💡 Good to Know
Cork is a natural material, so its properties may vary slightly depending on its origin, grain size, density and manufacturing process. However, all high-quality cork products retain the key characteristics that make cork such a durable, lightweight and versatile material.
🛠 korkie Workshop Tip
Choosing the right cork material is the first step toward a successful project. Our buying guides and expert cork guides will help you compare different cork materials and find the best solution for your application.
What Makes Cork So Special?
Cork has a unique cellular structure. Each individual cork cell is filled with air and surrounded by suberin, a natural substance that gives cork many of its remarkable properties. These characteristics have made cork a highly valued natural material for centuries.
Key Properties at a Glance
✔ Extremely lightweight
✔ Elastic and dimensionally stable
✔ Excellent thermal insulation
✔ Effective sound insulation
✔ Naturally water-resistant
✔ Durable and hard-wearing
✔ Pleasant, warm feel
✔ Sustainable and renewable natural material
Depending on the type of cork product, these properties may vary slightly. For example, cork rolls, cork sheets, agglomerated cork and cork fabric differ in terms of density, flexibility and intended application.

💡 Good to Know
Around 90% of cork's volume consists of tiny air-filled cells. This unique cellular structure is what makes cork exceptionally lightweight, while also providing its excellent thermal insulation and sound insulation properties.
🛠 korkie Workshop Tip
Not every cork product offers the same properties. Cork rolls, cork sheets, agglomerated cork and cork fabric are designed for different applications, such as wall coverings, insulation, furniture, bags and flooring. Choosing the right cork material from the start makes installation easier and ensures the best possible results.

💡 Good to Know
The technical properties of cork can vary slightly depending on the type of cork and the manufacturing process. Cork rolls, cork sheets, agglomerated cork and expanded cork differ in density and are therefore designed for different applications and performance requirements.
🛠 korkie Workshop Tip
When choosing a cork material, don't focus on thickness alone. For many projects, properties such as elasticity, thermal insulation and compressive strength are far more important than the material's thickness. Selecting the right cork for your application will ensure better performance and longer-lasting results.

Processing and laying instructions for roll cork
Compliance with the installation instructions is decisive for the durability as well as for any warranty claims. Mechanical damage to the surface and damage caused by moisture are generally excluded from the warranty. Please check the roll cork for any damage before installation. Differences in colour and structure are natural and therefore no reason for complaint.
Before laying:
Roll cork should be adjusted to the room climate for approx. 24 hours before installation. To do this, simply place the cork with packaging in the room to be laid.
Preparation:
Gluing roll cork is really easy with a little manual skill. Please use the right tools for the work ahead. In addition to the right tools, the preparation of the surface is also very important. It is best to mark the surface beforehand and mask it with masking tape. The roller cork should be glued over the entire surface. The surface must be clean, dust-free, dry and even. Any unevenness, dirt, etc. must be removed, otherwise the result will suffer.
Tools:
Gluing:
The room temperature should be at least 18 ⁰C, the air humidity approx. 50 - 60%. It is advisable to prime the surface before gluing. You can use a simple, commercially available deep primer for this purpose. As soon as this has dried, the cork adhesive can be applied to the substrate with a roller. As soon as you have cut the roll cork to the desired size with a knife, stop rail and angle, you can also apply the adhesive here. Please note that the adhesive is only applied to the desired area! Glue stains must be removed immediately with a damp cloth. Please make sure that the cork adhesive does not come into contact with water in general. The cork adhesive needs a drying time (see processing instructions on the adhesive bucket). As soon as the adhesive has dried completely transparent on the cork and the substrate, you can now start gluing.
Please now roll the cork onto the adhesive surface and press it lightly. A correction is no longer possible after the two adhesive surfaces have touched.
Please make absolutely sure that the adhesive side of the roller cork does not touch, because they stick immediately!
After you have laid out the surface with the cork, please stroke over it once more with the palm of your hand. The pin board can now be used immediately.
We wish you good success and much joy!
