Concrete Pool Surrounds: Choosing a Finish That's Safe Underfoot

Around a pool the finish matters more than the concrete under it. It has to stay grippy when it's wet, not cook bare feet on a 38 degree January day, and handle chlorine splashing out of the pool without staining or breaking down.

Get the finish right and nobody thinks about it again. Get it wrong and you've got a surface people slip on, or one the kids won't walk on barefoot, and that's not something you fix with a mop.

Slip resistance comes first

A smooth trowel finish looks great in a photo and is the wrong call around water. Wet smooth concrete is genuinely slippery, and a pool surround is wet most of the time it's being used.

So everything we'd suggest for a pool has texture in it. That's the whole starting point, and it rules a few nice-looking finishes straight out.

The finishes that actually work

Exposed aggregate

The most common choice around pools and for good reason. Washing back the surface exposes the stone, which gives you natural grip that doesn't wear off the way a coating can. It also hides marks well, which matters on a surface that gets wet feet and sunscreen on it all summer.

Pick the stone with the heat in mind. A lighter aggregate stays noticeably cooler underfoot than a dark one, and around a pool that's not a small thing.

Spray pave, if you want the smoother look

Spray pave is what we point most people to when they want something smoother than exposed aggregate. It's a textured overlay laid over the concrete, so you get a tidier, more finished surface that still has grip when it's wet.

On a new pool surround that's two visits. We pour and finish the concrete, then come back a minimum of three weeks later, once it has cured properly, and lay the spray pave over the top. That wait isn't padding. Lay an overlay on green concrete and you're asking it to bond to a surface that's still moving.

It works just as well on an existing slab. If the concrete around your pool is structurally sound but tired, spray pave saves you demolishing and repouring, and it's often the sensible answer on an older pool where the slab itself is fine. The catch is what's underneath: if the existing slab has moved or is badly cracked, resurfacing it just gives you a nicer looking version of the same problem.

Honing, and why we don't do it on the top

Grinding and honing the top surface takes specialised machinery and training, and it isn't something we take on. When it is done it typically adds another $100 to $200 a square metre on top of the concrete itself, so once people see that number next to the pour, most of them don't go ahead with it.

Honing the edge is a different story and we can do that. If it's the smoother look you're after across the whole surround, spray pave gets you there for a lot less money.

Heat is a real constraint here

Gippsland gets properly hot in January and February. Dark concrete in full sun becomes something nobody wants to stand on.

• Lighter colours and lighter aggregate run cooler
• Think about where the shade actually falls in the middle of the day, not in the evening when you're standing there looking at it
• If part of the surround gets full afternoon sun, it's worth treating that section differently

Chlorine, salt and sealing

Pool water splashes out. Over years that leaves its mark on unsealed concrete, and salt water systems are harder on a surface than chlorine.

So pool surrounds are one of the places where sealing genuinely earns its keep. A sealer keeps the surface easier to clean and slows the staining. It's not permanent: expect to redo it periodically, and I'll tell you roughly how often for the finish you choose.

One thing to watch: some sealers make a surface slicker. Around a pool you want one that doesn't, and that's worth asking about specifically rather than assuming.

Falls and drainage get set before the pour

Water has to run away from the pool, not back into it, and not into a low corner where it sits. That's decided when we set the formwork, so it's a site visit conversation rather than something we adjust later.

If there's a low spot beside your existing pool that never dries out, that's a falls problem, and it's fixable, but not with a sealer.

Pool fencing changes the layout

Victoria has rules about pool barriers, including clearances around the fence line and what can sit near it. Those rules shape where the concrete can go and what can be built next to it.

I'm a concreter, not a building surveyor, so I won't give you the regulation as advice. What I will do is work to what your surveyor or pool builder has set out, and flag it at the site visit if what's planned looks like it'll run into the barrier requirements. Check the current Victorian pool safety rules through your council before finalising a layout.

Book in spring if you want it for summer

This is the practical bit. Pool surround work stacks up through spring, because everyone wants it done before the pool gets used. Concrete also needs its curing time, and you don't want that running into the first hot weekend.

If you're thinking about it for this summer, now is the time to get it looked at rather than November.

Book a proper site visit and we'll go through the finishes standing at the pool, where you can actually see what we're talking about. Or call me.
