Liquid Limestone vs Honed Concrete for Perth Pool Surrounds

Two finishes turn up in most pool surround quotes in Perth. Liquid limestone, the pale cream surface you see around pools all over the city, and honed concrete, poured then ground back and sealed. They feel different underfoot, they age differently, and one costs close to twice the other. Neither is the right answer for everyone.

The short answer

Pick liquid limestone if you want the coolest surface underfoot, a coastal or Hamptons look, and the lower price.

Pick honed concrete if you want a specified-looking floor that carries from the pool through the alfresco and into the house, and the budget can take close to double.

Side by side

	Liquid limestone	Honed concrete
Rate installed, GST inc	$85 to $115 per m2	$160 to $210 per m2
40 m2 surround	$3,400 to $4,600	$6,400 to $8,400
Heat underfoot	Coolest common finish, the pale colour reflects	Depends on the mix, pale is fine, charcoal is hot
Grip when wet	Good, better again lightly textured	Good with matte sealer and anti-slip additive, not gloss
Reseal	Every 2 to 5 years, pools at the shorter end	Every 2 to 5 years, pools at the shorter end
Repairs	Patches blend reasonably well	Hard to match grind and sheen
Suits	Coastal, Hamptons, white render, limestone walls	Architectural, concrete and steel, dark joinery
Can continue indoors	No	Yes

Heat underfoot

Colour does most of the work here, not the finish name. Light surfaces reflect the sun, dark ones absorb it.

Liquid limestone is crushed WA limestone with white cement, so it is pale by default. That is a big part of why it became a Perth staple around pools. In full January sun every surface warms up, but bare feet cope with cream limestone better than with dark pavers or plain grey concrete.

Honed can be pale too, with a white cement mix and a light grind. The catch is that most people choose honed for the moody grey or charcoal look, and a charcoal slab at 2pm in February will be hot. Want honed with barefoot kids? Specify a light base colour.

Shade outranks both. An unshaded slab of anything gets hot.

Grip when wet

Liquid limestone has a slightly open surface. It can be lapped smooth or left lightly textured, and around a pool the textured version is the one to ask for.

Honed is ground flat, so slip resistance comes almost entirely from the sealer. A matte hone with an anti-slip additive performs well around water. High gloss polish is an indoor finish, not a pool one.

If grip beats everything else, neither wins. Exposed aggregate has the most bite of any finish we pour, because the stone texture does the work rather than a sealer.

What each costs, on a real 40 m2 surround

Say 40 m2, a mid-size pool with a walkway on three sides. That sits in the standard rate band of 30 to 79 m2, so there is no size adjustment either way.

Liquid limestone: 40 x $85 = $3,400 at the low end, 40 x $115 = $4,600 at the high end. So $3,400 to $4,600.

Honed concrete: 40 x $160 = $6,400 at the low end, 40 x $210 = $8,400 at the high end. So $6,400 to $8,400.

Same slab, and honed costs about $3,000 to $3,800 more. Both include GST, installed.

Most surrounds replace something, so add removal. Taking out old pavers or concrete runs $35 to $60 per m2 and does not get the size adjustment, so 40 x $35 = $1,400 up to 40 x $60 = $2,400. That takes limestone to $4,800 to $7,000 and honed to $7,800 to $10,800.

How each ages

Both finishes need a sealer, and both need resealing every 2 to 5 years, at the short end around a pool, because chlorine, salt splash and sun are hard on sealer.

What differs is how each tells you it is due. On limestone, a tired sealer shows as marking: sunscreen, leaf tannin, a spilled drink that soaked in. Rinse chemical splashes off instead of letting them dry and you buy time. On honed, it shows as dull patches in the sheen, most obvious in low afternoon sun, so it announces itself earlier.

Fine surface crazing can appear in any cement product as it cures. SL72 mesh and control joints cut within a day or two are there to steer movement into the joints rather than across the middle of your surround.

Repairs

Neither one patches invisibly. Anyone who says otherwise is selling.

Limestone is the more forgiving. The speckled cream tone and light texture hide a repair reasonably well, and new work that starts out brighter settles closer over a season or two.

Honed is hard to patch. A repair means grinding, and matching the depth, stone exposure and sheen of a floor that cured years ago is difficult work with a visible result.

Either way: if a trench is likely for pool equipment, retic or a future extension, plan it before the pour. We raise that at the free site visit, and the full sequence is on our process page.

The look each suits

Liquid limestone reads coastal. White render, dark window frames, pale coping, limestone retaining, plant-heavy beds. No paver joints for weeds or ants, and coping can be formed straight in.

Honed reads architectural. It suits concrete, steel, spotted gum and black tile. Its strongest argument is continuity: if the floor inside is polished concrete, honed outside carries the same material through the sliding door. Limestone cannot do that.

Where exposed aggregate and plain concrete fit

Exposed aggregate sits between the two at $115 to $155 per m2, so 40 m2 lands at $4,600 to $6,200. Best grip, hides marks well, tough. The trade-offs are texture, which some find coarse underfoot, and heat with a dark blend.

Plain and coloured at $75 to $110 per m2 is the budget option. Plain grey glares in summer and a dark oxide gets hot, so pick the colour with the pool in mind.

How to decide

• Coolest underfoot for the money: liquid limestone, lightly textured.
• Best grip with wet feet: exposed aggregate, or textured limestone.
• Matching an interior polished floor: honed concrete, matte, anti-slip additive.
• Big surround, tight budget: limestone or plain, and spend the difference on shade.
