Adiseal Adhesive Sealant vs. Adiseal Hi-Grab
While both products offer the same record-breaking final bond strength, choosing the right version depends on your specific brick bonding project:
- Adiseal (Standard): Best for applications where you need to move or “slide” the item into the perfect position before it sets. It has high gap-fill and is the best choice for general brick bonding.
- Adiseal Hi-Grab: Best for heavy vertical items (like large stone wall claddings or heavy signs). It provides instant suction, usually eliminating the need for temporary supports or shoring while the adhesive cures.
Where To Buy
Instant Grab Adhesive For Brick Bonding
When attempting to bond brick, 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 brick 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.
- Prepare the Surfaces
Clean both wood and brick surfaces thoroughly. Use a clean cloth or a stiff painting brush to remove all dust, dirt, and loose particles.
- Apply the Adhesive
Apply enough Adiseal to create a solid bond. Avoid excessive amounts that might squeeze out from the edges when pressure is applied.
- Position the Wood on the Brick
Align the wood onto the brick and apply firm, even pressure to ensure maximum contact between the surfaces.
- Secure the Wood
If bonding heavy wood, use clamps or temporary supports to prevent sliding or shifting while the adhesive cures.
- Remove Excess Adhesive
Use a putty knife or damp cloth to wipe away any adhesive that squeezes out before it fully cures.
- Allow Sufficient Curing Time
Refer to the manufacturer’s instructions for curing times. Avoid putting stress on the bond during this period.
Important Safety Tips
Storage Tip: To store Adiseal after opening, leave 1cm of product protruding from the nozzle and store the tube upright. The exposed part will cure into a protective cap; simply pull it out when you’re ready to use it again.
Handle Thermal Expansion: Wood naturally expands and contracts. Using a flexible adhesive like Adiseal is essential to prevent the bond from snapping over time.
Heavy Duty Applications: For extra heavy wood in vertical or overhead positions, we recommend using mechanical fixings in conjunction with Adiseal for maximum safety.
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 brick with various plastic 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 bonding, 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.
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.
What Materials Will Adiseal Stick To Brick?
Adiseal is a universal MS polymer engineered to bond virtually most materials. It replaces the need for specialized wood glues, masonry adhesives, and plastic sealants.
| Surface Category | Compatible Materials | Professional Application |
|---|---|---|
| Masonry & Stone | Concrete, Brick, Granite, Marble, Slate, Limestone, Travertine | Ideal for paving, wall capping, and non-staining stone cladding. |
| Metals | Steel, Aluminum, Lead, Copper, Iron, Zinc | Perfect for gutter repairs, flashing, and structural metal-to-concrete bonding. |
| Plastics & Synthetics | PVC, ABS, Polycarbonate, Fiberglass, GRP, Polystyrene | Used for roofing sheets, window frames, and plumbing fixtures. |
| Wood & Timber | Hardwood, Softwood, MDF, Plywood, Chipboard | Provides a waterproof bond that won’t rot or weaken in damp environments. |
| Glass & Ceramics | Clear Glass, Mirrors, Porcelain, Tiles, Quartz | Securely bonds mirrors (non-corrosive) and kitchen/bathroom tiles. |
| Roofing Materials | Felt, Asphalt, EPDM, Bitumen, Shingles, Rubber (natural) | Instant emergency leak repair on major roofing substrates. |
Why Adiseal Bonds Better to Different Materials:
- Non-Porous Excellence: Unlike water-based adhesives, Adiseal cures via atmospheric moisture, allowing it to bond two non-porous surfaces (like metal to glass) effectively.
- Anti-Stain Technology: Many adhesives “bleed” oils into stone or marble. Adiseal’s chemically inert formula ensures zero migration into porous materials.
- Vibration Resistance: On materials prone to movement (like metal roofing or wood floors), Adiseal acts as a shock absorber, maintaining the bond during thermal expansion.
While Adiseal can bond to Bakelite, its smooth surface may require sanding with fine-grit sandpaper to create a mechanical “key” for the adhesive. This is recommended for all smooth surface materials.
What materials does it not work on?
While Adiseal adhesive sealant is highly versatile, it does not adhere well to low surface energy (LSE) plastics like polypropylene (PP), polyethylene (PE), and polytetrafluoroethylene (PTFE/Teflon).
Key Materials to Avoid:
- LSE Plastics: Polypropylene (PP), Polyethylene (PE), Nylon (Polyamide) and Polythene.
- Non-Stick Surfaces: PTFE (Teflon).
- Contaminants: Asphalt, oils, and existing silicone residue.
- Incompatible Adhesives: Uncured polyurethane or silicone-based products.
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.
Colours
Adiseal adhesive and sealant is available in the following colours:
- White adhesive and white sealant
- Black adhesive and black sealant
- Grey adhesive and grey sealant
- Clear adhesive and clear sealant
- Brown adhesive and brown sealant
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.
