Adheseal Multi-Grip is a high-solids acrylic construction adhesive engineered for heavy-duty bonding of timber, plasterboard, and FC sheeting to vertical studs and overhead joists. Featuring a non-sag paste consistency and very high initial grab, it provides immediate positioning security for cornices and wall linings without extensive mechanical bracing.
This moisture-curing formula is AS 2753 and AS 2329 compliant, specifically designed to eliminate floor squeaks in tongue-and-groove joints while remaining flexible enough to absorb structural movement. For optimal results, ensure the ambient temperature is between 5°C and 35°C, and avoid use on saturated surfaces or for strip flooring and parquetry installations to prevent bond failure.
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.

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.
