PU (polyurethane) coatings are a popular choice for providing long-lasting and waterproof finishes to floors in both domestic and industrial settings. Their adaptability makes them well-suited to a wide variety of surfaces and environments.
What Makes PU Coatings Stand Out?
Polyurethane floor coatings are celebrated for their durability and versatility. They form a tough surface layer that withstands frequent foot and vehicle traffic, making them a reliable option for high-use zones such as garages, warehouses, or external areas. Their resistance to UV light, abrasion, and general weathering means PU coatings remain protective even outdoors. Furthermore, these coatings deliver a smooth, waterproof finish that is easy to clean, helping to protect underlying materials from moisture and stains.


Typical Surfaces and Applications
PU coatings can be applied over a range of properly prepared substrates, including concrete, fibreglass, ceramics, plastics, and metals. This versatility makes them suitable for everything from tiled interior floors to driveways, workshops, and industrial spaces. For a comprehensive solution, the Prolux PU coating offers protection for both interior and exterior surfaces, including driveable areas.
Buying and Application Tips
- Ensure your floor or surface is dry, clean, and properly prepared for the best adhesion.
- Many PU systems are two-component and need careful mixing before use; always follow the manufacturer’s instructions for ratios and application method.
- Choose between gloss or satin finishes and a variety of colours to suit your project.
- Allow proper curing time before subjecting the area to heavy traffic or moisture.

When This Matters
PU coatings are especially valuable in situations where you require a hard-wearing and waterproof floor that stands up to daily wear, such as garages, commercial kitchens, and outdoor walkways. They’re also ideal in damp or high-traffic areas needing extra protection.
