Adiseal Adhesive & Sealant vs Adiseal Hi-Grab
Adiseal Hi-Grab excels in gap-filling compared to standard Adiseal. If you don’t require strong initial grip or temporary supports, standard Adiseal is recommended for enhanced bonding. Standard Adiseal allows surfaces to be pressed together more easily, as Adiseal Hi-Grab’s thicker consistency requires more force for the same result. A high-quality sealant gun is necessary for dispensing Adiseal Hi-Grab due to its extra-thick formulation.
How to attach wood to concrete
How to attach wood to concrete
- Reduce gap
To achieve a strong adhesive bond, it is important to 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.
- Prepare the surfaces
Ensure that both the wood and concrete surfaces are clean, dry, and free from dust, debris, and any loose material. This will help create a strong bond. We recommend brushing the concrete with a fine brush like a painting brush to remove fine dust.
- Apply the adhesive
Apply a generous amount of adhesive onto the wood surface that will come in contact with the concrete. Use a notched trowel or a sealant gun to spread the adhesive evenly, covering the entire area where the wood will be attached.
- Position the wood
Carefully position the wood onto the adhesive, aligning it with the desired location on the concrete. Apply firm and even pressure to ensure good contact between the wood and the concrete surface.
- Secure the wood temporarily (optional)
If needed, use clamps or other temporary supports to hold the wood in place while the adhesive cures. This can be helpful for larger or heavier wood pieces.
- Allow the adhesive to cure
Follow the manufacturer’s instructions regarding curing time. 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. 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.
Cleaning concrete surface before applying the adhesive
For a high-quality bond, clean surfaces are essential. Dust or dirt can compromise the bond, particularly with concrete surfaces outdoors.
For effective concrete cleaning, consider options like jet washing or sandblasting for optimal results. Alternatively, use a mixture of water and suitable detergent with a stiff brush, but note that jet washing is more thorough. After using detergent, ensure a thorough rinse to remove any residue before applying the adhesive. To eliminate fine dust, you can use a vacuum, blower, or a fine brush, like a paintbrush. This preparation step is vital for a strong bond.
Concrete demonstration block
On our concrete demonstration block above, no primer or sealer was used before applying Adiseal concrete adhesive. The concrete was simply cleaned thoroughly before applying the adhesive.
How to bond metal to concrete
When bonding metal to concrete, Adiseal is the ideal adhesive for both indoor and outdoor use. Proper surface preparation is crucial for a strong bond.
Remove any oil applied to the metal to prevent rusting before applying the adhesive. Adisolve is effective at removing stubborn deposits like oil, grease, and tar.
For a good quality bond, lightly scratch the metal surface where the adhesive will be applied (not always necessary). This increases surface area and improves adhesion. Sandpaper or a file can be used. Clean the surface thoroughly afterward to remove loose metal particles.
Apply the adhesive between the metal and concrete, pressing them together firmly. Temporary supports may be needed if the items tend to slide. Adiseal Hi-Grab adhesive has higher initial grab, reducing the need for temporary supports in many cases.
How to bond plastic to concrete
Adiseal is suitable for bonding most plastics to concrete, except for polypropylene and polyethylene.
Before applying the adhesive, thoroughly clean the plastic to remove dust, oil, grease, paint, or any other dirt. Increasing the surface area by scratching the plastic enhances the bond strength between the plastic and concrete.
Apply the adhesive and firmly press the plastic onto the concrete surface to ensure proper contact and a strong bond.
Adiseal is also an excellent choice for gluing artificial grass to concrete surfaces, offering reliable and long-lasting adhesion for landscaping projects or outdoor areas.
How to bond stone, brick, tile or masonry to concrete
When bonding stone, brick, tile, or masonry to concrete, Adiseal is the ideal adhesive for both indoor and outdoor use. Proper surface preparation is crucial for a strong and durable bond.
Thoroughly brush off any dust before applying the adhesive. Priming the stone, brick, or masonry surface is usually unnecessary with Adiseal as long as the surfaces are clean.
Unlike other adhesives or glues, Adiseal avoids bleeding into porous stone materials, solving a common problem.
For bonding, ensure both surfaces are completely clean, especially from loose bits and dust. Apply the adhesive to one surface and firmly press the item onto the concrete. If sliding occurs, temporary supports may be needed.
Consider using Adiseal Hi-Grab adhesive for heavier stone, brick, tile, or masonry items. It provides a higher initial grab, reducing the need for temporary supports until the adhesive cures.
Adiseal is highly effective for bonding various stone types, including marble, granite, travertine, slate, ceramic, and more.
For added safety, when bonding extra heavy stone, brick, tile, or masonry items, it is recommended to use mechanical fixings in conjunction with Adiseal, especially for vertical and overhead applications. This ensures maximum stability and strength.
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.
For example, we successfully glued a metal handle to a heavy concrete slab using Adiglue. Before applying Adiglue, it’s important to seal the concrete surface with Adiglue Activator to prevent absorption. However, when using Adiseal construction adhesive and sealant for the same purpose, sealing is not required.
Glue for concrete vs concrete adhesive
Whether a glue for concrete is better to use or an adhesive depends on the type of job and the surface area available for the bond between 2 materials.
Small jobs
If you have to bond to concrete items with a small surface area then Adiglue is the better product.
Large jobs
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.
Bonding other items to concrete with Adiseal
Cement adhesive
Concrete and cement are two related but distinct materials used in construction. Here is the difference between them:
Cement: Cement is a powdered binding material made from a mixture of limestone, clay, shells, silica, and other materials. It acts as a binder that binds the ingredients together to form a solid mass. Cement is a crucial component in concrete, but it is not concrete itself. There are different types of cement, such as Portland cement, which is commonly used in construction.
Concrete: Concrete is a composite material composed of cement, aggregates (such as sand and gravel or crushed stone), and water. The aggregates provide strength and stability to the concrete mixture, while water activates the cement and facilitates the chemical reaction known as hydration. Upon curing, the mixture hardens and forms a solid structure. Concrete is a versatile material widely used in construction for foundations, walls, floors, pavements, and various structures.
In summary, cement is an ingredient used to make concrete. It is the binding agent that holds the aggregates together. Concrete, on the other hand, is a mixture of cement, aggregates, and water, which forms a strong and durable construction material.
Mechanical fixings
It is also possible to attached items to concrete by using mechanical fixings. 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.
