Instant Hold Adhesive

Instant Hold Adhesive: Fast Heavy Duty Grab

Adiseal Hi-Grab instant hold adhesive has very fast initial grab and provides a strong bond. When attempting to stick items together with an adhesive, some adhesives can take some time to reach full bond strength. During the period between adhesive application and the adhesive achieving full strength, temporary supports might need to be used to hold items in place. This can increase the amount of time to carry out the bonding job and cost more money in labour costs. Using an adhesive with instant hold may eliminate the need to use temporary supports, saving time and money.

Adiseal Hi-Grab, with its rapid high instant hold adhesive strength, minimizes the requirement for temporary supports. In contrast to other construction adhesives, it guarantees secure positioning on vertical walls, preventing objects from sliding, enhancing efficiency, and reducing overall costs.

Instant grab adhesive hold performance demonstration

Observe the extraordinary instant power grab and bond strength of Adiseal Hi-Grab instant hold adhesive in the following video. We carried out a test using two 32 Kg concrete blocks, pushing the limits by applying the adhesive on the edge of the concrete with a smaller surface area instead of the side with the largest surface area. As depicted in the video, the two concrete slabs promptly secured each other, showcasing the remarkable instant power of Adiseal Hi-Grab.

How to use instant hold adhesive

How to use instant hold adhesive.

  1. Surface Preparation

    Ensure that the surfaces to be bonded are clean, dry, and free from dust, grease, or debris.
    If necessary, roughen smooth surfaces for better adhesion.

  2. Apply the adhesive

    Apply the adhesive on one of the surfaces. Ensure the bead is uniform and covers as much bonding area as possible to get a better bond.

  3. Join the surfaces

    Press the two surfaces together immediately after applying the adhesive. Adiseal Hi-Grab is designed for instant grab, so work quickly. Align the items accurately as repositioning may be challenging once the adhesive has set.

  4. Secure or support if needed

    In some cases, especially on vertical surfaces, you might need to provide temporary support until the adhesive cures.

  5. Curing time

    Instant grab adhesives offer an immediate hold, yet it’s essential to adhere to the manufacturer’s guidelines regarding the curing time for optimal strength attainment.

  6. Clean up

    Remove any excess adhesive that may have squeezed out when joining the materials together. A suitable solvent or cleaner can be used to help remove excess adhesive.


Tip: To store Adiseal once opened, leave about 1cm worth of product out of the nozzle and store the tube upright in a cool dry place. Adiseal requires moisture for it to cure. The exposed part out of the nozzle will cure creating a cap. To re-use Adiseal, pull the cured part out or cut the nozzle until the uncured part is reached.
