Introduction
Concrete patios are strong and durable, but they’re not indestructible. Over time, weather, heavy use, or settling soil can cause holes, chips, or pits to form. Learning how to patch holes in a concrete patio will restore your surface, prevent further deterioration, and keep your outdoor space looking neat and safe. Many homeowners assume damaged patios require costly replacement, but most holes can be repaired quickly with the right materials and techniques.
Why Patching Holes Matters for Your Patio
Even small holes in a concrete patio should be repaired promptly:
- Prevents Water Damage: Holes allow rainwater to seep in, freeze, and expand, worsening cracks.
- Safety Hazard: Holes can create tripping risks for children, pets, and guests.
- Stops Weed Growth: Soil-filled holes are a perfect place for weeds to sprout.
- Improves Appearance: A patched patio looks cleaner and more inviting.
- Extends Lifespan: Routine patching avoids the need for full replacement.
Repairing holes is a simple, cost-effective way to protect your investment.
Step-by-Step Guide to Patching Holes in a Concrete Patio
Step 1: Assess the Damage
Determine the size and depth of the hole:
- Shallow holes (under ½ inch deep): Can usually be patched with resurfacer or filler.
- Deeper holes (over ½ inch): Require patching compound or concrete mix.
- Extensive damage: If the patio has multiple large holes, resurfacing or replacement may be needed.
Step 2: Gather Tools and Materials
You’ll need:
- Wire brush and broom.
- Chisel and hammer.
- Pressure washer or hose.
- Concrete patch compound or repair mortar.
- Mixing bucket and trowel.
- Putty knife for small holes.
- Safety gloves and goggles.
Step 3: Clean the Hole Thoroughly
Use a wire brush or chisel to remove loose concrete, dirt, or debris. Rinse with a hose or pressure washer and let the area dry slightly. Clean surfaces ensure the patch bonds properly.
Step 4: Undercut the Hole Edges
For larger holes, use a hammer and chisel to slightly widen the bottom of the hole compared to the top. This creates a “keyhole” shape that locks the patch in place.
Step 5: Dampen the Area
Lightly mist the hole with water before applying patching material. A damp surface helps the new compound adhere better, but avoid leaving standing water.
Step 6: Mix the Patching Compound
Follow manufacturer instructions to mix repair mortar, vinyl patching compound, or concrete resurfacer. Mix until smooth and lump-free. For deep holes, use a thicker patch mix; for shallow pits, use a thin resurfacer.
Step 7: Apply the Patch
- For small holes: Fill with patching compound using a putty knife. Smooth level with the surrounding concrete.
- For larger holes: Use a trowel to press the compound firmly into the cavity, building in layers if necessary. Compact each layer to remove air pockets.
Step 8: Smooth and Blend the Surface
Feather the patch edges outward to blend with the patio surface. Use a steel trowel for a smooth finish or a broom for a textured finish that matches the surrounding concrete.
Step 9: Allow to Cure Properly
Follow curing instructions on the product label. Most concrete patches require 24–48 hours to set. Keep the area damp during curing by misting with water or covering with plastic sheeting to prevent cracking.
Step 10: Seal the Patio
Once the patch is fully cured, apply a concrete sealer over the entire patio. Sealing protects against moisture, stains, and future damage while giving the surface a uniform look.
Common Mistakes to Avoid
- Mistake: Skipping Surface Prep
Applying patch over dirt or loose concrete leads to failure.
Solution: Always clean and undercut before patching. - Mistake: Using the Wrong Material
Ordinary mortar may not adhere to concrete properly.
Solution: Use a concrete-specific patch compound or resurfacer. - Mistake: Overfilling the Hole
Patches that sit above the surface will chip off.
Solution: Smooth flush with surrounding concrete. - Mistake: Not Curing Correctly
Allowing patches to dry too quickly causes cracks.
Solution: Keep moist and protect from direct sun while curing. - Mistake: Ignoring Sealant
Unsealed patches absorb water and fail faster.
Solution: Always apply sealer after repairs.
Extra Patio & Deck Tips & Hacks
- Quick DIY Patch: For very small holes, mix cement with water into a paste and press into place as a short-term fix.
