Expert Tips for Effective Crack Repair in Walls Using PPC Cement

Wall cracks is a common issue in homes and buildings,  affecting both aesthetics and structural integrity. While many homeowners opt for quick fixes, using the right material and techniques is crucial for long-lasting repairs. This is where Portland Pozzolana Cement (PPC) comes in as a durable and effective solution for wall crack repair.

Understanding PPC Cement

PPC cement is a blend of ordinary Portland cement and pozzolana (a naturally occurring or industrial by-product). This combination creates a cement that is stronger, more durable and more resistant to water penetration than traditional grey cement.

Identifying the Cause of Wall Cracks

Before starting repairs, it's essential to identify the underlying cause of the cracks. This will help you in selecting the appropriate repair method and prevent future damage. Common causes include:

• Settlement: As buildings age, the ground beneath them can settle, leading to cracks.
• Moisture: Excessive moisture can cause walls to expand and contract, resulting in cracks.
• Structural issues: Structural problems, such as foundation issues, can also cause cracks.

Preparing the Area for Repair

1. Clean the crack: Remove any loose debris, dirt or paint from the crack using a wire brush or putty knife.
2. Widen the crack: If necessary, widen the crack slightly to ensure proper penetration of the repair material.
3. Prime the area: Apply a primer to the cracked area to improve adhesion and prevent moisture penetration.

Mixing PPC Cement for Wall Repair

1. Gather materials: Arrange PPC cement, sand, water and a mixing container.
2. Determine the mix ratio: The ideal mix ratio for wall repair can vary based on the crack's size and severity. It’s recommended to adhere to the PPC cement manufacturer's guidelines or consult a construction professional for recommendations.
3. Mix the cement: Combine PPC cement, sand and water in the recommended proportions thoroughly until you achieve a smooth and workable consistency.

Process for Applying PPC Cement to Cracks

1. Fill the crack: Use a putty knife or trowel to apply the PPC cement mixture to the crack, ensuring it is slightly overfilled.
2. Smooth the surface: Smooth the repaired area to match the surrounding wall surface.
3. Allow to dry: Let the PPC cement dry completely before applying a finishing coat.

Finishing the Repair

1. Sand the area: If needed, sand the repaired area to ensure a smooth finish.
2. Apply a finishing coat: Apply a finishing coat of paint or plaster to match the surrounding wall.
