Best Practices for Using Jointing Mortar with AAC Blocks to Prevent Cracks

Do you know how to stop cracks when building with AAC blocks? The first and most important step is using the right AAC block jointing mortar. If the mortar is not applied correctly, the walls can become weak and develop cracks over time. That is why it is important to choose high-quality mortar from trusted AAC block jointing mortar manufacturers. 

In this blog, we will share simple and effective tips to prevent cracks using Dlite, one of the most reliable block jointing mortar manufacturers in India.

1. Choose the Right Mortar

Always choose mortar made especially for AAC blocks. Dlite is a trusted name among block jointing mortar manufacturers in India. Their mortar is made with the right materials for strong bonding and fewer cracks.

2. Mix the Mortar Properly

Take clean water and mix the mortar as per the instructions. The mix should not be too watery or too dry. A 3:1 water-to-mortar ratio is usually good. Stir well to make it smooth.

A good mix ensures that the aac block jointing mortar spreads well and bonds the blocks tightly.

3. Wet the AAC Blocks Correctly

Before applying the mortar, dampen the AAC blocks with water. This helps in better sticking. But do not use too much water. Over-wetting can cause weak joints. Many expert aac block jointing mortar manufacturers suggest just a light spray of water.

4. Apply a Thin Layer of Mortar

Use a thin layer of about 3-5mm only. A thick layer can cause shrinkage and cracks. Dlite aac block jointing mortar spreads easily and sticks well, even with a thin coat. Always start placing the blocks from the corners and then go toward the center of the wall.

5. Align and Level the Blocks

Make sure each AAC block is placed properly. They must be straight and even. Poor alignment can create pressure points, which may lead to cracks. Trusted block jointing mortar manufacturers in India like Dlite design their products to give good working time so you can adjust the blocks if needed.

6. Curing Is Important

After laying the blocks, curing the mortar joints is very important. Spray water lightly on the joints twice a day for 7 days. This keeps the mortar strong and prevents it from drying too fast, which can cause cracks.

Many top aac block jointing mortar manufacturers suggest curing for at least a week. Dlite products also perform best when cured properly.

7. Use Bond Beams and Control Joints

For better strength, you can add bond beams every 900-1200mm. These beams help reduce pressure on the walls. Also, use control joints to allow movement in the wall. These steps help reduce cracks, especially in big buildings.

If you are working with doors and windows, use mesh reinforcement around those areas. Brands like Dlite, trusted by many as one of the top block jointing mortar manufacturers in India, recommend these methods for safe construction.

8. Store the Mortar Well

Always store your aac block jointing mortar in a dry and cool place. Keep it away from sunlight and moisture. Wet mortar becomes useless and cannot be used. Dlite gives clear instructions on storage, so you get the best results every time.
