- Clean with harsh solvents or chemicals before the product has fully cured.
Applications in Practice: Trade Scenarios
For Carpenters & Joiners: Bonding Decorative Wall Panels
The Engineering Challenge
Installing heavy decorative MDF or timber panels without leaving visible fastener marks, and without requiring extensive bracing that clutters the worksite and slows down the job.
The System-Based Solution with High Power 609
Apply High Power 609 in vertical, triangular beads approximately 10cm apart. The instant grab will hold the panel in place immediately, allowing for minor adjustments before pressing firmly. The 2mm final bond line provides enough flex to handle building movement.
Best Practice Note
For very heavy or overhead elements, temporary mechanical holding may still be required for the first few hours of the cure. The instant grab is designed to prevent slump and slippage during initial placement.
For Sign Installers: Mounting Metal or PVC Signage
The Engineering Challenge
Achieving a strong, permanent, and invisible bond for aluminium composite or PVC signage onto various facades like brick, concrete, or painted surfaces, especially in external locations exposed to weather.
The System-Based Solution with High Power 609
After cleaning the rear of the sign and the wall surface, apply beads of High Power 609. Its excellent adhesion to metals and plastics, combined with its high strength, ensures a durable bond. The UV resistance guarantees it won't break down over time, even in direct sunlight.
Best Practice Note
For powder-coated metals or PVC, it's best practice to slightly roughen the surface with a fine abrasive pad and clean with Adheseal 50A Surface Prep to ensure optimal adhesion and long-term performance.
For Caravan & Vehicle Builders: Elastic Structural Bonding
The Engineering Challenge
Bonding panels, profiles, and fixtures in vehicles, caravans, or marine craft where the bond will be subject to constant vibration, shock, and thermal expansion and contraction.
The System-Based Solution with High Power 609
High Power 609 is ideal for this work. Its permanent elasticity (200% elongation) absorbs dynamic stresses that would cause rigid epoxies or brittle adhesives to fail. It bonds tenaciously to the common substrates used in these industries, such as aluminium, fibreglass, and timber.
Best Practice Note
Ensure a minimum bond line of 2-3mm is maintained. This thickness is critical for the adhesive to effectively dissipate stress and maintain its elastomeric properties over the vehicle's lifespan.

Frequently Asked Questions
How strong is the 'instant grab' of High Power 609 in practice?
The instant grab is exceptionally effective. For most vertical applications like wall panels, splashbacks, or decorative elements, Adheseal High Power 609 will hold the item in place immediately without slipping. This means you can often work without clamps or braces, saving significant time. For very heavy or overhead items, some temporary support is still a best practice until the adhesive develops its full cure strength.
Can I use Adheseal High Power 609 on damp timber or concrete?
Yes, one of the key advantages of High Power 609 is its ability to adhere to slightly moist or damp substrates. It is perfect for job sites where conditions are not perfectly dry. However, it is important to ensure the surface is free of standing or pooling water. The substrate should be damp, not saturated, for a reliable, long-term bond.
What is the cure time for High Power 609 before it reaches full strength?
Adheseal High Power 609 skins over in approximately 10-30 minutes, preventing dust contamination. It cures at a rate of about 2mm per 24 hours at 23°C and 50% humidity. Cure time can be faster in warmer, more humid conditions and slower in cold, dry weather. While the instant grab provides immediate hold, you should allow for the full cure before subjecting the bond to heavy loads or significant stress.
Do I need to use a primer with this adhesive?
For most common building materials, High Power 609 achieves excellent adhesion without a primer. However, for critical applications, highly stressed joints, or maximum long-term performance on non-porous surfaces like PVC and powder-coated metals, using Adheseal 50A Surface Prep is recommended. For porous substrates like raw concrete or brick, Everflex Supaprime can be used to ensure optimal adhesion.
Is High Power 609 suitable for exterior use in Australia?
Absolutely. It is specifically formulated with exceptional weather and UV resistance, making it ideal for exterior applications. It remains elastic and stable across a wide service temperature range of -40°C to +100°C, ensuring it performs reliably through hot summers and cooler winters without becoming brittle or losing its bond strength. It's perfect for external signage, cladding, and fixtures.

Applying Adheseal High Power 609: Professional Application Protocol
-
Surface Preparation
A successful bond starts with a properly prepared surface. The substrate must be clean, dry or slightly damp, structurally sound, and completely free of contaminants.
For Non-Porous Surfaces (Metals, Plastics, Painted)
Use a two-wipe process. First, wipe the surface with a clean cloth soaked in a suitable cleaner like 100% White Spirits to remove oils and grease. Immediately wipe dry with a separate, clean cloth before the solvent evaporates.
For Porous Surfaces (Concrete, Masonry, Raw Timber)
Mechanically remove all loose and friable material using a stiff brush or grinder. Ensure all dust is removed by vacuum or air blower. New concrete must be cured for a minimum of 28 days.
Pro Tip: Never assume a surface is clean. A quick wipe-down can be the difference between a temporary fix and a permanent, professional bond. -
Adhesive Application
For maximum grab and final bond strength, the application technique is critical. Use a quality caulking gun for consistent pressure and flow.
The Triangular Bead Method
Cut the nozzle to create a 'V' shape. Hold the caulking gun at a 90° angle to the substrate and apply the adhesive in vertical beads. This creates a triangular bead that is twice as high as it is wide, ensuring it compresses and spreads correctly when the item is pressed into place.
Bead Spacing: For panels and large items, apply beads 5 to 10cm apart, depending on the weight of the item. -
Bonding & Final Assembly
Once the adhesive is applied, you have a short window to complete the bond while the surface is still wet and tacky.
Final Placement
Firmly press the item to be bonded onto the adhesive beads. The instant grab will hold it in place. Apply even pressure across the entire surface to ensure the adhesive spreads and achieves full contact, creating a final bond line of at least 2mm.
Pro Tip: Do not disturb the bond during the initial cure. While it holds instantly, full strength and elasticity develop over time. Clean up any excess uncured adhesive immediately with white spirit.
Limitations & Safety
Product Limitations
Not for use in totally confined spaces. The product requires atmospheric humidity to cure properly.

Adheseal High Power 609 Substrate Guide
Timber, MDF & Particleboard
Surface Preparation
Ensure timber is structurally sound, clean, and free of dust, oils, or any loose material. Surface can be slightly damp but must not have pooling water. For painted or sealed wood, ensure the coating is well-adhered.
Primer Requirements
No primer typically required
Excellent adhesion is achieved on raw and coated timber without a primer. For critical structural applications, a compatibility test is always recommended.
Metals (Aluminium, Steel, Powder-Coat)
Surface Preparation
Degrease the surface using a two-wipe process with a suitable solvent like 100% White Spirits. For powder-coated or anodised aluminium, lightly abrade the surface with a fine abrasive pad to create a mechanical key.
Primer Requirements
Primer recommended for optimal adhesion
For maximum bond strength and long-term durability, especially in exterior or high-stress situations, pre-treat the prepared surface with Adheseal 50A Surface Prep.
Adheseal 50A Surface PrepConcrete, Stone & Masonry
Surface Preparation
Surfaces must be free of dust, laitance, and curing compounds. New concrete must be cured for at least 28 days. Wire brush or grind the surface to remove any loose or friable material.
