Step-by-Step Guide to Installing AAC Blocks

Step 1: Surface Preparation

Begin with cleaning the surface thoroughly. Remove dust, debris, or loose particles. The base should be level and slightly damp before laying the blocks.

• Use a leveling tool to check the plinth.
• Mark the layout with string lines and chalk for alignment.
• Apply a thin layer of mortar (if needed) to create an even foundation.

Step 2: Mixing the Adhesive

For bonding AAC Blocks, use a ready-mix AAC adhesive or polymer-based PU Adhesive.

• Mix the adhesive in clean water (follow the manufacturer’s instructions).
• Stir well until you get a smooth, lump-free paste.
• Let it sit for a few minutes before application.

Step 3: Laying the First Layer

This is the most crucial step.

• Apply a 3-4 mm adhesive layer on the base using a notched trowel.
• Place the first AAC Block and tap gently with a rubber mallet.
• Check the level and alignment carefully. The first layer should be perfectly level in all directions.

Step 4: Installing Other Layers

Once the first layer is set:

• Apply adhesive both on the horizontal surface and vertical sides of the blocks.
• Maintain a running bond pattern (staggered joints) for better strength.
• Continue checking alignment with a plumb bob or spirit level after every 2-3 layers.
• Use a saw or cutter to shape blocks when needed for corners or fittings.

Step 5: Curing Process

Curing is essential for strength development.

• Lightly spray water on the block joints 2-3 times a day for at least 3-5 days.
• Avoid excessive water – AAC Blocks absorb moisture quickly.
• Ensure proper ventilation during curing to allow drying.

Step 6: Finishing Tips

After wall installation:

• Wait for the wall to dry completely before applying plaster.
• Use a polymer-based plaster for a smoother finish.
• Apply waterproofing where needed, especially for exterior walls.
• Use a putty coat before painting for better finish and longevity.

Common Mistakes to Avoid

Avoid these errors for successful AAC Block installation:

• Using regular cement mortar instead of specialized AAC adhesive.
• Skipping level checks — especially in the first layer.
• Not maintaining proper joint thickness (ideally 3-5 mm).
• Overusing water during curing.
• Inadequate surface preparation leading to weak bonding.

FAQs

Are AAC Blocks Waterproof?

AAC Blocks are water-resistant but not completely waterproof. Apply proper surface finishes for protection.

Can I use Normal Cement instead of Adhesive?

Not recommended. Adhesive ensures better bonding and reduces thickness

Is Skilled Labor Required for AAC Installation?

AAC Installation is easier than traditional bricks but trained workers ensure faster, error-free construction.
