How to use a masonry adhesive

 How to use a masonry adhesive

  1. Surface Preparation

    Ensure that the surfaces to be bonded are clean, dry, and free from dust, debris, or any loose material. Use a wire brush or similar tool to remove any loose particles. Using a fine brush like a painting brush will help remove fine dust.

  2. Adhesive Application

    Apply the masonry adhesive to one of the surfaces using the appropriate method. Covering more surface area with an adhesive can provide a better bond.

  3. Bonding Surfaces

    Press the surfaces firmly together, ensuring proper alignment and contact. Apply sufficient pressure to create a strong bond. Adjust and reposition if necessary before the adhesive starts to set. Sliding the item side to side slightly can help spread the adhesive to cover more surface area.

  4. Temporary supports

    Use temporary supports if the item does not stay in place until the adhesive has cured.

  5. Curing Time

    Allow the adhesive to cure according to the manufacturer’s instructions. This typically involves a specified time for the adhesive to reach its full strength. Avoid disturbing or applying stress to the bonded surfaces during the curing process.

  6. Cleanup

    Clean any excess adhesive immediately using a damp cloth or the recommended solvent, following the adhesive manufacturer’s instructions. It is easier to remove the adhesive before it fully cures.

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.

Masonry adhesive or masonary adhesive

“Masonry” is a term that is often misspelled as “masonary.” However, it is important to note that the correct spelling is masonry. The misspelling masonary may be a common error due to the similarity in pronunciation, but it is not the proper spelling of the word. Masonry refers to the construction or craft of building structures using bricks, stones, concrete blocks, or other similar materials. So when people are talking about masonary adhesive, what they actually mean is masonry adhesive.

Glue for Masonry

Masonry glue is specially designed for robust and lasting bonds in tasks involving bricks, stones, concrete blocks, and similar materials. It’s often used in construction for tasks like securing masonry veneers, repairing cracks or gaps in masonry structures, and assembling masonry elements.

Glue demonstration on bricks and wood.

Masonry glue is designed to endure significant loads and stresses prevalent in masonry projects. Its weather-resistant properties guarantee reliable and enduring bonds, making it suitable for various outdoor applications.

To ensure effective bonding, it is vital to prepare surfaces by thoroughly cleaning them of dust, debris, and loose materials. Apply the glue evenly, ensuring adequate coverage. Press the masonry materials together, allowing the glue to bond and set. Curing times may vary based on the product and environmental conditions, so following the manufacturer’s instructions is crucial for optimal results.

Adiglue glue for masonry

When using Adiglue glue on masonry, to avoid the masonry soaking up the glue, seal the masonry first before applying the glue.

Adiglue glue for masonry and other items

For most bonding applications is is advisable to use the Adiseal adhesive and sealant over the Adiglue product. Adiseal adhesive and sealant will provide a stronger, more flexible and more durable bond on masonry.

Mechanical fixings

It’s also possible to attach items to masonry with mechanical fixings by drilling masonry first. Our Adiseal Ultimate masonry drill bit & multi material drill bit drills faster than any other bit when drilling without hammer function on drill. It is suitable at drilling brick, drill concrete, wood, plastic and other building materials.
