What You'll Learn
Clean the brick and plastic surfaces
Before sticking plastic to brick, it is essential to prepare the surfaces by cleaning, roughening, and priming them. This process ensures that the adhesive will effectively bond the plastic to the brick and results in a durable and reliable final product.
To clean the brick surface, use a rag or broom to wipe away any dust or debris. If there is finer dust on the brick, use a paintbrush to sweep it away. You want to ensure that you are sticking the plastic to the brick itself, not to any dust or dirt that has settled on the surface.
Similarly, clean the plastic surface with a rag to remove any dirt, dust, oil, or grease. You can also use a product like Adisolve to eliminate any oil, grease, or stubborn deposits.
Once the surfaces are clean, you can enhance the adhesion by lightly scratching the plastic surface with a tool like a knife. This increases the surface area available for bonding and ensures a stronger final hold. Just be sure to clean the surface again after scratching to remove any loose debris.
After cleaning and lightly scratching the surfaces, you can move on to the next step of priming the surfaces. Priming the surfaces involves roughening them slightly to improve the bond. This can be done by scoring the surfaces with a tool like a knife or sandpaper.

Roughen the surfaces
Roughening the surfaces of both the plastic and the brick is an important step in preparing them for adhesion. This process helps to improve the bond between the two materials. The plastic surface can be lightly scratched to increase the surface area and enhance adhesion, resulting in a stronger bond. This is especially important for plastic because, as a non-porous and smooth material, it can be challenging for adhesives to form a strong bond.
Similarly, brick surfaces are porous and uneven, providing ample surface area for adhesion. However, their irregular texture can pose challenges. By roughening the brick surface slightly, you can increase the contact area and improve the overall adhesion.
When roughening the surfaces, it is important to be cautious and not create excessive scratches or damage to the materials. A gentle approach is best, using appropriate tools or abrasives to create a slightly roughened texture without causing any significant damage.
The specific type of plastic and the composition of the brick should also be considered during this process. Different types of plastics, such as polyethylene, polypropylene, or PVC, may require different levels of surface roughness to achieve optimal adhesion.
Overall, roughening the surfaces is a crucial step in preparing plastic and brick for adhesion. It helps improve the bond strength and ensures a more durable and reliable connection between the two materials.

Choose a strong adhesive
When it comes to choosing an adhesive to stick plastic to brick, you need to select a strong construction adhesive designed for both plastic and masonry surfaces. The specific type of plastic you are working with will influence the adhesive formulation required for optimal bonding. For instance, Adiseal works well for bonding brick with PVC, but it is not compatible with polyethylene or polypropylene.
Before applying the adhesive, it is crucial to prepare the surfaces by cleaning them thoroughly to remove any dirt, dust, or debris. You can use a rag or a broom to clean the brick surface. Additionally, roughening the surfaces can improve the bond. This can be achieved by lightly scratching the plastic surface to increase the surface area, which will result in a stronger bond.
For a temporary solution, hot glue can be used, but it is important to note that it may leave residue on the brick pores. Exterior mounting tape, such as 3M Extreme mounting tape, can also be considered for temporary applications, but it may leave visible residue.
If you are looking for a permanent solution, a specialised adhesive designed to bond plastic and brick is necessary. Universal adhesives, which bond rigid materials together regardless of surface evenness, can be used for small repairs. However, for larger applications, it is recommended to use an adhesive like Adiseal, which provides a high-strength, flexible, and durable bond.

Apply a thin layer of glue
To stick plastic to brick, you will need to apply a thin layer of glue. However, before you do so, it is important to prepare the surfaces of both the plastic and the brick. Start by cleaning them thoroughly to remove any dirt, dust, or debris. You can use a rag or a broom to clean the brick, and for the plastic, ensure you wipe down with a cloth to remove any dust or grease.
Next, you should roughen the surfaces slightly. For the plastic, you can lightly scratch the surface to increase the surface area and improve adhesion. As for the brick, its naturally porous and uneven texture already provides ample surface area for adhesion. However, you can also use a brush to gently scrape the surface to create more texture.
Now, you are ready to apply the adhesive. Choose a strong construction adhesive designed for use on both plastic and masonry surfaces. Look for adhesives labelled for specific types of plastic, such as PVC, polyethylene, or polypropylene, to ensure optimal bonding. Adiseal, for instance, works well for bonding brick with PVC but is not suitable for polypropylene or polyethylene.
With your chosen adhesive, start by applying a thin layer of glue to the brick surface. Gently squeeze the glue bottle over the brick, ensuring an even spread. A thin layer is more effective than a thick one, as it allows for a stronger bond.
After applying the glue, quickly proceed to the next step of attaching the plastic to the glued brick surface. Hold the plastic firmly and evenly against the brick for at least 30 seconds. You may also want to use a clamp to keep the plastic in place while the glue dries. The glue will continue to dry and strengthen over several hours, creating a resilient and enduring bond.
By following these steps and choosing the right adhesive, you can successfully stick plastic to brick, creating a strong and durable bond.

Use clamps to hold the plastic in place
When adhering plastic to brick, it is important to use clamps to hold the plastic in place while the adhesive cures. This will ensure that the plastic does not slide or shift, resulting in a strong and durable bond.
Before clamping, it is crucial to prepare both the plastic and brick surfaces. Start by cleaning the surfaces thoroughly to remove any dirt, dust, grease, or debris. You can use a clean cloth, brush, or broom to wipe down the surfaces and ensure they are free of any contaminants. For finer dust particles, a painting brush can be useful.
Additionally, it is recommended to roughen or lightly scratch the surfaces to improve the adhesion. This can be done by lightly scratching the surfaces with a tool or sandpaper. By creating a slightly rough texture, the adhesive will have more surface area to bond with, resulting in a stronger hold.
Once the surfaces are prepared, apply a suitable adhesive designed for use on both plastic and masonry surfaces. Choose an adhesive that is strong and durable, such as a construction adhesive or a specialised adhesive like Adiseal, which is known for its robust and enduring bond. Spread a thin layer of adhesive onto the brick surface, ensuring complete coverage of the area where the plastic will be attached.
Now, carefully position the plastic onto the brick, applying firm and even pressure to establish good contact between the two surfaces. Finally, use clamps to hold the plastic securely in place while the adhesive cures. Open the clamps, place them over both the brick and plastic, and then tighten them to ensure a firm hold.
By following these steps and using clamps to hold the plastic in place, you can be confident that your project will result in a resilient and enduring bond between the plastic and brick surfaces.
