Can You Cover or Resurface Exposed Aggregate Concrete?

Yes, you can cover exposed aggregate concrete — and in many cases, it’s a smart way to restore a tired surface without tearing it all up. Whether you want to remove surface roughness, fix imperfections, or modernise the look, there are reliable solutions available that don’t require full demolition.

Quick Summary

• Yes, exposed aggregate can be resurfaced or covered

• Honed concrete and overlay systems are the most common solutions

• Ideal for updating old, stained or uncomfortable finishes

• Preparation and sealing are essential for longevity

• A professional assessment ensures the right method is chosen

Why Cover Exposed Aggregate?

Exposed aggregate is durable, but it’s not always ideal long-term. Over time, it can become patchy, uncomfortable to walk on, or simply fall out of style. Common reasons people resurface include:

• Smoother surface needed (especially for kids and pool areas)

• Surface staining or deterioration

• Matching new landscaping or renovations

• Desire for a more modern, refined look

Instead of removing and repouring the slab, resurfacing gives new life to what’s already there.

Option 1: Hone the Existing Surface

Honed aggregate is a refined version of exposed aggregate. It uses the same decorative concrete mix but is mechanically ground down to create a flat, even, and safer finish — ideal for families and entertaining areas.

Benefits:

• Smooth underfoot and less abrasive

• Helps eliminate surface stains and marks

• Cost-effective and time-saving

• Non-slip finish available for pool surrounds

• No need for concrete removal or disposal

Option 2: Apply a Polished Concrete Overlay

If the existing surface is too rough, cracked, or uneven, a polished concrete overlay might be the better fit. This method involves applying a thin, cement-based layer (10–15mm) over the existing concrete to create a new surface.

Why choose this option:

• Smooth and modern result

• Ideal for covered outdoor and indoor areas

• Can be customised in colour and texture

• Less invasive than full demolition

Note: Overlay systems are not suitable for exposed outdoor areas without overhead protection.

What to Consider Before Resurfacing

Resurfacing exposed aggregate isn’t always straightforward. Here’s what to factor in before choosing a method:

• Slab condition: Cracking or lifting may need to be repaired first

• Drainage and levels: Make sure new heights don’t create water issues

• Slip resistance: Especially near pools or on sloped paths

• Aesthetic goals: Choose the right finish to suit your home

• Budget and timing: Honing is typically quicker and cheaper than overlays

We’ll inspect your surface and walk you through the best approach — no guesswork.

When Full Replacement is the Better Option

In some situations, resurfacing won’t solve the problem. You might need to remove and replace the concrete if:

• The slab is structurally unsound

• Water pools regularly due to incorrect falls

• You want a new shape, layout or feature that resurfacing can’t provide

In these cases, we’ll quote transparently and recommend the right mix from our exposed aggregate or liquid limestone options.

FAQs

Can you resurface exposed aggregate around a pool?
Yes, honed aggregate is a popular choice for pool surrounds due to its smooth, safe, and slip-resistant finish.

Is resurfacing cheaper than replacing concrete?
Generally, yes. You’ll save on demolition and disposal costs, and avoid pouring a whole new slab.

Can honed concrete be applied to old exposed aggregate?
Absolutely. As long as the surface is in good condition, honing is a practical and attractive option.

Does a concrete overlay last as long as fresh concrete?
When done correctly, overlays are very durable and can last many years, especially in protected areas.

Is DIY resurfacing a good idea?
Not usually. Honing and overlays require specialised tools, surface prep, and experience to ensure durability and evenness.
