Best Grab Adhesive: Strongest Bond

Adiseal grab adhesive is a high-performance product that provides a strong and heavy-duty bond. It has been shown to be the strongest grab adhesive in an independent grab adhesive strength test. Adiseal provides a strong, flexible, waterproof, gap-filling and durable bond that also has the added advantage of grabbing materials quickly which can potentially save time and money on labour costs.

What is the best grab adhesive?

Ultimate Handyman conducted an independent adhesive strength test to determine the best grab adhesive. The results crowned Adiseal as the top performer. Adiseal’s strong adhesive bond exceeded the test rig’s capacity, causing the screws holding it to begin to rip out before Adiseal’s bond broke. The test on Adiseal had to be abandoned.

Test results

In the adhesive bond strength test between wood and metal, Adiseal demonstrated remarkable resilience, enduring pressures exceeding 3123+ psi. In contrast, all other competitors failed at 1115 psi or lower, making Adiseal more than three times stronger than the closest rival. The chart below vividly underscores Adiseal’s exceptional strength.

Higher instant grab hold

Adiseal adhesive and sealant has high initial grab but for even more initial grab, try the Adiseal Hi-Grab adhesive.

Adiseal Hi-Grab is the ultimate instant grab adhesive designed to deliver heavy-duty power grab and bond strength. This waterproof adhesive boasts flexibility, making it ideal for both dry and wet applications, indoors and outdoors. Using the same pro-grade polymer technology as our Adiseal construction adhesive and sealant, Adiseal Hi-Grab takes instant hold adhesive to even greater heights. Its thicker consistency ensures superior initial holding power, surpassing even the performance of Adiseal adhesive and sealant.

For most adhesive bonding applications, we suggest using Adiseal adhesive & sealant over Adiseal Hi-Grab. This preference arises because Adiseal Hi-Grab is notably thick, demanding greater force to bring two items together and necessitating a high-quality caulking gun (sealant gun) for smooth dispensing due to its thickness.

Great grab adhesive on vertical surfaces

When bonding items vertically, the risk of downward sliding increases due to gravity pulling the item down while the adhesive resists. Adiseal Hi-Grab excels in bonding heavy items on vertical surfaces, eliminating the need for temporary supports. Its outstanding grip prevents downward movement, resulting in time and labour cost savings.

Which materials will it bond?

Adiseal adhesive sealant and Adiseal Hi-Grab will both successfully bond the following items:

 

How to use a grab adhesive

How to use a grab adhesive.

  1. Surface Preparation

    For a robust bond, prepare surfaces by ensuring they are clean, dry, and free from dust, grease, paint, or contaminants. Use a fine brush, such as a paintbrush, to remove fine dust on surfaces like concrete.

  2. Cut the Nozzle

    If your product comes in a tube, cut the nozzle to create an appropriate-sized opening. The size of the nozzle opening will determine the thickness of the adhesive bead.

  3. Apply the Adhesive

    Apply an even adhesive bead along one surface. Wider adhesive coverage ensures a stronger bond compared to limited coverage.

  4. Join the Surfaces

    Once the adhesive is applied, join the two surfaces together. Apply firm pressure to ensure good contact between the surfaces.

  5. Adjustment

    Certain products provide a brief adjustment time to align bonded items. Use this time to make necessary adjustments, and gently slide surfaces side to side for adhesive distribution, improving bonding.

  6. Curing Time

    Allow the adhesive to cure as per the manufacturer’s instructions. The curing time may vary depending on the specific adhesive and environmental conditions.

  7. Cleanup

    If there is any excess adhesive that squeezed out during bonding, clean it up using a suitable solvent or as directed by the adhesive manufacturer.

  8. Storage

    After use, seal the adhesive tube or cartridge tightly for future use, ensuring it remains in good condition.

 

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.
