Wall Cork Coatings

Cork and its derived decorative materials represent a worthy and original alternative to traditional wall cladding materials in both residential and commercial spaces. The combination of consumer benefits of cork-based coverings is far more appealing than many other familiar and widely used finishing options.

This includes, above all, the unique design of walls covered with cork materials, excellent sound insulation properties (highly relevant, for example, in cafes, restaurants, and other noisy environments), durability, and several other advantageous characteristics of such wall finishes.

This article will discuss the quality and key properties of wall cork coatings, installation methods, maintenance after installation, as well as address common challenges in selecting and using cork materials.

Advantages of Wall Cork Coatings

First, when it comes to cork’s benefits, is its climate adaptability. Walls covered with cork wood effectively retain heat in cold seasons and regulate indoor humidity levels during warm and hot periods. This property is enabled by the unique characteristics of the natural raw material itself.

A second important advantage of these materials is the wide variety of design possibilities they offer. Using wall cork coatings, you can create a diverse atmosphere in any room—from baroque to country style. Cork is especially effective in interiors themed around hunting or medieval knightly life, such as in restaurants.

One of the most attractive features of cork coating is its 100% natural base. The natural material, grown in exotic regions of southern latitudes, contains almost no harmful volatile compounds in its structure. Additionally, no phenolic or formaldehyde-based substances are used in the production of the coating itself. This gives cork a significant advantage over many other wall finishing materials.

Installation of Wall Cork Coatings

Wall cork coatings are manufactured in panels measuring 60 x 30 cm and 3 mm thick. The base of these panels is made from ground cork, while the facing side is made from cork veneer.

Most wall cork coatings fall within a warm color spectrum, making them easy to combine and harmonize with virtually any ceramic tile, wallpaper, most paint and lacquer finishes, mosaic, and more. Cork wall coverings provide good sound insulation and are not a favorable environment for mold, fungi, or other microorganisms to grow.

Installation should begin with assessing the wall surface condition. It must be dry, clean, and flat. Before installation, cork panels are recommended to be left unpacked in the room for at least 2 days to acclimate to the room’s humidity. Skipping this step may result in gaps appearing at panel joints after installation.

Second, when preparing for installation, ensure sufficient surface adhesion. If the wall is painted and smooth, sand it with coarse-grit paper before applying cork. If the wall is flaking (e.g., old or damaged), treat it with deep-penetration primer.

Properly prepared surface for cork installation should have moisture content not exceeding 3%, and room temperature should be maintained around 18°C.

Adhesive choice depends on the application method. It can be standard acrylic adhesive for single-sided application, or contact adhesive for double-sided application. The first method is the simplest and most common, while the second is more complex but more effective.

Before applying tiles, it’s recommended to mark the wall surface. In one corner (usually top-left), draw the perimeter of the first starting panel. Without prior marking, applying cork panels becomes very difficult.

With standard single-sided application, adhesive is applied only to the wall. For double-sided application, adhesive is applied to both the wall and the back of the panels. In the latter case, wait about 20 minutes before placing the panel on the wall.

To improve adhesion quality and ensure full contact across the entire panel surface, a special rubber mallet can be used. However, remember that cork is fragile and delicate—avoid applying excessive force during installation.
