Gorilla Heavy Duty Grab Adhesive is designed for individuals tackling construction, DIY, or repair projects who need a strong, fast-curing, and waterproof bonding solution. Its key benefit is providing instant, heavy-duty adhesion without the need for mechanical fasteners like nails or screws, though proper surface preparation is crucial for optimal performance. This 3-pack of 290ml tubes offers a substantial supply for multiple or larger jobs, delivering durable results on a variety of materials.

Full cure typically takes 24-72 hours, depending on bead size, temperature, and humidity. However, it achieves a strong initial grab within minutes.
It bonds to some plastics, but not all. It is recommended to test on a small, inconspicuous area first to ensure compatibility, as it may not adhere well to certain types of plastic like polyethylene or polypropylene.
Yes, once fully cured, the adhesive can be painted over.
While it provides heavy-duty strength, it is generally recommended for non-load-bearing applications or as a supplementary fastener. For critical structural joints, consult engineering specifications.
After use, leave a small amount of adhesive in the nozzle tip. Clean the nozzle tip and screw the cap on tightly. Store upright in a cool, dry place. You may need to re-pierce the tube seal or clear the nozzle when ready for next use.
Unopened, the product typically has a shelf life of 12-24 months when stored properly in a cool, dry environment.
The adhesive is waterproof, making it suitable for outdoor use and areas exposed to occasional moisture. For continuous submersion, specific marine-grade adhesives might be more appropriate.
Ensure the tube's seal is fully punctured and the nozzle is clear. Check if the caulking gun is properly engaged. For hardened adhesive in the nozzle, try carefully clearing it with a thin wire.
Verify that surfaces were properly cleaned, dried, and free of contaminants. Ensure sufficient adhesive was applied and materials were held together firmly during the initial grab period.
This can occur if the product is exposed to heat. Allow the adhesive to cool. Ensure the nozzle is cut to an appropriate size for the bead required.
Curing is dependent on temperature and humidity. Ensure the ambient temperature is within the recommended range (typically above 5°C/41°F). High humidity can sometimes speed up curing, while very low humidity can slow it down.
Setup: Ensure surfaces are clean, dry, and free from dust, grease, or loose material. Apply the adhesive in a continuous bead or in dabs using a caulking gun. Press the materials firmly together immediately after application. For heavy items, temporary support may be needed until full cure.
Compatibility: Suitable for wood, metal, concrete, brick, ceramics, plaster, insulation board, and some plastics. Always test on a small, inconspicuous area first if unsure.
Care: Store in a cool, dry place away from direct sunlight and extreme temperatures. Keep the tube sealed when not in use to prevent the adhesive from curing in the nozzle. Clean up any excess uncured adhesive immediately with a damp cloth or appropriate solvent. Cured adhesive can be removed mechanically.
