Cork fillers

Cork fillers are compounds made with natural cork, typically available as a paste-like material. They are produced by blending finely ground cork with a binding agent. In most cases, they are applied using a spatula, trowel, or applicator for precise placement.

When are they a good solution? They’re especially useful if you:

• need to seal a small gap or expansion joint (for example along flooring),
• want to fill a cavity or defect (such as inside a shoe sole),
• work with leather and create raised or embossed patterns,
• require spot insulation in areas that are difficult to access,
• operate in industries such as footwear production, construction, or craft design.

When might it not be the right choice? Cork filler should not replace full insulation materials. If your goal is to insulate or soundproof an entire room, cork sheets or expanded cork panels are usually the better option.

If you’re unsure whether this material fits your project, feel free to contact us. It’s always a good idea to confirm before placing an order.

The application largely depends on the product type and the final result you want to achieve.

• Bostik 3070 Sealant Liquid Cork – commonly used for sealing floor expansion gaps, but it can also be applied anywhere cork in a flexible, liquid-like form is required.
• Cork paste / cork filler – often used in shoe manufacturing, decorative elements, and scale modeling.
• Renia 3D Embossing Filler – a specialized paste designed for creating 3D leather embossing. It fills the space beneath the design so the pattern stays raised and keeps its shape over time.

Not sure which product fits your needs? Reach out to us and tell us about your project. Let us know what you're working on and what result you're aiming for — we’ll gladly help you find the best option.

Yes. The material itself remains the same — only the form changes. Instead of cork sheets or rolls, you get a flexible paste that can be applied exactly where it’s needed. It can be pressed into gaps, shaped, and adjusted to fit irregular spaces. This level of precision is difficult to achieve with traditional cork sheets, which is why cork fillers were created in the first place.
