When you need to secure parquet, solid, or engineered timber flooring to any subfloor, indoors or out, you need a bond that flexes with the timber. MS-608 delivers that combination: high strength with permanent elasticity. It holds the floor down while dampening sound, handling movement, and resisting moisture.

Why this product exists

This adhesive solves the challenge of bonding diverse timber flooring to varied subfloors, without compromising on flexibility or acoustic performance. We formulated MS-608 as an odourless, one-part hybrid silyl modified polyether adhesive. It offers high mechanical bond strength, permanent elasticity, and good sound dampening. This ensures a stable, quiet floor that withstands both internal and external environmental changes, without the need for primers on damp surfaces.

The numbers that matter

  • 0.90 mPa Lap Shear Strength (Wood to Wood): This is your guarantee of a secure bond. The adhesive forms a strong connection, preventing uplift or movement, even with the natural expansion and contraction of timber.
  • 800% Elongation at Break: This extreme flexibility allows the adhesive to absorb significant timber movement. It minimises stress on the floorboards, preventing cupping, gapping, or adhesive failure due to seasonal changes or subfloor movement.
  • Shore A Hardness of 40: This indicates a firm yet elastic cure. The adhesive provides sufficient structural support for the flooring while maintaining its flexibility for sound dampening and stress relief.
  • Service Temperature -40°C to 100°C: This wide range ensures performance in extreme climates. Whether for heated indoor spaces or exposed outdoor decking, the bond remains stable without degrading or losing flexibility.

What it's like to use

Prepare surfaces by ensuring they are clean, dry, and free from contaminants. Apply MS-608 with a trowel, spreading only enough adhesive that you can lay flooring within the 20-30 minute open time. Once applied, slide the parquet into position and tap down firmly. The adhesive skins in approximately 30 minutes. It achieves a 10 mm cure depth in 7 days, though cooler, drier conditions may extend this. For clean-up, use mineral spirit or a cleaning solvent before the adhesive cures. Once cured, removal requires mechanical methods. You can paint MS-608 with water-based paints, but always test first. Be aware that the adhesive's movement capability is greater than most paint films; movement in the joint may cause paint cracking.

Where this product excels

  • Timber Flooring Installations: Securely bond finger block, solid wood, engineered wood, and plywood flooring. Its high strength and flexibility accommodate the natural characteristics of timber.
  • Acoustic Flooring Systems: The elastic cure and good sound dampening quality contribute to quieter spaces, making it suitable for residential, commercial, or educational settings where noise reduction is critical.
  • Indoor & Outdoor Applications: From internal parquetry to external timber decking and balcony cladding, MS-608 handles UV exposure, weather changes, and temperature cycling without debonding.
  • Installations Over Damp Subfloors: Its moisture resistance and ability to be applied on damp surfaces reduce delays and simplify subfloor preparation, particularly for concrete slabs.

How it fits in a real system

MS-608 serves as the critical bonding layer between timber flooring and the subfloor. It is the primary adhesive, applied after subfloor preparation. Its performance is directly tied to a clean, structurally sound subfloor, ensuring optimal adhesion and long-term durability for the flooring system.

Choose this when

  • You are bonding solid timber, engineered wood, or parquetry.
  • The project demands both high bond strength and permanent flexibility to prevent flooring failure.
  • Sound dampening is a required performance characteristic for the finished floor.
  • The flooring will be installed in an environment where an odourless, solvent-free adhesive is preferred or mandated.
  • The application covers both internal and external timber flooring.

Don't use this when

  • Not for: Bonding to PE, PP, PTFE, plastics containing softeners, or bituminous substrates. These materials are incompatible and will not form a reliable bond.
  • Not for: Applications requiring structural glazing. This product is formulated for flooring, not for glass bonding in structural assemblies.
  • Not for: Totally confined spaces where atmospheric humidity is absent, as moisture is essential for proper curing.
  • Not for: Continuous underwater applications or heavy trafficable surfaces/joints, as these conditions exceed its design limits.
  • Not for: Direct food contact or exposure to aggressive solvents and chemicals, which can compromise its performance and integrity.
