Adheseal Multi-Grip: A Technical Overview
Multi-Grip is a high-performance, acrylic-based construction adhesive designed for trades needing high initial grab with fast install turnaround. It's moisture-curing, paintable, flexible, and easy to apply to timber, F.C. sheeting, metal, concrete, and foam — even on damp surfaces. Its non-sag paste consistency and anti-squeak formulation make it ideal for both subfloor and overhead work. Complies with AS 2753 and AS 2329.
Core Features & Specifications
- Water-based acrylic with over 70% solids content
- Very high initial grab for vertical installs and reduced clamping
- Non-sag formula for overhead and wall sheet fixing
- Flexible bond resists cracking or squeaking in floors
- Paintable and low VOC (47g/L)
- 600ml sausage pack compatible with sausage guns
The Adheseal Multi-Grip Advantage
- No slip install — get more done in less time
- Damp-surface compatibility means fewer weather delays
- Clean up with water before cure — ideal for indoor fitout teams
- Resists floor squeaks and joint fatigue long-term
Best Practices: Do's & Don'ts
Do
- Use 6–10mm beads for most timber-to-stud or joist applications
- Apply adhesive to T&G grooves to prevent squeaks
- Install wall sheeting with minimal repositioning over wet adhesive
Don't
- Don’t use with strip flooring or parquetry
- Avoid applying to saturated surfaces
- Don’t disturb bond after initial placement — fast grab sets quickly
Applications in Practice: Trade Scenarios
For Builders (On-Site Installer): Subfloor Paneling
The Engineering Challenge
Squeaks and joint movement in floors are common where poor bonding or shrinkage occurs. Rework is costly once sheeting is nailed down.
The System-Based Solution with Adheseal Multi-Grip
Apply 6mm beads to each joist and an additional bead in the groove of T&G flooring. This improves contact and eliminates squeak points as the timber settles.
Best Practice Note
Wipe off squeezed-out adhesive before it cures. Follow floor manufacturer fixing specs for nails or screws.
For Fixout Carpenters: Cornice & Moulding Install
The Engineering Challenge
Fixing internal mouldings requires strong initial hold without nails or supports, especially overhead.
The System-Based Solution with Adheseal Multi-Grip
Apply a continuous bead along the moulding back and press into place firmly. The high tack prevents sagging even before full cure.
Best Practice Note
Use a support brace for heavy cornices until cure if ambient humidity is low. Clean off any smears with damp cloth.

Frequently Asked Questions About Adheseal Multi-Grip
Q: Can Multi-Grip be used to bond wet timber in subfloor construction?
A: Multi-Grip is suitable for damp surfaces, but not for saturated timber. Ensure timber is surface dry to achieve optimal bond strength and prevent curing issues.
Q: Will this adhesive stop my T&G floor from squeaking?
A: Yes. Apply a bead to the groove before placement. This improves rigidity and eliminates friction, a common cause of floor squeaks during seasonal movement.
Q: How long before I can walk on bonded surfaces?
A: While it skins in 25 minutes, full bond strength develops over time. Avoid heavy traffic or stress for 24 hours to allow proper cure, especially in flooring applications.
Q: Is it suitable for overhead cornice installation?
A: Absolutely. Multi-Grip’s high initial grab and non-sag formula makes it ideal for securing cornices, mouldings, and trims without support fixtures.
Applications & Benefits
| Application / Use Case | Key Benefit | Primary Trades |
|---|---|---|
| Timber to Studs & Joists | Strong hold without nails or screws | Builders, Carpenters |
| Subfloor Squeak Elimination | Prevents movement and sound in T&G joints | Builders, Flooring Installers |
| Cornice & Moulding Installation | No drip or slump for overhead bonding | Plasterers, Decorators |
| Polystyrene Foam Fixing | Secure bond without melting foam | Insulation Installers |
Applying Adheseal Multi-Grip: Protocols & Best Practices
General Application Steps:- Preparation: Ensure the substrate is clean, dry, and prepared as per the Adhesion & Preparation Guide. Mask adjacent surfaces for a clean finish.
- Application: Apply a 6–10mm bead directly to joists, studs, or substrate. For panels that butt together, use two beads 25mm apart. Press panels into place firmly.
- Tooling & Finishing: Tool within 10 minutes to achieve full contact. Remove excess before skin formation.
- Curing: Avoid movement and water exposure during the first 24 hours. Full strength develops as moisture dissipates.
Limitations & Safety
