Spalling concrete is a common issue in older driveways, appearing as flaking or chipping surfaces that can detract from the aesthetic and integrity of your property. Addressing spalling is important to prevent tripping hazards and further deterioration. Here’s a step-by-step guide on how to fix spalling concrete in your driveway.
Materials and Tools Needed:
1. Pressure washer
2. Protective gear (gloves, safety glasses)
3. Concrete resurfacer
4. Trowel
5. Chisel and hammer (if needed)
6. Broom or brush
Step-by-Step Instructions:
1. Assess the Damage:
Begin by examining the extent of the spalling. If the damage is widespread, you may need to consider resurfacing the entire driveway rather than doing spot repairs.
2. Clean the Surface:
Use a pressure washer to thoroughly clean the driveway, removing dirt, debris, and loose concrete fragments. This ensures proper adhesion of the new surface material.
3. Remove Loose Concrete:
If there are any large loose pieces of concrete, use a chisel and hammer to remove them gently. Be cautious not to create additional damage to surrounding concrete.
4. Prep for Resurfacing:
Once the surface is clean and free of loose material, broom or brush off any remaining dust or particles. The driveway must be as clean as possible before applying any repair materials.
5. Mix the Concrete Resurfacer:
Follow the manufacturer’s instructions for mixing the concrete resurfacer. Make sure to wear protective gear including gloves and safety glasses during this process.
6. Apply the Resurfacer:
Pour a portion of the mixed resurfacer onto the damaged area and use a trowel to spread it evenly over the spalled sections, filling in all chips and flaked areas smoothly.
7. Finish the Surface:
Smooth out the resurfaced area with your trowel, ensuring it blends seamlessly with the rest of your driveway surface. Pay attention to edges and corners for a uniform finish.
8. Allow to Dry:
Let the resurfacer dry according to manufacturer recommendations before allowing foot traffic or vehicles onto the driveway. This typically ranges from 24-48 hours.
9. Seal the Surface (Optional):
For added protection against future spalling, consider applying a sealant once the concrete has fully cured and dried again as per instructions on sealant packaging.
By following these steps, you can effectively restore your driveway’s appearance and extend its lifespan by repairing spalling concrete efficiently and affordably.
