Using Prolux on Metal Surfaces

← Back to Moving 3D Floors

Prolux is a two-component polyurethane coating that can be applied to metal when the surface has been properly prepared and primed. On steel and similar metal surfaces it provides abrasion resistance and a durable finish, making it suitable for areas subject to mechanical stress, weathering or regular handling. The result is a protective layer that resists wear and UV exposure, but reliable adhesion depends on careful cleaning, rust removal and the use of a suitable primer before the coating is applied.

If you are working with steel panels, architectural trim or other metal elements, the preparation sequence matters more than the product alone. Prolux can bond well to properly prepared steel, but it is not a filler or rust converter. Degreasing, light abrasion and priming are the practical steps that turn a smooth metal surface into a reliable substrate for the coating.

Preparing metal for Prolux

Metal surfaces need a clean, stable profile before coating. Start by removing loose rust, mill scale, old flaking paint and any oils or grease. Light mechanical abrasion or a suitable surface preparation method can help create a key for the primer. The aim is to leave a dry, contamination-free surface; Prolux is designed for properly prepared steel, and adhesion will be weaker on dusty, oily or untreated metal.

Remove rust, scale and flaking old coatings
Degrease the surface thoroughly
Lightly abrade to create a mechanical key
Ensure the metal is dry before priming

Priming and applying Prolux

Once the metal is clean and dry, apply a suitable metal primer and let it cure according to the manufacturer’s instructions. Prolux is a two-component coating mixed in a 2:1 ratio, and it can be applied as a one-coat system with high coverage. It is available in gloss or satin, so the final appearance can be matched to the surrounding surface.

When a metal-ready coating matters

Prolux is worth considering when metal surfaces sit in high-traffic or exterior settings where abrasion, UV exposure and weathering are part of daily use. Examples include steel trims, metal edging around resin floors, handrails or workshop fixtures. The coating resists yellowing and abrasion better than some standard epoxies, which helps keep metal details looking consistent for longer. It is also CE marked to EN 1504-2, which supports its use in protective coating systems.
