Derform Koala 10 adhesive-backed double-sided underlay

Derform Koala 10 adhesive-backed double-sided underlay is designed for bonding floor coverings, panels and layered assemblies where a secure, continuous adhesive layer is required. The product integrates adhesive on both faces to provide immediate tack to substrates and coverings, reducing the need for separate glue application and speeding up installation and assembly processes. Its construction supports durable adhesion between base surfaces and finishing materials in interior applications.

Advantages

The double-sided adhesive coating ensures instant bonding to both the substrate and the covering, eliminating the time and mess associated with separate adhesives. This underlay simplifies installation workflows by reducing the number of materials and steps needed, while providing consistent adhesion across the bonded area. Designed for indoor use, the product delivers a uniform adhesive layer that helps prevent movement and shifting of mounted panels and floor coverings during and after installation.

Suitable for

• Mounting floor coverings such as vinyl, carpet tiles and thin laminate
• Bonding decorative panels and skirting boards
• Layered assemblies where a continuous adhesive interface is required
• Quick installations or refurbishment projects that benefit from adhesive-backed underlays

Key specifications

• Double-sided adhesive coating for bonding to both substrate and covering
• Underlay material suitable for interior flooring and panel mounting
• Designed for use with thin floor coverings, panels and layered constructions
• Provides immediate tack to reduce installation time

How to use

Prepare the substrate by ensuring it is clean, dry and free of dust, grease or loose particles. Unroll or position the Derform Koala 10 underlay and align it with the area to be bonded. Remove the protective liners from the adhesive faces as directed and press the underlay firmly onto the substrate or covering to achieve full contact. Apply even pressure across the surface to ensure uniform adhesion and avoid trapped air. Trim any excess material for neat edges and allow the assembly to settle as recommended for the chosen covering.

Usage recommendations

For best results, use on smooth, stable interior substrates and avoid application on damp or contaminated surfaces. Test adhesion on a small area if compatibility with a specific covering or substrate is uncertain. Maintain adequate pressure during installation and follow manufacturer handling guidance for storage and temperature ranges to preserve adhesive performance.
