STEP 1 – MIX THE MORTAR

In a clean bucket, add 3 parts AdheXcel AAC Block Mortar to 1 part clean water (20–25% by volume).
Mix for 3–5 minutes using a hand tool or an electric mixer.

STEP 2 – ALLOW TO STAND

Let the mixture rest for 3–5 minutes, then remix for 1–2 minutes until smooth and lump-free before use.

STEP 3 – PREPARE THE SURFACE

Clean the AAC block surfaces using a brush to remove dust and loose particles.

STEP 4 – DAMPEN THE SURFACE

Moisten the block surfaces with water before applying mortar to improve adhesion.

STEP 5 – APPLY MORTAR EVENLY

Spread the mortar evenly on all sides of the block using a notched trowel.
Maintain a consistent bond thickness of 3–5 mm.

STEP 6 – PLACE THE BLOCKS

Place the blocks with minimal displacement.
Tap gently using a rubber or fiber hammer to remove air gaps and ensure proper alignment.

STEP 7 – CHECK LEVEL & ALIGNMENT

Use a spirit level or tie/rope method to check both horizontal and vertical alignment.
Make adjustments before the mortar begins to set.

STEP 8 – ALLOW TO SET

Do not disturb or dismantle the constructed wall for at least 24 hours.
Setting time may vary depending on weather and site conditions.
