Concrete resurfacing is a cost-effective way to rejuvenate old, worn, or damaged concrete surfaces without the need for complete replacement. Whether you’re dealing with cracks, stains, or surface deterioration, resurfacing offers a fresh, durable layer that improves both appearance and performance.
In this guide, we’ll walk you through the full process of concrete resurfacing—perfect for homeowners in Palmerston North looking to extend the life of their driveways, patios, or paths.
What is Concrete Resurfacing?
Concrete resurfacing involves applying a thin layer of cement-based overlay over existing concrete. This overlay bonds to the old surface and provides a new, uniform look. It can be left plain or textured and coloured for decorative effect.
When Should You Resurface Concrete?
Ideal Conditions for Resurfacing:
- Surface is structurally sound
- Minor cracks, stains, or surface wear
- Discolouration or cosmetic imperfections
When Not to Resurface:
- Deep cracks or severe structural damage
- Heavily heaved or sunken slabs
- Crumbling concrete with poor base support
In these cases, slab replacement or significant repair may be needed first.
Step-by-Step Resurfacing Process
Step 1: Inspect and Assess the Surface
Before starting, assess whether the concrete is suitable for resurfacing.
- Check for cracks, spalling, or uneven settling
- Tap the surface to listen for hollow spots
- Ensure there is no active moisture problem or ground movement
Step 2: Clean the Surface Thoroughly
Proper surface preparation is critical for a long-lasting bond.
- Sweep and hose down the area
- Use a pressure washer to remove dirt, grime, oil, or algae
- Degrease oily spots using concrete cleaner or degreaser
- Remove any loose or flaking material with a scraper or grinder
Step 3: Repair Any Minor Damage
Fill in cracks or holes before applying the resurfacer.
- Use a patching compound or crack filler suitable for concrete
- Allow repairs to cure according to product instructions
Step 4: Prepare the Resurfacing Mix
Use a high-quality concrete resurfacing compound.
- Mix as per manufacturer instructions (usually with a drill mixer)
- Ensure the consistency is smooth and lump-free
- Mix only what can be applied within 30 minutes to avoid drying in the bucket
Step 5: Apply the Bonding Agent (if needed)
Some resurfacing products require a primer or bonding agent.
- Apply using a roller or brush
- Follow dry or wet bond instructions as directed
Step 6: Pour and Spread the Resurfacer
Start from one end and work in sections.
- Pour resurfacer onto the surface in strips
- Use a trowel, squeegee, or gauge rake to spread evenly
- Maintain consistent thickness (usually 3–6 mm)
Step 7: Add Texture (Optional)
For driveways and walkways, apply a non-slip finish.
- Use a broom for a textured surface
- Apply decorative stamps or patterns while the material is still pliable
Step 8: Cure and Seal the Surface
Allow the resurfaced area to cure properly.
- Keep surface moist for the first 24–48 hours if needed
- Avoid foot traffic for at least 6–8 hours
- Avoid vehicle traffic for 2–3 days
- After full cure, apply a penetrating concrete sealer
