Glue for Brick

To glue different materials to brick, you need the right brick adhesive. With so many options available, how do you know which is the best brick adhesive? We’ll explain why Adiseal adhesive & sealant is the ultimate solution for bonding wood to brick, metal to brick, stone to brick, plastic to brick and more. It is suitable for both interior applications as well as an exterior brick adhesive.

Choosing the Right Adhesive on Brick – Why Strong Adhesion Matters

When gluing different materials to brick, not just any adhesive will do. While there are many options available, the key is to find an adhesive that creates a strong and lasting bond between the brick and the other material. This is particularly important if the item will be used outdoors, where the adhesive needs to remain flexible, UV resistant, and waterproof. Choosing the right brick adhesive is essential to achieving a secure and durable bond that will stand the test of time.

Why Adiseal is the best adhesive on brick

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 or brick does not require sealing prior to applying the adhesive.

Strongest in independent test

In an independent adhesive strength test conducted by Ultimate Handyman, Adiseal outperformed the competition by over 3 times. So much so, that the screws holding the test rig down began to rip out, forcing the test on Adiseal to be stopped. This speaks to the incredible strength of Adiseal, making it the ultimate choice for any project requiring a powerful adhesive that can withstand even the toughest conditions.

Instant Grab

Adiseal adhesive & sealant has high initial grab, but for even more initial gripping power, try Adiseal Hi-Grab adhesive. While the final bond strength of both construction adhesives is comparable, Adiseal Hi-Grab provides an extra-strong initial hold. In the example below, we’ve demonstrated the impressive initial grab of the Adiseal adhesive sealant on both dry and wet brick surfaces.

Adiseal Hi-Grab construction adhesive is the perfect solution when you need a reliable hold on vertical surfaces but don’t have time to use temporary supports. When items are stuck to a vertical surface, they tend to slide down until the adhesive dries, which can be time-consuming and labor-intensive. However, with Adiseal Hi-Grab’s instant grab feature, you can eliminate the need for temporary supports, saving both time and labor costs. This makes Adiseal Hi-Grab the ideal choice for any project that requires quick and easy adhesion on vertical surfaces.

When there’s no need for an extra high instant grab adhesive, we recommend using the standard Adiseal adhesive & sealant for bonding applications. While Adiseal Hi-Grab offers exceptional gripping power, it’s a much thicker product that requires a lot more force to push the items closer together. In situations where a regular adhesive will suffice, Adiseal adhesive & sealant provides an excellent bond with less force required for application. This makes it the perfect choice for bonding applications where a strong and reliable hold is needed, without the need for an instant grab feature.

Why Epoxy Adhesives May Not Be Ideal for Bonding to Brick

While epoxy adhesives can technically be used to bond items to brick, they may not provide the best or most durable results. Here are some of the issues you may encounter when using epoxy on brick:

  • Lack of flexibility: Epoxy adhesives are typically not very flexible, which means the bond may weaken over time due to changes in temperature and moisture. The expanding and contracting of items can put extra force on the adhesive, and if it’s not flexible, it can become brittle and eventually break. Wind can also cause cracks, further weakening the bond.
  • Mixing requirements: Epoxy adhesives come in two separate components that must be mixed together in the correct ratio and thoroughly blended for optimal adhesive properties. If this is not done correctly, the adhesive may not perform as expected.
  • Lower initial grab: Epoxy adhesives typically have lower initial grab than Adiseal, which means temporary supports may be required while the adhesive cures. This can add to the overall time and cost of the project due to extra labor.

Problems with mastic adhesives on brick

While mastic adhesives can be used to bond items to brick, they may not provide the best or most long-lasting bond. Some of the problems with mastic adhesives include:

  • Mastic adhesives provide a weak initial bond in the first place. A mastic adhesive might be suitable at sticking light items indoors but will fail at more heavy duty applications.
  • Another problem with mastic adhesives are they are not waterproof. This means they are not suitable for use where they might be exposed to water.
  • Mastic adhesives are not flexible meaning the already weak bond will become even weaker over time. As explained above this can happen due to temperature changes, moisture changes, vibration and wind.
  • Mastic adhesives also have a low initial grab. Temporary supports will be required until the adhesive dries. This increases time & labour cost.

Problems with contact adhesives on brick

It’s possible to bond light sheet materials with a contact adhesive but it won’t be suitable for more heavy duty applications. Other problems with contact adhesives include:

  • Temporary supports will more likely be required as contact adhesives have low initial grab.
  • Where the surface is not even, there will be gaps between the 2 materials that require bonding. As contact adhesives do not have good gap fill properties, they will not be able to fill the gap. This will leave places where there is no adhesive between the two materials. As a result the bond will be weak.
  • As bricks are porous, they will require sealing first to prevent it soaking up any wet contact adhesive before the adhesive dries.

How to attach wood to brick

If you want to attach wood to brick, Adiseal is a reliable adhesive that creates a strong and long-lasting bond for both interior and exterior applications. Follow these steps for best results:

Details of how to attach wood to brick.

  1. Clean surface

    Prior to applying the adhesive, it is vital to have clean surfaces where the adhesive will be applied between the wood to brick. Make sure both surfaces are free from any dust, grease, paint or any other dirt. Using a fine brush like a painting brush will help remove fine dust.

  2. Apply adhesive

    Apply Adiseal to one material. Try to cover as much surface area as possible to get the strongest bond.

  3. Push wood to brick

    Firmly push the wood to the brick, ensuring that it is aligned correctly.

  4. Temporary supports

    Although not always necessary, if the wood starts to slide away, use temporary supports until the adhesive dries.

When attaching wood to brick, it’s important to consider that wood can absorb moisture from the air and expand or contract. 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.

How to attach metal to brick

To stick metal to brick, Adiseal will provide a very strong, long lasting, flexible & waterproof bond. To get the strongest bond, it is vital to have clean surfaces where the adhesive will be applied to.

Oil can be applied to some metals to stop them from rusting. To get a good bond, this oil needs to be removed first before applying the adhesive. Adisolve is ideal at removing oil, grease, tar & many other stubborn deposits.

Additionally, scratching the surface of the metal can help the adhesive stick better. Be sure to clean the surface after scratching to remove any loose debris.

Follow steps 1 to 4 as shown above.

For safety reasons on extra heavy metal items, mechanical fixings also need to be used between metal to brick in conjunction with Adiseal when used to bond items to vertical & overhead applications.

How to stick plastic to brick

When it comes to attaching plastic to brick, Adiseal provides a strong and long-lasting bond. Before applying the adhesive, it’s important to clean the plastic surface thoroughly to remove any dirt, dust, oil, or grease. Scratching the surface of the plastic can also help to increase the surface area, resulting in a stronger bond. Adiseal is suitable for gluing most types of plastic to brick like PVC but it’s not suitable for plastics like polypropylene or polyethylene.

Follow steps 1 to 4 as shown above.

Adiseal is also suitable when used to glue artificial grass to brick.

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 showcase the bonding strength of Adiglue on brick, we’ve tested it by gluing bricks together and also attaching MDF wood to the bricks. Prior to applying Adiglue, it’s crucial to seal the bricks and MDF with Adiglue Activator to prevent them from soaking up the liquid glue. Sealing of the brick or other porous materials is not necessary with our construction adhesive Adiseal.

Glue to brick other items with Adiseal

Adiseal will successfully bond the following materials to brick:

Exterior brick adhesive

When it comes to attaching something to brick in exterior applications, you need an adhesive that can withstand the elements. Adiseal is an excellent choice for an exterior brick adhesive as it remains flexible, UV-resistant, and waterproof.

Pro tip: If there’s a chance of water running behind the item, it’s best to apply the exterior brick adhesive in thin vertical strips. This allows any water to run down instead of building up on top of the adhesive, which can freeze and expand in cold temperatures and put extra pressure on the adhesive.

Adiseal is available in the following colours:

It can also be manufactured in any RAL colour.
