Surface preparation is crucial for achieving a strong and durable adhesive bond. Taking the time to thoroughly clean surfaces by removing dust, grease, paint, and other contaminants will ensure a superior and long-lasting bond. For optimal surface preparation, the Adisolve spray is the ideal product to clean and prepare surfaces effectively.

When dealing with concrete surfaces, especially outdoors, simply brushing may not be sufficient to remove stubborn dirt. It is recommended to use more intensive methods such as jet washing, sand blasting, or using a detergent with a sturdy brush to achieve a thorough clean.

When using Adiseal Hi-Grab construction adhesive in vertical applications where water runoff is a possibility, it is advisable to apply the adhesive in thin vertical strips. This allows water to flow down between the adhesive strips, preventing water buildup on top. Accumulated water between items can create additional stress on the adhesive, particularly during freezing temperatures when the water expands.

By prioritizing proper surface preparation and implementing these expert tips, you can achieve a superior adhesive bond that stands the test of time.

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.

How to use instant grab adhesive.

  1. Choose the correct product.

    Selecting the right instant grab adhesive for your specific application is crucial. Certain materials, like polypropylene and polyethylene, can be challenging to bond, and may require surface treatment to enhance adhesion. Make an informed choice to ensure optimal bonding results.

  2. Clean the surface.

    A strong adhesive bond relies on a clean surface. Prior to applying the adhesive, thoroughly clean the surface to remove dust, grease, and dirt. Using a fine brush, such as a paint brush, can help remove fine dust particles for better adhesion.

  3. Apply the correct amount of adhesive.

    Apply the correct amount of adhesive: Instant grab adhesives are typically thicker than other adhesives, providing enhanced initial grip. However, this thickness can make it difficult to bring surfaces close together. When using a product like Adiseal Hi-Grab, a high-quality applicator (sealant gun / caulking gun) is recommended for smooth dispensing.

  4. Push items together.

    Firmly push the items together, while gently moving them side to side. This motion helps evenly spread the adhesive, covering a larger surface area and promoting a stronger bond.

  5. Hold items in place.

    While Adiseal Hi-Grab often eliminates the need for temporary supports in most occasions, it’s important to hold the items in place until the adhesive fully dries. Factors such as material, weight, and surface condition may affect the need for additional support.


Using instant grab adhesives comes with certain safety implications that should be considered. Here are a few key points:

  1. Skin and eye protection: Instant grab adhesives are often strong and fast-acting, which means they can bond to skin or cause irritation if they come into contact with it. It’s essential to use the correct PPE, to wear protective gloves and safety goggles when handling and applying these adhesives to avoid skin contact and protect the eyes.
  2. Adequate ventilation: Some instant grab adhesives, especially if they contain solvents, may emit fumes or have strong odors. To ensure a safe working environment, it’s important to use these adhesives in well-ventilated areas. Open windows or use fans to improve air circulation and minimize exposure to potentially harmful fumes.
  3. Proper storage: Store instant grab adhesives in a cool, dry place, away from direct sunlight and sources of heat. Follow the manufacturer’s guidelines for storage temperature and shelf life to maintain the adhesive’s effectiveness and prevent any potential safety hazards.

  6. Heavy items: Be careful of relying on adhesives only for heavy items items. Adhesives have a shelf life and if they do fail in the future, a heavy item may fall and cause damage to property or even injure someone if they’re directly below. It is recommended to also add additional mechanical fixings to be on the safe side.

Common problems

When using instant grab adhesives, several common problems may arise. Here are a few examples:

  1. Improper bonding surface preparation: Insufficiently cleaning or preparing the bonding surfaces can result in weak adhesion. Dust, grease, or other contaminants on the surface can hinder the adhesive’s effectiveness. It is crucial to thoroughly clean and dry the surfaces before applying the adhesive for optimal bonding.
  2. Inadequate adhesive application: Applying too little or too much adhesive can lead to bonding issues. Insufficient adhesive may result in weak bonds, while excessive adhesive can cause messy application, excessive squeeze-out, or difficulty in aligning and joining the materials.
  3. Lack of proper curing time: Instant grab adhesives typically have an initial grab, but they still require sufficient curing time to reach their full strength. Rushing the process and not allowing adequate curing time can result in weaker bonds that may fail over time.
  4. Unsuitable adhesive for the materials: Different materials require specific types of adhesives. Using an instant grab adhesive that is not suitable for the specific materials being bonded can lead to poor adhesion or even damage to the materials.
  5. Storage and shelf life issues: Improper storage or using expired adhesive can affect its performance. It is important to store instant grab adhesives according to the manufacturer’s instructions, including temperature requirements and shelf life limitations. Using expired or improperly stored adhesive may result in weaker bonding properties.
  6. Temperature and environmental considerations: The performance of instant grab adhesives can be influenced by temperature and environmental conditions. Extreme heat or cold can affect their bonding properties, so it is important to follow the manufacturer’s guidelines regarding temperature range for application and storage.
  7. Load-bearing capacity: While instant grab adhesives provide initial strength, they may not have the same load-bearing capacity as other structural adhesives or mechanical fasteners. If the application requires heavy loads or long-term structural support, it is important to consult the manufacturer’s specifications or consider alternative bonding methods.

By being aware of these common problems, following proper application techniques, and selecting the right adhesive for the materials, you can mitigate potential issues and achieve strong, reliable bonds with instant grab adhesives.
