Surface refinement - a process with a mythical character

Refining surfaces with precious metals (bronze, gold, silver, ...)

Refining different surfaces, amongst other things, with precious metals such as gold, silver etc., has its roots in the long tradition of church restoration. Early on, the masters of sacred works of art recognised the significance of refinement for the visible grandeur of church spaces. Modern refinement methods such as or hand-made metal coatings are based on this broad foundation of art history. Many different metal surfaces can be worked with: Sanded and polished bronze, stained bronze, sanded gold, polished gold, sanded and polished brass, and many more.

Hand-made genuine metals coatings - an obvious form of added value

Today, you can find the principle of refinement in a wide variety of different business sectors: in the textile and printing industry, in agriculture, and botany. Food, stones and even digital datasets are subject to refinement as well, and thus an increase in value. The name RGO (coating resin surfaces) stands for refining differing surfaces. The metallic look and feel, the utterly seamless coating and the outstanding adhesive properties are an obvious form of added value.   

Liquid metal coating for architecture, space and residential design

Only metallic coatings are used in the RGO process: Copper, bronze, brass, aluminium, iron, stainless steel and different mixed alloys are applied in several layers - depending on the quality of and requirement for the respective basecoat. Plastic, wood, iron and bonded panels are suitable for refinement. Even mineral surfaces such as granite and marble, terracotta and red sandstone, concrete and plaster are great carrier materials for coating resin surfaces.

These liquid metal and genuine metal coatings can be used seamlessly for many different shapes and elements, and are therefore suited to architecture as well as to interior finishing and residential design.

The highest quality metallic surface coating

The Lehner Paint Shop in Fürstenzell in Lower Bavaria offers genuine metal coatings, liquid metal coatings, as well as refinement of surfaces with a metallic look and feel to the highest specification. The renowned business close to the three river town of Passau has refined and advanced RGO application to perfection with numerous in-house developments. You could say it’s refined refinement! The innovative finishing method for surface refinement with metal (metal skin) impresses thanks to its total uniformity and sparkle.

Relief-granulated surfaces by Lehner – detailed and precise

Lehner goes above and beyond: refined surfaces look like a carbon copy of the original.

Here’s a common example from real life: A bare iron door is attached to a wooden doorframe for structural reasons. The customer wanted the same look as the bare iron door and the wooden doorframe. In addition, the wooden frame should ‘age’, this means rust patina should emerge on the frame over time - like on the iron door. Lehner’s sophisticated process technology makes this possible! And there’s much more: Bronze surfaces go green-tinged and brownish-coloured like the original. Aluminium applications go dark grey over time, copper coatings go dark brown. In the case of iron surfaces, just a rusty-coloured patina appears.

The secret of first-class boundary layer quality and structure is in the professional layering method and in appropriate pre-treatment. With this precise method, Lehner can, for instance, adapt refined workpieces to anodised window frames in a way that looks beautiful. A flawless genuine metal skin of the highest quality.
