To get a good adhesive bond, surface preparation is key. Spending extra time to make sure the surfaces you are trying to bond are free of dust, grease, paint & any other dirt will allow you to have a much stronger bond. The Adisolve spray is the ideal product to clean & prepare surfaces.

If using Adiseal Hi-Grab construction adhesive where there is a chance water will run behind the item, it is advisable to apply the adhesive in vertical strips. This allows the water to run down between the construction adhesive instead of building up on top.

As you can see in the video, it has phenomenal instant power grab & bond once it’s cured. We tested the power grab & bond strength using 2 concrete blocks weighing 32 Kg in total. To test it to the extreme, instead of applying the construction adhesive on the side with the largest cross sectional area, we applied it to the small side. The 2 concrete slabs gripped each other straight away due to the phenomenal instant power strength.

How to use instant grab adhesive

How to use instant grab adhesive.

  1. Choose correct product.

    Choose which is the correct product use for the application. Some materials like polypropylene and polyethylene can be difficult to bond. Some products require treatment to increase the surface energy of the material to be able to bond.

  2. Clean surface.

    An adhesive bond is only as strong as the surface it is stuck on. Even with the best instant grab adhesive, trying to stick something to a dusty surface will provide a weak bond. Cleaning the surface is required before applying the product. Remove any dust, grease & any other dirt. Brushing with a fine brush like a paint brush will help remove fine dust.

  3. Apply correct amount of adhesive.

    Apply the correct amount of adhesive. Instant grab adhesives are usually very thick. This can provide extra strong initial grab but it can also make it difficult to push the two surfaces close together.

  4. Push items together.

    Firmly push the items together.

  5. Hold in place.

    Hold items in place until the adhesive dries.

Frequently Asked Questions (FAQ’s)

What is the difference between grab adhesive and instant grab adhesive?

Grab adhesives tend to have a lower initial grab and grip than instant grab adhesives. The initial power grab of instant grab adhesives make them more suitable for use on vertical surfaces as heavy items tend to slide down if the adhesive does not have enough grab or grip.

Is Adiseal Hi-Grab instant grab adhesive suitable for outdoors?

Yes it is suitable for use outdoors as it is waterproof and flexible. It is also UV resistant making it ideal for indoor and outdoor use.

Where would you use an instant grab adhesive instead of a standard grab adhesive?

As the initial grab on an instant grab adhesive is higher than standard adhesives, it allows the user to simply stick the item they are bonding to a surface and not worry about the item sliding down. This saves the user time as they don’t need to put temporary supports to hold the item in place until the adhesive has cured.

What is stronger Adiseal adhesive and sealant or Adiseal Hi-Grab?

The final bond strength of both Adiseal and Adiseal Hi-Grab are similar. The only difference is the initial grab. If there is no need for extra high initial grab or if temporary supports can be used while the adhesive dries then it is recommended to use the Adiseal adhesive and sealant. The reason for this is because Adiseal Hi-Grab is a very thick product therefore requiring a lot higher pressure to push the 2 surfaces together. Having the 2 surfaces are close together will result in a much stronger bond.
