The Problem of Low Cement Adhesion: Here Are Tips to Overcome It

In construction, the adhesive strength of cement is crucial to ensure a sturdy and durable building. If the cement's adhesive strength is weak, plaster can peel easily, plaster can fall off easily, or brickwork can become brittle. This problem is often encountered in the field, but don't worry—there are several ways to overcome it.

Causes of Poor Cement Adhesion

• Improper mixing → too much water makes the mixture runny and weak.
• Poor material quality → dirty sand or expired cement can affect adhesion.
• Improperly prepared surfaces → dusty, oily, or overly dry walls prevent the cement from sticking properly.
• Rushing work → an unevenly mixed mixture or hasty installation can reduce adhesion.

Tips for Overcoming Weak Cement Adhesion
1. Use Quality Cement
Make sure to use fresh, SNI-compliant cement (without clumps). Store the cement in a dry place to prevent damage.

2. Adjust the Mixture Composition
Use the appropriate mixture ratio. For plastering, for example, you can use 1:4 (1 part cement to 4 parts clean sand). Don't use too much water; just enough to make the mixture easy to work with.

3. Clean the Surface Before Working
Wet the wall or brick surface before plastering to prevent it from absorbing too much water.

Remove dust, dirt, or oil so the cement can adhere properly.

4. Mix Thoroughly
A homogeneous mixture ensures the cement, sand, and water are thoroughly mixed, resulting in stronger adhesion.

5. Use Additional Materials If Necessary
Some projects add admixtures or bonding agents to improve adhesion, especially during renovations or repairs.

6. Perform Post-Work Maintenance
The plaster or plaster must be kept moist by watering it periodically for at least 3–7 days to prevent cracking.

Conclusion
Weak cement adhesion is usually caused by mixing errors, material quality, or poorly prepared surfaces. By paying attention to composition, material quality, and processing techniques, cement's adhesive strength can be improved, resulting in stronger and more durable buildings.
