Gap Filling Adhesive

GAP FILLING ADHESIVE: High Grip, Fill & Strength

Adiseal gap-filling adhesive is a high-performance adhesive that has superior gap-fill and extra strong adhesion. Compared to solvent-based adhesives like Gripfill, Adiseal’s solvent-free formula does not shrink, resulting in higher gap-fill and stronger bond strength.

Solvent-based adhesives shrink as the solvents evaporates away during the curing process. This makes the shrinking adhesive pull away from the material surface, resulting in lower gap-fill and weaker bond strength. As Adiseal is solvent-free, it does not shrink and it has also been shown to be the strongest adhesive in an independent adhesive strength test.

Best gap filling adhesive. Strongest in test.


Why use a gap-filling adhesive?

When attempting to stick items together, there may be uneven places where the surfaces of the materials do not closely match, leaving large gaps between the surfaces. An adhesive that is capable of filling in these gaps provides a better quality adhesive bond.

What is the best gap-filling adhesive?

Adiseal has been shown to be the strongest adhesive in an independent adhesive strength test by Ultimate Handyman. No other adhesive even came close to matching the remarkable capabilities of Adiseal. To witness the test results firsthand, you can watch the video provided below.

 

The best gap fill adhesive was Adiseal

During the independent tests conducted by Ultimate Handyman, Adiseal emerged as the clear winner and the best gap filling grab adhesive in the market. Adiseal surpassed all other tested adhesives by a significant margin and proved to be over three times stronger than the next best product. The test had to be prematurely halted due to the extraordinary strength of Adiseal. The screws securing the metal sheet began to tear out, and the hydraulic ram seal broke resulting in fluid leakage, making it too strong for the testing rig to handle.

How to use a gap filling adhesive

How to use a gap filling adhesive

  1. Prepare the surfaces

    Ensure the surfaces you plan to bond are clean, dry, and free from dust, grease, or other contaminants.

  2. Apply the adhesive

    Apply the adhesive directly into the gap. Start from one end and work your way along the entire length of the gap, filling it as evenly as possible.

  3. Press the surfaces together

    Immediately after applying the adhesive, bring the surfaces you want to bond together. Apply firm pressure to ensure good contact between the adhesive and the surfaces.

  4. Secure the bond

    If needed, use clamps, tapes, or other means to hold the surfaces in place while the adhesive cures.

  5. Clean up excess adhesive

    Remove any excess adhesive that may have squeezed out from the gap or along the edges.

  6. Allow for proper curing

    Depending on the adhesive, it may take some time for the bond to reach its full strength.


Solvent free gap-filling adhesive

Solvent-free Adiseal adhesive has numerous advantages over solvent-based adhesives like Gripfill. Solvents can negatively impact gap-filling and bond strength. Adhesives based on solvents cure by the evaporation of solvents, leaving behind less active product between the materials that require bonding. As the adhesive undergoes curing and shrinks, it can potentially detach from the adhered material, leading to a diminished bond strength and reduced ability to fill gaps. Watch the video showing how solvent-based Gripfill adhesive shrinks as the solvent evaporates away.

Materials it can can bond

Adiseal is a versatile and high-performance product that can successfully bond a wide variety of materials, including:

 

 

 

Applications & Benefits

Many other benefits of Adiseal include:


 

Colours

Adiseal adhesive and sealant is available in the following colours:

Adiseal can also be manufactured in any RAL colour.


Solvent-free gap filling grab adhesive

Adiseal is an extra strong solvent-free gap-filling grab adhesive known for its exceptional bonding strength. For even stronger grip, consider Adiseal Hi-Grab adhesive, which has a thicker consistency. Note that a high-quality sealant gun (caulking gun) is needed to dispense it due to its thickness. Adiseal Hi-Grab adhesive can fill even larger gaps than the Adiseal adhesive sealant product.

For most bonding applications, we recommend using Adiseal adhesive sealant over heavy-duty Adiseal Hi-Grab. Although their final bond strengths are similar, Adiseal Hi-Grab’s thick consistency necessitates higher force to push the materials together. Minimizing the gap can enhance adhesive bond quality.


Where to buy gap filling adhesive

Frequently asked questions about gap filling adhesive

What is the best-gap filling adhesive?

Adiseal was found to be the strongest adhesive on the market, outperforming all other products tested. Adiseal is solvent-free, ensuring that it doesn’t shrink or crack over time. Its flexible and waterproof properties make it ideal for a wide range of applications.

What is gap-filling adhesive?

It is a type of adhesive specifically designed to fill and bond gaps between surfaces. It provides a better bond than other adhesives, when there are gaps between the 2 materials that require bonding.

What are the benefits of using a gap-filling adhesive?

They provide effective bonding and bridging of uneven or irregular surfaces.
They help create a seamless and aesthetically pleasing finish and improve the strength and stability of the bond, even in challenging conditions.

What is the best adhesive for filling gaps?

Adiseal has been shown to be the strongest adhesive in an independent adhesive strength test. It finished over 3 times stronger than the next best product. Its solvent-free formula means it does not shrink. It also provides a flexible, waterproof and durable adhesive bond.

What construction adhesive fills gaps?

Adiseal is a construction adhesive that also fills gaps. Its solvent-free formula means it does not shrink unlike solvent based products.

How do you fill a large gap with sealant?

To fill a large gap with a sealant, cut the nozzle extra large to apply more sealant into the gap. You can overfill it slightly as the sealant will move into any gaps as you try to smooth it.
