Applications

  • Suitable for applications where lightweight core is used

Mix Ratio

  • 2:1 (By volume)

Introduction

Spabond 568 is a low density adhesive, with a simple 2:1 by volume mix ratio which is designed for bonding a wide range of core materials. The product is uniquely filled and can be applied in thicknesses of up to 6mm at 20°C on vertical surfaces without the risk of drainage.

Resin and hardener are both colour coded to ensure consistency of the mix. The resin is light green and the hardener pale brown leading to a neutral grey colour when fully mixed.

With the fillers used in its formulation, Spabond 568 is easy to sand and can be used for strip planking with wood or foam strips.
