Record Breaking Strongest Adhesive & Sealant

Adiseal adhesive & sealant destroyed the competition in an independent test. It was over 3 times stronger than the nearest competitor. Even the SCREWS STARTED RIPPING OUT in the test.

Instant Grab Adhesive

(Last Updated On: 9 June 2022)

Instant grab adhesive

An instant grab adhesive allows for items to be stuck together without needing to use temporary supports. Most adhesives take some time to fully cure. During this time, the adhesive will not have reached it’s potential maximum holding power. This may cause the materials to slide or pull apart during this time, as the adhesive between them is not strong enough to counter the force. An instant grab adhesive has extra high initial grab. Using it can save time and money as it eliminates the need for installing and removing temporary supports.

Adiseal Hi-Grab extra high instant grab adhesive has a heavy duty power grab and bond strength. It stays flexible and is a waterproof adhesive as well. Adiseal Hi-Grab works in the dry & wet and is suitable for both indoor and outdoor use. In this article we will also look at how to use an instant grab adhesive.

Adiseal Hi-Grab is based on the same pro grade polymer technology as the record breaking strongest adhesive, Adiseal construction adhesive and sealant but with even higher instant grab. Adiseal Hi-Grab has a thicker consistency compared to Adiseal adhesive and sealant. This gives Adiseal Hi-Grab extra initial holding power compared to Adiseal adhesive and sealant.

Great instant grab adhesive on vertical surfaces

When items are being stuck to a vertical surface, before the adhesive cures, there is a higher chance of it sliding down and moving away compared to if it was being stuck to a horizontal surface. This will require the use of temporary supports to hold the item in place until the adhesive cures. This can increase the amount of time required to complete a project a a job may need to be revisited to remove the temporary supports. For trades people this time will also cost money.

Since Adiseal Hi-Grab has such high instant grab power, it is possible to bond many items without the need for temporary supports. It is especially great on vertical walls where other construction adhesives with lower instant grab would result in the item sliding down.

Application:

To get a good adhesive bond, surface preparation is very important. 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 and longer lasting bond. The Adisolve spray is the ideal product to clean and prepare surfaces.

On some surfaces like concrete (especially outside), simply brushing the surface might not remove the dirt stuck to the surface. It is recommended to use a jet wash, sand blaster or a detergent with a thick brush to help clean the concrete surface thoroughly.

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 thin vertical strips. This allows the water to run down between the construction adhesive instead of building up on top. A build up of water between the items can place additional stress on the adhesive as this water may freeze and expand in cold temperatures.


Instant grab adhesive initial holding power performance demonstration

As can be seen in the video below, Adiseal Hi-Grab has phenomenal instant power grab and bond strength. To demonstrate the power grab and bond strength, we used 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 surface area, we applied it to the edge of the concrete with a smaller surface area. As the video shows, the 2 concrete slabs gripped each other straight away due to the phenomenal instant power strength of Adiseal Hi-Grab.

Bonding items with Adiseal Hi-Grab

Adiseal Hi-Grab will successfully bond the following items:



How to use instant grab adhesive

How to use instant grab adhesive.

  1. Choose correct product.

    Choose which is the correct product to 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 strongest 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 and any other dirt first. Using a fine brush like a paint brush will help remove fine dust.

  3. Apply the correct amount of adhesive.

    Apply the correct amount of adhesive. Instant grab adhesives are usually thicker than other adhesives. This can provide extra strong initial grab but it can also make it difficult to push the two surfaces close together. Since Adiseal Hi-Grab is a thick product, it will require a good quality applicator (sealant gun) to get the product out of the cartridge. Using a cheaper applicator will make it difficult to get the product out of the tube.

  4. Push items together.

    Firmly push the items together. Moving the items slightly side to side while pushing can spread the adhesive, covering a larger surface area and increase the final bond strength.

  5. Hold items in place.

    Hold items in place until the adhesive dries. With Adiseal Hi-Grab, there is usually no need to use temporary supports but this can vary depending on material, weight and surface.

Frequently Asked Questions About Instant Grab Adhesive

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

Grab adhesives tend to have a lower initial grab and grip compared to instant grab adhesives. If an adhesive does not have sufficient initial grab power then temporary supports may need to be used to hold the items in place, until the adhesive reaches its potential maximum holding power by curing. This is a greater problem on vertical surfaces where items tend to slide down.

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 or pulling away. This saves the user time as they don’t need to use temporary supports to hold the item in place until the adhesive cures and reaches maximum holding power.

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 main difference is the initial grab. If there is no need for extra high instant 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 it requires a lot higher pressure to push the 2 surfaces together. Using a thinner adhesive allows for the items to be pushed closer together, resulting in a better bond.
