KEIM Lignosil system: Silicate paints for wood

Innovative wood paints and colourwashes for sustainable buildings.

Wood protection: KEIM Lignosil, the first silicate paint for wooden surfaces

For more than twenty years, the developers at KEIM worked on transferring the successful model of silicate paint to wood in the framework of a research project, supported by well-known institutes. In 2013, KEIM Lignosil was launched on the market as the first mineral composite coating to protect wood from the influence of the weather. KEIM has thus engineered a durable, economical and aesthetic system for the substrate wood.  Developing a silicate coating for the organic substrate wood constituted a pioneering advance in the quality of wood coating. The KEIM Lignosil System consists of paints and colourwashes for both exterior and interior use, from opaque to semi-transparent. The velvet matte appearance of the wood paint Lignosil-Color sets new standards in wood aesthetics, wood protection and wood architecture, and underlines the character of wood.

Cradle to Cradle Certifiedยฎ

The Cradle to Cradle Certifiedยฎ certificate sees materials as substances that are made available to new processes after use. All substances contained in the products must therefore be assessed scientifically for circularity.

KEIM Lignosil-Verano and KEIM Lignosil-Inco received the Cradle to Cradle Certifiedยฎ certificate in silver.

In the areas of material health, water management and social fairness, the products achieved gold certification. The overall certification result is based on the lowest rated criterion.

With our certified circular products and the use of harmless materials, we make a significant contribution to sustainable building.

Cradle to Cradle

The Cradle to Cradle design concept is the world's most advanced standard for designing and manufacturing products that enable a healthy, equitable and sustainable future. Cradle to Cradle is based on nature's material cycles, in which all substances are the basis and nutrients for something new.


KEIM Lignosil-Color โ€“ the perfect wood paint for exterior use

Conventional coatings for wood โ€“ wood paints and wood protection lacquers based on linseed oils, alkyd resin, acrylates and other plastics โ€“ have a limited service life of approximately 3 to 7 years,  depending on their quality and the stresses involved. The lack of UV-resistance of the these wood treatments, together with premature decomposition of the binder, causes cracks, spalling and differences in colour in wood protection. In turn, this leads to high maintenance costs, short renovation cycles and elaborate preparatory work before applying a new coat of paint. 
This does not apply to the innovative, silicate wood paint for exterior use: KEIM Lignosil-Color which overcomes these issues.

The advantages of the wood paint Lignosil-Color

  • Outstanding moisture protection
  • UV-stable and absolutely lightfast
  • Unrivalled durability and extremely weatherproof for exterior use
  • Velvety matt surface look and easy to renovate
  • Tested as per DIN EN 927
  • External supervision by WKI Braunschweig (Fraunhofer Institute for Wood Research)

The key advantages of the use of a silicate wood paint are further enhanced by the low material and labour costs involved in renovating wood, making KEIM Lignosil-Color unbeatable in technical and economic respects. Due to its special ageing behaviour, which is typical for silicates, the coating structure of KEIM Lignosil-Color is extremely durable and ensures that Lignosil surfaces do not usually need to be sanded before being renovated. Thorough cleaning of the surface is the only preparation needed, so that renewed priming with KEIM Lignosil-Base/-W is not necessary when redecorating.

Controlled greying with the wood colourwash Lignosil-Verano

Those who prefer a natural look and greying of exterior wood surfaces need look no further than KEIM Lignosil-Verano. By deliberately waiving the protective function, as is usually desired for wood coatings, the coat of KEIM Lignosil-Verano gradually turns into a natural grey colour as time passes. KEIM Lignosil-Verano is available in several classic and metallic colour shades.

No additional coats need to be applied โ€“ the desired look of an elegant, greyed wood facade develops by itself as a result of our paint, without the need for any further effort or action.


Optimum room climate with Lignosil-Inco

KEIM Lignosil-Inco is a silicate interior wood paint for opaque and semi-transparent coloured coatings and for designing wood and wood-composite materials indoors. Lignosil-Inco maintains the natural hygroscopic properties of the wood and thus ensures a natural, odourless and pleasant indoor climate. KEIM Lignosil-Inco is available in white and in all colours shades of the KEIM Exclusiv and KEIM Avantgarde colour charts. Other colour shades are available on request.
