Selleys Direct Stick Sausage Polyurethane Flooring Adhesive | Timber | Australia

A quality timber floor is only as good as the adhesive holding it down. Selleys Direct Stick Sausage is a high-performance, moisture-curing polyurethane adhesive purpose-built for the direct-stick installation of timber overlay flooring across a range of common substrates. Whether you’re laying a new hardwood floor, installing engineered timber overlay, or fixing parquet or composite flooring to concrete or particleboard, this professional-grade formula delivers the bond strength and coverage needed to ensure a stable, long-lasting result.

What sets the Direct Stick Sausage apart is its expanding moisture-curing polyurethane chemistry — as the adhesive cures, it expands to fill minor surface irregularities and maximise the bond footprint between the flooring and substrate. The result is a stronger, more consistent bond across the full installation area, reducing the risk of hollow spots, movement, or squeaking underfoot over time.

Supplied in a practical sausage format for use with a standard sausage gun, it’s a preferred choice among flooring professionals and experienced DIY installers alike. It also offers valuable acoustic benefits, helping to dampen impact noise transmission through timber overlay floors — a critical consideration in apartments, townhouses, and multi-level homes.

Key Highlights

• Excellent Bond Strength — Delivers a powerful, durable bond between timber overlay flooring and a range of common substrates, ensuring a stable, long-lasting floor installation that resists movement, lifting, and delamination over time.
• Expanding Formula Maximises Bond Footprint — The moisture-curing polyurethane formula expands as it cures, filling minor substrate irregularities and increasing the contact area between adhesive and flooring for a more thorough, consistent bond across the entire installation.
• Moisture-Curing Polyurethane Technology — Cures through reaction with ambient moisture, making it reliable and effective across a range of environmental conditions typically encountered on indoor flooring installation sites.
• Trowel-Applied for Professional Coverage — Designed to be applied with a trowel, allowing for consistent, even adhesive coverage across the substrate before laying the flooring — a method preferred by professional flooring installers for optimal results.
• Broad Substrate Compatibility — Suitable for bonding timber overlay, parquet, and composite flooring to a wide range of substrates including timber, MDF, particle board, and concrete — covering the most common flooring installation scenarios.
• Acoustic Benefits for Multi-Level Dwellings — Helps to limit impact noise transmission through timber overlay floors, making it an ideal adhesive choice for apartments, townhouses, and any multi-storey building where sound transfer between levels is a concern.
• Indoor Use Formula — Specifically formulated for indoor flooring applications, ensuring compatibility with the controlled environmental conditions typical of residential and commercial interior spaces.

⚠️ Application & Safety Notes:

• For indoor use only — not suitable for outdoor or submerged applications.
• Ensure substrate is clean, dry, structurally sound, and free from dust, grease, and contaminants before application.
• Apply using a recommended trowel notch size as specified by the flooring manufacturer.
• Allow adequate open time before laying flooring and follow recommended cure times before allowing foot traffic.
• Use in a well-ventilated area — polyurethane adhesives release vapours during curing.
• Wear appropriate PPE including gloves and eye protection during application.
• Keep out of reach of children.
• Uncured adhesive can be removed with solvent — cured adhesive is extremely difficult to remove mechanically.
