How does Jointing Mortar Help AAC Blocks Stick Together

In an accelerating world of construction, AAC (Autoclaved Aerated Concrete) blocks have rapidly emerged as preferred products for builders, architects, and homeowners alike. It’s easy to see why — they deliver lightweight, energy-efficient, and sustainable solutions. However, to take full advantage of the benefits that AAC blocks offer, the right adhesive is needed to secure them in place.

That’s where NCL Masonry Glue fits in — and it makes all the difference.

How Traditional Mortar Now Falls Short

For generations, construction has routinely relied on cement-sand mortar, but this rigid, inconsistent, and inaccurate practice no longer stands up in the face of AAC blocks. NCL Buildtek recognised this problem and proactively provided a smarter solution in the form of a ready-mix, polymer-modified jointing mortar that’s designed to account for AAC block work in its development stages.

It’s fair to say that NCL Masonry Glue will ensure a cleaner working environment, stronger walls, and quicker advancements on site.

Why NCL Masonry Glue Is So Effective?

  • Outstanding Bonding Strength: It keeps each AAC block in position, thus minimising the chance of cracks and keeping the building together for years to come.
  • Quite Thin – But Quite Strong Joints: You only need a 3 – 4 mm thickness; that is an awful lot less material, a hell of a lot more insulation.
  • No fuss, No Mess: Mix it with water and apply with a notched trowel.
  • No Water Curing: It is self-curing! That saves time and means you don’t have to fuss about.
  • You will Always Have the Same Quality: It is made under very tight controls in a factory, therefore you know exactly what you are getting, batch after batch after batch.

Simple to Apply, Strong Results

Before you start, make sure that the AAC blocks are clean and slightly moist. Mix the glue according to the instructions, piece on a small amount on the block surface. Put the next block into position, aligning the blocks as needed to minimise movement of the adjacent block and you are ready to go.

When constructing with AAC blocks, don’t let the wrong mortar restrict you. NCL Masonry Glue provides a jointing product that is quick, clean and durable – just like your construction. Strong walls are more than just good materials; they are made from the right combination of innovation, reliability, and trust, and NCL Buildtek deliver exactly this.
