Frequently Asked Questions About Adiseal Hi-Grab Adhesive Sealant
Can Adiseal Hi-Grab hold heavy items on walls without support?
Yes. Adiseal Hi-Grab is specifically engineered with an ultimate initial power grab, allowing it to bond heavy items to vertical surfaces instantly. It eliminates the need for temporary supports or “propping” on most applications, saving significant time during construction and DIY installations.
What is the difference between Adiseal Hi-Grab and Adiseal Adhesive & Sealant?
While both provide a record-breaking bond, Adiseal Hi-Grab has a much thicker consistency designed for immediate vertical hold (high initial grab). The standard Adiseal Adhesive & Sealant is thinner, making it easier to use as a sealant and for applications where a high initial grab is not the primary requirement.
How strong is the final bond of Adiseal Hi-Grab?
Once fully cured, Adiseal Hi-Grab provides a high-performance, flexible bond that is even stronger than the record-breaking Adiseal Adhesive & Sealant. It is a professional-grade MS polymer that is waterproof, UV resistant, and proven to outperform leading competitors in independent strength tests.
Professional Tip: Because Adiseal Hi-Grab is engineered with a much thicker, high-viscosity formula to achieve its high instant hold, it requires a high-quality, caulking gun (sealant gun) for application. Standard or “budget” DIY guns may struggle to dispense the product efficiently and could even break under the pressure. Using a professional gun with a higher mechanical advantage ensures a smooth, consistent bead and reduces hand fatigue during large-scale vertical installations.
How do you apply Adiseal Hi-Grab adhesive for the best results?
How to Apply Adiseal Hi-Grab Adhesive for a Professional Bond
Prepare and Clean the Surfaces
For the strongest possible bond, ensure surfaces are free from dust, grease, and loose material. While Adiseal works on wet surfaces, removing heavy debris first improves initial contact. If applying to metal, a quick wipe with a solvent-based cleaner is recommended.
Prepare the Adiseal Cartridge
Cut the top off the threaded plastic stud on the 290ml cartridge. Screw on the included nozzle. Place the cartridge in the caulking gun / sealant applicator.
Apply the Adhesive
For Bonding: Apply Adiseal in vertical “strips” (beads) rather than blobs. This allows air to circulate for faster moisture-curing. Press the two materials together firmly.
Allow for Curing Time
Adiseal has a high initial grab. Under normal conditions, it skins over in 10–20 minutes and is recommended 48 hours to fully cure.
Other colours Adiseal adhesive sealant is available include: White, Black, Grey and Brown.
