Multi-Tack Adhesive is a high-performance acrylic construction adhesive designed for professional drywall and plasterboard installers working on timber and metal framing. This non-sag formula eliminates common issues like structural nail pops and floor squeaks by maintaining a permanently flexible bond that absorbs movement from timber shrinkage and thermal expansion.
It fully complies with AS: 2753 and AS: 2329 standards, ensuring reliable results for interior wallboard, decorative cornices, and exterior F.C. sheeting systems.
Frequently Asked Questions
What substrates can Multi-Tack be applied to?
Multi-Tack is compatible with concrete, timber, vinyl, acoustic panel backings, MDF, particleboard, and primed surfaces.
Can I use Multi-Tack for wall panels or only flooring?
Yes. Multi-Tack can be used for vertical installations such as acoustic panels or MDF wall linings, provided weight is supported during curing.
Is Multi-Tack safe for indoor environments like schools and hospitals?
Yes. It is water-based, low-VOC, and non-toxic once cured – ideal for enclosed or sensitive areas.
How should I apply Multi-Tack?
Use a notched trowel, brush, or roller. Allow tack-off before bonding for best adhesion on flooring and panel installations.
How long does it take to cure?
Initial grab is immediate; full bond strength is typically achieved within 24–48 hours depending on material and humidity.

How to Apply Multi-Tack: Step-by-Step
-
1. Prepare the Surface
Ensure substrates are clean, dry, and free from oil, dust, or wax. Mechanically prepare smooth concrete or dusty boards for improved bond.
-
2. Choose Application Tool
Use a notched trowel, roller, or brush depending on surface size and adhesive spread required.
-
3. Apply Adhesive
Spread a consistent layer of Multi-Tack onto the surface. Apply only as much area as can be covered within the tack time.
-
4. Wait for Tack-Off
Allow 5–15 minutes for tack development before placing flooring or panels, depending on temperature and humidity.
-
5. Bond & Press Down
Position materials carefully and press firmly across the surface to ensure full contact and bond development.
-
6. Clean Tools & Surfaces
Clean up excess adhesive and tools with water before the product cures. Once dry, mechanical removal is required.
