What is the best brick adhesive?

Some of the reasons why Adiseal adhesive & sealant is the best product to glue to brick include:

  • Adiseal is the record breaking strongest adhesive & sealant. It proved it’s the best in an independent adhesive strength test by Ultimate Handyman.
  • Adiseal stays permanently flexible so it will absorb any vibration and allow any items to expand & contract without the construction adhesive becoming weak.
  • Adiseal is waterproof so it is also suitable for use outside. It works in dry, wet & even underwater.
  • As long as the surface is clean of any dust, grease, paint or any other dirt, priming the material should not be required.
  • It does not stain or bleed into brick, stone, marble or masonry.
  • Adiseal has very high gap fill properties.
  • 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.
  • With Adiseal, the concrete, stone, masonry or brick does not require sealing prior to applying the adhesive.
  • Suitable for use as an indoor and outdoor adhesive.


Strongest adhesive in independent test

In an independent adhesive strength test by Ultimate Handyman, Adiseal outperformed the competition by over 3 times. The screws holding the test rig down even began to rip out, necessitating the termination of the Adiseal test.

Instant grab adhesive

Adiseal brick adhesive offers high initial grab, but for even greater initial gripping power, consider Adiseal Hi-Grab adhesive. Both construction adhesives provide a similar final bond strength, but Adiseal Hi-Grab offers an exceptionally strong initial hold. The example below illustrates the remarkable initial grip of Adiseal brick adhesive sealant on both dry and wet brick surfaces. We poured water over the brick before applying the adhesive on top of the wet surface. We then lifted up the wet brick straight away with another brick to demonstrate the high adhesive grab of Adiseal.

How to stick wood to brick

How to stick wood to brick.

  1. Prepare the Surfaces

    Clean both wood and brick surfaces thoroughly, eliminating dust, dirt, and loose particles. Use a clean cloth or brush to remove debris. For finer dust, consider using a painting brush.

  2. Apply the Adhesive

    Apply enough adhesive to create a solid bond but avoid using excessive amounts that may squeeze out from the edges when pressure is applied.

  3. Position the Wood on the Brick

    Carefully position the wood onto the brick, aligning it with the desired location. Apply firm and even pressure to ensure good contact between the wood and the brick surface.

  4. Secure the Wood

    If necessary use clamps or temporary supports to hold the wood in place while the adhesive cures. This will prevent the wood from sliding or shifting before the adhesive sets.

  5. Remove Excess Adhesive

    If any adhesive squeezes out from the edges of the wood, use a putty knife or a damp cloth to remove it before it fully cures.

  6. Allow Sufficient Curing Time

    Give the adhesive enough time to fully cure as per the manufacturer’s instructions. Avoid putting excessive stress or load on the wood during this curing period.


When attaching wood to brick, it’s important to consider that wood can absorb moisture from the air and expand or contract as a result. For this reason a flexible adhesive like Adiseal is recommended to glue brick to wood.

For safety reasons when attaching extra heavy wood in vertical & overhead applications, mechanical fixings should also be used between the wood and brick in conjunction with Adiseal.

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. Adiseal requires moisture for it to cure. The exposed part out of the nozzle will cure creating a cap. To re-use Adiseal, pull the cured part out or cut the nozzle until the uncured part is reached.



How to attach metal to brick

For strong and lasting metal-to-brick bonds, Adiseal is an excellent choice, offering a waterproof, flexible bond. Clean surfaces are crucial for optimal bonding.

Some metals might have an oil coating to prevent rust, which should be removed before applying the adhesive. Adisolve effectively eliminates oil, grease, tar, and stubborn deposits.

Lightly scratching the metal surface can improve adhesive adhesion. After scratching, clean the surface to remove loose debris.

For safety with extra heavy metal items or vertical/overhead bonding applications, we recommend using mechanical fixings alongside Adiseal for extra safety. Follow steps (1 to 6) mentioned above to get a good strong bond.


How to stick plastic to brick

When bonding plastic to brick, Adiseal creates a robust and enduring bond. Clean the plastic surface thoroughly to remove dirt, dust, oil, or grease before applying the adhesive. Lightly scratching the plastic surface can enhance adhesion by increasing the surface area, ensuring a stronger bond. Adiseal works well for bonding various plastic types to brick, like PVC, but isn’t compatible with materials such as polypropylene or polyethylene.

Follow the aforementioned steps (1 to 6) for the best outcome. Adiseal is also suitable for adhering artificial grass to brick surfaces.

How to bond stone, tile, masonry, ceramic & concrete to brick

To bond stone, tile, masonry, ceramic, and concrete to brick, follow the steps outlined above. However, due to the weight of these items, it’s more likely that temporary supports will be needed. Alternatively, the Adiseal Hi-Grab adhesive is a suitable option to avoid using temporary supports.

Adiseal is an effective adhesive for sticking various types of stone, including marble, granite, travertine, and slate, as well as many other types of stones.

For safety reasons on extra heavy stone, brick, tile or other masonry items, mechanical fixings also need to be used in conjunction with Adiseal when used on to bond items to vertical & overhead applications.




Glue for brick

It is also possible to glue to brick using our Adiglue product. However, it’s important to note that Adiglue is less flexible and not as strong as Adiseal construction adhesive and construction sealant.

To demonstrate the bonding strength of Adiglue on brick, we conducted tests by gluing bricks together and attaching MDF wood to the bricks. It’s essential to seal the bricks and MDF with Adiglue Activator before applying Adiglue to prevent them from absorbing the liquid adhesive. Unlike our construction adhesive Adiseal, sealing of porous materials like brick is necessary for Adiglue.

Glue brick and other items with Adiseal

Adiseal will successfully glue brick and the following materials together:



Exterior brick adhesive

Adiseal is an outstanding choice for an exterior brick adhesive, given its flexibility, UV resistance, and waterproof properties.

Pro tip: When there’s a possibility of water running behind the item, it’s advisable to apply the exterior brick adhesive in thin vertical strips. This allows water to run down rather than accumulating on top of the adhesive, which can freeze and expand in cold temperatures, exerting additional pressure on the adhesive.



Adiseal adhesive and sealant is available in the following colours:

Adiseal can also be manufactured in any RAL colour.

Mechanical fixings on brick

You can also attach items to brick using mechanical fixings by drilling into the brick. Our Adiseal Ultimate masonry drill bit and multi-material drill bit are exceptionally fast when used with a non-hammer function drill. In our test, drilling into brick with a basic non-hammer cordless drill, the Adiseal Ultimate masonry and multi-material drill bit drilled as fast as a corded SDS hammer drill. Notably, the SDS hammer drill ended up breaking the brick, a common issue with hammer drills.
