands of external spaces.

Key Reasons Prolux Performs Outdoors

Prolux is an aliphatic polyurethane coating engineered to withstand exposure to the elements. Its resistance to UV rays helps minimise yellowing and surface degradation, preserving both appearance and integrity over time. Prolux also stands up well to rain, humidity, and rapid temperature shifts, reducing the risk of peeling or flaking. This makes it a reliable choice for patios, car parks, terraces, and other frequently used exterior surfaces.

Application Tips for Exterior Surfaces

Surface preparation is vital before coating with Prolux—cleaning, degreasing, and ensuring the substrate is fully dry results in better adhesion. The product is mixed in a 2:1 ratio and should be applied under stable weather conditions, avoiding damp periods. It is suitable for use on concrete, ceramic, plastic, and primed steel. For exposed driveways or parking areas, aim for multiple thin coats to boost durability.

For comprehensive results on bare concrete, complementing your topcoat with a dedicated primer such as the “Epoxyprimer” – Universal Water-Based Two-Component Epoxy Floor Primer is recommended.

When Outdoor Use Matters Most

Areas with constant sun exposure or frequent rain
Driveways, paths, and terraces needing a robust, non-yellowing finish
Commercial or public zones with high foot or vehicle traffic
