Why Adiseal is a great adhesive for panels

Adiseal is the perfect adhesive for paneling due to its record-breaking strength, flexibility, waterproof properties, and other key features:

Strong adhesive for panels.
  1. Unmatched strength: Adiseal has undergone independent testing and proven to be the strongest adhesive and sealant available.
  2. Flexible and durable: It maintains flexibility to accommodate vibrations and movements without weakening or becoming brittle.
  3. Waterproof performance: Adiseal is fully waterproof, making it suitable for both indoor and outdoor applications, including underwater use.
  4. No priming required: Save time and money as Adiseal does not require priming, as long as the surface is clean.
  5. Non-staining formula: Adiseal won’t stain or bleed into marble, stone, or other porous materials, preserving their appearance.
  6. Excellent gap-filling properties: Even on uneven surfaces, Adiseal provides high gap fill capabilities for a strong bond.
  7. Strong initial grab: Adiseal offers a high initial grab, reducing the need for temporary supports during the curing process. Adiseal Hi-Grab is available for more demanding applications where even higher initial grab is required.


The record breaking strongest Adiseal adhesive and sealant will bond and seal on many different materials.

In a demonstration, we bonded a concrete block and PVC together using Adiseal adhesive and sealant. Despite the concrete being porous, we achieved a strong bond without the need for surface sealing. Adiseal’s exceptional performance properties allow it to adhere to porous surfaces without bleeding or staining concerns.

Strongest adhesive in independent test

In an independent adhesive strength test, Adiseal surpassed its closest competitor by over three times in adhesive strength. The test had to be stopped at 3123 psi as the screws securing the test rig started to tear out. Adiseal would have achieved even greater strength if the screws had not given way. Rest assured, with Adiseal, you can trust in its exceptional strength and reliability for all your bonding needs.

Adiseal Adhesive Sealant vs Adiseal Hi-Grab

For an adhesive with higher strong initial grab, consider Adiseal Hi-Grab. It provides an even stronger initial grab than the standard Adiseal adhesive, making it perfect for heavy-duty applications or scenarios where temporary supports cannot be used during the curing process. Both Adiseal adhesive sealant and Adiseal Hi-Grab offer comparable final bond strength.

How to bond panels to wall

Adiseal bonds panels to walls, ceilings and other surfaces effectively, creating a strong and durable bond suitable for both indoor and outdoor applications. Before applying the adhesive, it’s crucial to ensure clean surfaces free from dust, grease, paint, or any other debris. Using a fine brush, such as a painting brush, can help remove fine dust and prepare the surfaces for bonding.

Before applying the adhesive, ensure the concrete surface is dust-free. We recommend using a fine brush like a painting brush to remove fine dust from masonry.

Once the surfaces are clean, apply the adhesive to either the panel or other surface and firmly press them together. When bonding in a potentially wet area, apply Adiseal in thin vertical strips to allow water to run down between the strips and prevent water buildup that can weaken the bond. In cold temperatures, this water may freeze and expand, compromising the bond.

Temporary supports may not be necessary, but if the panel starts to slide, consider using temporary supports until the adhesive cures, which can take up to 48 hours.

For wood panels, as wood tends to absorb moisture and expand, it’s crucial to use a flexible adhesive when bonding wood panels. This flexibility allows for expansion and contraction without making the bond brittle.

For added safety when bonding heavy wood panel items in vertical or overhead applications, it is recommended to use mechanical fixings along with an adhesive.

How to stick panels with a panel adhesive

How to stick panels with a panel adhesive

  1. Prepare the surfaces

    Ensure that both the panel surface and the surface you want to bond it to are clean, dry, and free from dust, dirt, grease, or any other contaminants. Clean the surfaces using a mild detergent and water if needed.

  2. Apply the adhesive

    Apply a thin, even layer of adhesive to either the panel surface or the surface you want to bond it to. You can use a brush or a suitable applicator to spread the adhesive evenly.

  3. Press and hold

    Carefully align the panel piece with the target surface and firmly press it into place. Apply even pressure across the entire surface to ensure a strong bond. Hold the panel in place for a few moments to allow the adhesive to start bonding.

  4. Cure time

    Follow the instructions provided by the adhesive manufacturer regarding the recommended curing time. Adiseal typically takes around 24-48 hours to fully cure, but the exact time may vary depending on factors such as temperature and humidity.

  5. Avoid movement

    Avoid disturbing or putting stress on the bonded panel during the curing process. This will help ensure a strong and durable bond.

Tip: When bonding items in a potentially wet environment, apply the adhesive in thin vertical strips. This enables water to drain between the strips, preventing it from pooling on the adhesive. Accumulated water can freeze in cold temperatures, exerting extra forces on the adhesive.


Adiseal is available in the following colours:

Please note the Adiseal adhesive for panels colours are stronger and have a higher initial grab than the clear version.
