More about this product

KEIM Lignosil®-Verano is a silicate greying glaze for non-dimensionally stable and limited dimensionally stable wooden building components outside. It simulates a greyed, patinated surface as it occurs on natural wood after years of weathering. KEIM Lignosil®-Verano is subject to a natural aging process and equalizes in this way the visual differences which can appear by uneven weathering of exposed and protected surfaces of uncoated wood.

Natural Finish or Coating?

Greyed wooden facades have a particular charm. But it may take decades until the wood shows an evenly grey patina like a mountain hut in the Alps. Untreated wooden facades change their color and texture under environmental influences. It is difficult to predict such changes because many factors influence the different facade surfaces of the building exposed to the weather in various ways. Wood type, direction, location, rainfall, air purity, and the constructional prerequisites decide on optical development.

A Question of Aesthetics

The attitude of architects and builders hereto is controversial like the phenomenon itself: Letting nature take its course or controlling the development with a coating. KEIM Lignosil®-Verano, a silicate-based finish, produces a naturally beautiful, silver-grey patinated wood appearance from the first application on. With a conscious decision to waive the protective function, a coating with KEIM Lignosil®-Verano changes over time more and more into natural greying. Repainting is not necessary. The result will be the desired look of an elegant, greyed wood façade without further maintenance efforts.


KEIM-Lignosil®-Verano is biocide- and solvent-free and guarantees a natural, mineral matt, color-stable appearance. The treated surfaces remain open to diffusion. Lignosil®-Verano is a particularly economical and sustainable system thanks to fast drying and very easy application.
