Adiseal Waterproof Adhesive Glue

Adiseal waterproof adhesive sticks items in dry, damp or wet conditions. It provides a water resistant, high strength, durable and flexible bond, even in the wet. Adiseal waterproof adhesive has been shown to be the strongest adhesive in an independent adhesive strength test where it was shown to be over 3 times stronger than the next best product.

Adiseal Waterproof Adhesive

Most adhesives require dry conditions for the adhesive to work. Adiseal is a high performance waterproof adhesive that bonds in dry, damp, wet and even underwater. It grabs items whether the surface is dry or wet.

Strongest waterproof adhesive in test

One of Adiseal’s standout features is its ability to cure underwater. This remarkable characteristic opens doors to a multitude of possibilities, making it perfect for marine and water-related projects. No matter the challenge, Adiseal can securely bond materials together.

Strongest waterproof adhesive

In a series of independent tests conducted by Ultimate Handyman to determine the strongest adhesive, Adiseal emerged as the undisputed frontrunner, outperforming its competitors by a substantial margin.

The evaluation involved applying each adhesive between hardwood and metal surfaces and subjecting them to pressure using a hydraulic ram to measure the breaking point of each bond. Adiseal demonstrated exceptional strength, surpassing its closest competitor by more than three times.

The immense power of Adiseal was evident as the test rig’s screws began to tear out, and even the hydraulic ram seal gave way, leading to the test’s early termination. Adiseal proved its formidable strength, establishing itself as the unequivocal champion and the strongest adhesive in the competition.

Test results

In the assessment of bond strength between hardwood and metal, Adiseal exhibited an astounding resistance to pressure, withstanding over 3123+ psi. In contrast, all other grab adhesives faltered at 1115 psi or lower. The chart below unequivocally highlights Adiseal as an incredibly potent grab adhesive, boasting unparalleled strength in its performance.

How to Use a Waterproof Adhesive

How to use a waterproof adhesive

  1. Surface Preparation

    Thoroughly clean and dry the surfaces to be bonded. Remove any dust, dirt, grease, or debris that could hinder adhesion. Smooth or roughen the surfaces if needed for better bonding.

  2. Apply the Adhesive

    Apply the adhesive to the material that requires bonding. Covering more surface area with the waterproof adhesive will provide a better bond.

  3. Join the Surfaces

    Carefully align the surfaces to be bonded and press them firmly together. Ensure there is full contact between the adhesive and the materials to achieve a strong bond. Sliding the items slightly before the adhesive cures can help spread the adhesive.

  4. Curing Time

    Allow the adhesive to cure according to the manufacturer’s instructions. This may vary depending on the type of adhesive used. Avoid stressing or moving the bonded materials during the curing process.

  5. Temporary support (not always necessary)

    If the items do not stay in place until the waterproof adhesive cures then use temporary supports to hold them in place.

  6. Clean Excess Adhesive

    Wipe off any excess adhesive that may have squeezed out during bonding. Use a suitable solvent or adhesive remover if necessary.

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.
