When you bond timber or particle board in flooring and wall systems, you need an adhesive that moves with the material. Adheseal Multi-Tack provides the essential flexibility. It bonds securely while accommodating natural movement, eliminating floor squeaks and preventing sub-floor warping. Get a permanently flexible, high-strength bond that keeps your surfaces stable.
Sub-floor and wall systems face constant movement as timber dries and shifts. Rigid adhesives fail under this stress, leading to squeaks, warping, and callbacks. Adheseal Multi-Tack was formulated to counteract these issues. It creates a robust bond that remains permanently flexible, absorbing movement rather than fighting it. This ensures your installations stay silent, stable, and durable over time, from joists and studs to cornices and wall sheeting.
Flexibility is critical for this adhesive. With an elongation at break of 434% and a Shore A Hardness of 33, Adheseal Multi-Tack maintains a compliant, resilient bond. This high elongation ensures the adhesive stretches and recovers under timber movement, preventing cracks and bond failures. A low tensile strength of 0.471 N/mm² reinforces its purpose: accommodating stress, not resisting it rigidly. It complies with AS:2753 for plasterboard and AS:2329 for other wallboards, giving you specification confidence for internal lining systems.
Prepare surfaces by ensuring they are clean, dry, and free of dirt. For warped timber, sand flush for optimal contact. Apply a 6-10mm bead of Multi-Tack to joists, studs, or panel grooves. For butt joints, use two beads 25mm apart. Position the panel with minimal movement. The adhesive provides a 30-minute skin time at 25°C and 50% RH, offering a workable window for placement. Uncured adhesive and tools clean up easily with water.
Safety Note: While not classified as dangerous for transport, this product is a hazardous chemical. Wear protective gloves and safety glasses. If skin irritation or sensitisation occurs, consult a doctor. Avoid inhaling vapours, which may cause allergy or asthma symptoms in sensitive individuals.
Yes, Multi-Tack is effective for eliminating floor squeaks. Apply adhesive to the groove of one flooring sheet before positioning the next to improve rigidity and prevent movement.
Multi-Tack adheres to damp surfaces but is not suitable for areas saturated with water. It is not for continuous water immersion applications.
This acrylic adhesive provides a strong bond and offers permanent flexibility, allowing for movement within flooring and wall systems. It is also shock resistant and complies with AS:2753 and AS:2329 for wallboard fixing.
Yes, Adheseal Multi-Tack is paintable once cured. Clean up any excess adhesive with water before it dries to ensure a smooth finish.
| Application | Key benefit | Primary trades |
|---|---|---|
| Sub-floor construction (timber, particle board) | Prevents squeaking and assists in reducing warping as timber dries. Delivers permanent flexibility for movement. | Carpenters, Builders, Flooring Installers |
| Bonding timber to studs and joists | Provides a strong and permanently flexible bond. Reduces reliance on fasteners alone. | Carpenters, Framers, Builders |
| Fixing plasterboard and other wallboards | Complies with AS:2753 and AS:2329 for reliable fixing. Offers non-sag consistency for overhead work. | Plasterers, Builders |
| Installing cornices and mouldings | Excellent adhesion for internal and external mouldings. Non-sag formulation prevents slump, and it is paintable. | Finish Carpenters, Plasterers, Painters |
| Bonding polystyrene foam components | Securely bonds polystyrene without damaging the material. Provides shock resistance to the assembly. | Insulation Installers, Builders, Signmakers |
Ensure substrates are clean, dry, and free from oil, dust, or wax. Mechanically prepare smooth concrete or dusty boards for improved bond.
Use a notched trowel, roller, or brush depending on surface size and adhesive spread required.
Spread a consistent layer of Multi-Tack onto the surface. Apply only as much area as can be covered within the tack time.
Allow 5–15 minutes for tack development before placing flooring or panels, depending on temperature and humidity.
Position materials carefully and press firmly across the surface to ensure full contact and bond development.
Clean up excess adhesive and tools with water before the product cures. Once dry, mechanical removal is required.
Warning: This material is hazardous according to Safe Work Australia GHS 7 criteria. It is a Schedule 5 Poison (Caution).
Wear protective gloves, apron, and safety glasses. Nitrile rubber gloves are suitable for intermittent contact. Always wash hands before eating, drinking, or smoking.
Use in well-ventilated areas. Ensure ventilation is adequate to maintain air concentrations below exposure standards. Avoid generating and inhaling dusts, and consider a dust mask if necessary.
Store in a cool, dry, well-ventilated place between 5°C and 35°C, away from direct sunlight, foodstuffs, incompatible materials, heat, and ignition sources. Keep containers upright and closed when not in use. Dispose of waste in accordance with local regulations, preventing release into groundwater or waterways.
Proper surface preparation is crucial for bond performance and preventing callbacks. This guide covers common substrates for Adheseal Multi-Tack.
Surface prep: Ensure surfaces are clean, dry, and free of dirt, dust, or grease. Sand any warped or twisted timber to achieve flush surfaces before application. The adhesive will bond to damp timber, but not saturated material.
Primer: Not required. Multi-Tack is formulated for direct adhesion to timber and timber-derived substrates.
Surface prep: Surfaces must be clean, dry, and free from loose material, dust, oil, and other contaminants. For concrete, ensure it is fully cured. Lightly abrade metal surfaces for optimal adhesion if necessary. The adhesive will bond to damp concrete or FC sheeting, but not saturated material.
Primer: Not required. Multi-Tack adheres directly to these common construction materials.
Surface prep: Ensure surfaces are clean, dry, and free of release agents or dust. Multi-Tack is suitable for bonding polystyrene without attacking the foam.
Primer: Not required.
