Two-Component Aliphatic Polyurethane Coating with Excellent UV and Yellowing Resistance

← Back to Cleaning Painted Floors

A two-component aliphatic polyurethane coating is a protective surface finish formulated to resist UV exposure and yellowing over time. It is typically mixed as two pre-measured parts before application and can be used on concrete, fibreglass, ceramic, plastic and properly prepared steel. When applied to floors, it forms a tough, abrasion-resistant film that supports easier cleaning and maintenance, especially in areas exposed to natural light or moderate weathering.

For painted floors that need a stable topcoat, this type of finish can keep the surface looking consistent while making routine cleaning less demanding.

What a two-component aliphatic coating does

A two-component aliphatic polyurethane coating is supplied as two pre-measured parts, typically mixed at a 2:1 ratio before application. Once cured, the film resists ultraviolet light and the gradual yellowing that can affect some clear or pale finishes.

Suitable for concrete, fibreglass, ceramic, plastic and properly prepared steel
Available in gloss or satin, with optional anti-slip treatment
Designed for floors subject to foot traffic and mechanical stress

Using it on painted floors

On a painted floor, this coating typically acts as a protective top layer rather than a full repair system. The existing paint should be firm, clean, and free from loose or flaking sections; a heavy-duty scraper can help remove damaged material before application.

The Prolux PU coating is one example in this category, and it is offered in gloss or satin finishes. Because the cured film is abrasion-resistant, it can reduce how often a painted floor needs heavy cleaning in busy or damp areas.

When UV and yellowing resistance matters

This property is most useful where a coated floor receives regular natural light, such as entrances, conservatories, or commercial spaces with large glazing. Without UV-stable chemistry, a clear or light-coloured finish may change in appearance more readily.

If the area is also damp or carries foot traffic, the same coating can help protect the painted surface below while keeping routine cleaning straightforward.
