What is the best adhesive on concrete?

There are many adhesive products capable of sticking items to concrete but they have very different performance. Adiseal has been shown to be a great choice adhesive for heavy duty concrete bonding applications.

strongest adhesive for concrete

  • Adiseal is the record breaking strongest adhesive & sealant. It proved it’s the strongest adhesive in an independent adhesive strength test by Ultimate Handyman.
  • It stays permanently flexible, so the bond absorbs any vibration and allows bonded items to expand & contract without the bond becoming weak. A non-flexible adhesive can set hard and become brittle.
  • Adiseal is a weatherproof adhesive, waterproof sealant and waterproof adhesive, so it’s also suitable for use outside as well as for interior applications. It works in dry, wet & even underwater. Adiseal’s waterproof properties makes it a good adhesive for concrete pipe.
  • As long as the surface is clean of any dust, grease, paint or any other dirt, priming or sealing of the concrete or the other material should not be required.
  • It does not stain or bleed into concrete, stone or masonry.
  • Adiseal has very high gap fill properties. This is useful where there are gaps between the concrete and item that requires bonding to the concrete.
  • It has high initial grab meaning temporary supports may not be required while the construction adhesive cures. Adiseal Hi-Grab has even higher grab than the standard product, see below for details.
  • EC1 Plus certified (No VOC)
  • Suitable as an indoor and outdoor adhesive sealant for concrete and other materials.

Adiseal Adhesive & Sealant vs Adiseal Hi-Grab

Adiseal adhesive and sealant has high initial grab but for even more grab, use the Adiseal Hi-Grab adhesive. The final bond strength of both construction adhesives is similar. In the image below, we demonstrated the extra high initial grab of the Adiseal Hi-Grab adhesive. We applied the adhesive on the edge of the heavy concrete slab then grabbed the concrete slab with the other heavy concrete slab instantly.

Adiseal Hi-Grab adhesive also has higher gap-filling properties compared to Adiseal adhesive sealant. If you don’t require the extra high initial grab, the Adiseal adhesive sealant product is recommended for enhanced bonding.



How to attach wood to concrete

When it comes to attaching wood to concrete, Adiseal is a strong, reliable and durable adhesive product. It creates a strong and long-lasting bond between wood and concrete.

How to attach wood to concrete

  1. Reduce gap

    Minimise the gap between the wood and concrete surfaces. This can be done by cutting, filing, or sanding the surfaces to ensure an even contact area.

  2. Prepare the surfaces

    Ensure both surfaces are clean, dry, and free from dust. We recommend brushing the concrete with a fine brush like a painting brush to remove fine dust.

  3. Apply the adhesive

    Apply the adhesive then spread it evenly, covering the entire area where the wood will be attached.

  4. Position the wood

    Position the wood onto the adhesive the apply firm and even pressure to ensure good contact between the wood and the concrete surface.

  5. Clean excess

    Clean excess adhesive that may have squeezed out of the sides with a cloth and suitable cleaner. Once cured, this excess adhesive will need to be mechanically removed by cutting or breaking it.

  6. Secure the wood temporarily (optional)

    If required, use clamps, heavy weights or other temporary supports to hold the wood in place while the adhesive cures.

  7. Allow the adhesive to cure

    Give enough time for the adhesive to cure and avoid disturbing or putting stress on the bonded area during the curing process.


Tip: To store Adiseal once opened, leave about 1cm worth of product out of the nozzle and store the tube upright in a cool dry place. To re-use Adiseal, pull the cured part out or cut the nozzle until the uncured part is reached.


Cleaning concrete surface before applying the adhesive

For a high-quality bond, clean surfaces are essential prior to applying the adhesive. Dust, dirt or loose substrate can compromise the bond, particularly with concrete surfaces outdoors.

To clean concrete thoroughly, consider options like jet washing or sandblasting. Alternatively, use a mixture of water and suitable detergent with a stiff brush, but note that jet washing is more thorough. After using a detergent, ensure a thorough rinse to remove any residue before applying the adhesive. To remove fine dust, you can use a vacuum, blower, or a fine brush, like a paintbrush. This preparation step before applying the adhesive is vital for a strong bond.

In the image above, we showcased various materials bonded to concrete using Adiseal. Unlike competitor adhesives, no primer or sealer was required on our concrete demonstration block. We simply cleaned the surface thoroughly before applying the adhesive.


How to bond metal to concrete

Surface preparation is vital for a strong bond. Remove oil, dirt, dust, and grease from both surfaces using Adisolve for stubborn deposits.

Lightly scratch the metal surface where adhesive will be applied (may not always be necessary) using fine-grit sandpaper or a file. Clean thoroughly afterward to remove loose metal particles. Apply adhesive between metal and concrete, pressing firmly.

Use temporary supports if items start to slide. Adiseal Hi-Grab adhesive provides higher initial grab, reducing the need for supports in many cases. Allow sufficient curing time before removing temporary supports. Adiseal bonds to various metals including steel, iron, aluminum, copper, brass, lead, and more.

For added safety, use mechanical fixings along with adhesive when bonding heavy items to vertical or overhead surfaces. When drilling metal, Adiseal Ultimate metal drill bit outperforms others in speed and durability.

How to bond plastic to concrete

Adiseal bonds most plastics to concrete, except polypropylene, polyurethane, and polyethylene. Clean plastic thoroughly to remove dirt, oil, and grease. Increase bond strength by scratching the plastic surface. Apply adhesive and firmly press plastic onto concrete. Use temporary supports until adhesive cures. Allow sufficient curing time before removing supports.

How to bond rubber to concrete

Adiseal bonds natural rubber to concrete and various materials. Ensure clean surfaces for a quality bond. Apply adhesive to one surface, press rubber onto concrete firmly. Use temporary supports if needed until adhesive cures. Remove excess adhesive from edges before curing.

Please note Adiseal is suitable at bonding natural rubber but not synthetic rubber like neoprene.



How to bond stone, brick, tile or masonry to concrete

Adiseal is ideal for bonding stone, brick, tile, or masonry to concrete indoors or outdoors. Proper surface prep is key.

Brush off dust before applying adhesive. No priming needed with Adiseal if surfaces are clean. Adiseal doesn’t bleed into porous stones.

Ensure clean surfaces, especially from loose bits and dust. Apply adhesive to one surface, press firmly onto concrete. Use temporary supports if sliding occurs.

Adiseal Hi-Grab is recommended for heavier items, reducing the need for temporary supports.

Effective for bonding various stone types including marble, granite, travertine, slate, ceramic, and more.

For extra safety with heavy stone, brick, tile, or masonry items, use mechanical fixings along with Adiseal, especially for vertical or overhead applications.


Glue for concrete

If you’re looking for a glue specifically designed for gluing materials to concrete, our Adiglue glue is a suitable option. While Adiglue offers greater flexibility and strength compared to super glues, it is still not as flexible or strong as our Adiseal construction adhesive & construction sealant.

In the image above, we bonded a metal handle to a concrete slab with Adiglue. Before gluing, we sealed the concrete with Adiglue Activator to prevent glue absorption. However, Adiseal construction adhesive doesn’t require concrete sealing for the same purpose.



Glue for concrete vs concrete adhesive

Whether a glue for concrete is better to use or a concrete adhesive depends on the type of job and the surface area available for the bond between 2 materials.

If you have to bond to concrete items with a small surface area then Adiglue is the better product.

If the items that needing bonding to concrete have a large surface area, then Adiseal adhesive & sealant or Adiseal Hi-Grab adhesive are the best products to use.




What materials will Adiseal stick to concrete

Adiseal will successfully bond the following materials to concrete:




Cement adhesive

Concrete and cement, while related, are distinct construction materials. Here’s the difference:

Cement is a powdered binding material made from limestone, clay, shells, silica, and other elements. It binds ingredients to form a solid mass, crucial in concrete production. Types include Portland cement, widely used in construction.

Concrete is a composite of cement, aggregates (like sand or gravel), and water. Aggregates provide strength, while water activates cement’s hydration. Upon curing, it hardens into a versatile material used in construction for foundations, walls, floors, and more.

Mechanical fixings

It is also possible to attach items to concrete by using mechanical fixings like screws. Adiseal Ultimate is the fastest no-hammer masonry drill bit and multi material drill bit. It is suitable at drilling concrete, drilling brick, wood and other building materials.


Adiseal adhesive and sealant is available in the following colours:

Adiseal can also be manufactured in any RAL colour.

Please note Adiseal adhesive sealant colours provide a stronger bond on concrete and other materials compared to the clear version.
