For high-load installations, vertical panels, and joints subject to constant vibration or movement, High Power 609 Instant Grab Adhesive provides a 1-second immediate grab that reduces the need for temporary mechanical supports. This single-part MS hybrid polymer cures via atmospheric moisture, forming an elastic bond that adheres to damp construction surfaces and common building substrates without corroding concrete or galvanised metals.
High Power 609 combines a rapid initial wet grab with high elastic recovery. By curing into a flexible elastomer, it absorbs mechanical shock, thermal expansion, and structural vibrations in transport, marine, and construction assemblies. The formulation is free of isocyanates and silicones, allowing it to be painted over with water-based coatings once cured. It maintains a stable, non-sagging profile during application and resists prolonged weather and UV exposure in both internal and external environments.
This adhesive bonds a wide selection of materials across the building, sign, transport, and marine industries, including:
All surfaces must be structurally sound, clean, and free of dust, grease, curing compounds, or standing surface water. Concrete must cure for a minimum of 28 days before application.
For non-porous substrates such as aluminium, waterproof membranes, stainless steel, and glazed tiles, slightly roughen the surface with a fine abrasive pad. Clean and pre-treat the joint with Adheseal 50A surface prep using a clean cloth, allowing between 30 minutes and 2 hours drying time before applying the adhesive. For porous surfaces like concrete, mortar, and brick, prime the joint using Everflex Supaprime applied by brush, adhering to the same 30-minute to 2-hour window.
Apply the adhesive at temperatures between 5°C and 40°C using a manual, pneumatic, or cordless caulking gun. Cut the triangular nozzle to ensure the dispensed bead stands twice as high as its width (in a triangular profile). Apply parallel beads spaced 5cm to 10cm apart, depending on the weight of the panel. Press the components together while the adhesive is still wet, ensuring a minimum wet adhesive thickness of 2mm is maintained to allow the elastic properties to function correctly. Clean wet tools and spills immediately with white spirit; cured adhesive must be removed mechanically.
Yes, High Power 609 is designed for instant grab applications. Wet strength is rated up to 400kg/m², which helps reduce temporary fixing on many panel jobs. Heavy vertical elements may still require mechanical support until cure develops.
Yes, it is suitable for internal and external applications. The cured adhesive remains elastic and has documented UV and weather resistance. Correct surface preparation still matters for long-term external performance.
Yes, it adheres to slightly moist substrates. The surface must still be free from standing water, oils, and contaminants that interfere with adhesion. Concrete should cure for at least 28 days before application.
No, it is not suitable for structural glazing applications. The TDS specifically directs structural glazing work to glazing silicone systems such as N-80 or N-60. Using the wrong product risks bond failure and compliance issues.
Skin formation starts in approximately 10 to 30 minutes. Cure rate is around 2mm per 24 hours at 25°C and 50% humidity. Cooler temperatures and non-porous substrates will slow curing.
| Application | Key benefit | Primary trades |
|---|---|---|
| Wall panel and profile bonding | Instant grab reduces temporary support and speeds installation sequencing | Shopfitters, carpenters, installers |
| Sign and display assembly | Elastic bond handles vibration and mixed-material movement | Sign installers, fabricators |
| Caravan and trailer fit-outs | Flexible cured bond withstands transport vibration and movement | Vehicle builders, caravan manufacturers |
| Timber and MDF component fixing | High initial tack helps hold trims and profiles in place during cure | Cabinetmakers, joiners |
| External façade bonding | UV and weather resistance support exposed applications | Facade installers, builders |
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.
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.
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.
For maximum grab and final bond strength, the application technique is critical. Use a quality caulking gun for consistent pressure and flow.
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.
Once the adhesive is applied, you have a short window to complete the bond while the surface is still wet and tacky.
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.
Wear nitrile rubber gloves and safety glasses during handling and application. Assess site-specific hazards for any additional PPE requirements.
Natural ventilation is adequate under normal use. Avoid use in totally closed rooms where atmospheric humidity for curing is restricted.
Store in a cool, dry, well-ventilated place, out of direct sunlight, at temperatures between 5°C to 30°C. Keep containers closed and upright. Shelf life is 9 months from the date of manufacture. Dispose of according to state or local regulations.
This guide covers the surface preparation and priming requirements that affect long-term adhesion performance.
Surface prep: Lightly roughen aluminium, stainless steel, PVC, glazed tiles, waterproof membranes, galvanised steel, and powder-coated metals using a fine abrasive pad. Clean using the two-wipe process with clean cloths and suitable solvent preparation.
Primer: Optional. Adheseal 50A surface prep is recommended for critical high-performance applications and exposed joints. Allow 30 minutes to 2 hours before applying adhesive.
Surface prep: Concrete, cement render, aerated concrete, mortar, and brick must be clean, stable, and cured for at least 28 days before application.
Primer: Required for optimum adhesion. Use Everflex Supaprime applied by brush and allow 30 minutes to 2 hours before adhesive application.
