Picture this: it’s a perfect summer afternoon. The barbeque is sizzling, friends are laughing, and the kids are making a dash from the back door to the pool. In this perfect picture, the last thing you want is a frantic hop-scotch across paving stones that feel as hot as the grill itself.
This brings us to one of the most common questions we hear at BuildMart Australia from homeowners designing their dream outdoor space: “I love the look of bluestone, but do bluestone pavers get hot?”
It’s a crucial question. You’re not just investing in a look; you’re investing in a lifestyle. Let’s dive into a clear answer, explore the science, and give you practical solutions to create a bluestone space that is both stunning and comfortable, even under the harsh Australian sun.
The Direct Answer: Yes, Bluestone Can Get Hot
Let’s not beat around the bush: yes, bluestone pavers can get quite hot in direct, sustained sunlight. Like any dark, dense natural stone, they are very good at absorbing and holding onto thermal energy from the sun. Think of it like a dark-coloured car parked in the sun compared to a white one, the dark surface will always feel hotter to the touch.
But here’s the key: this is a manageable characteristic, not a deal-breaker. Understanding why it happens is the first step to designing a comfortable and beautiful outdoor area.
Why Some Pavers Get Hotter Than Others
Not all pavers are created equal when it comes to heat. The temperature of a paver’s surface comes down to two main scientific principles: colour and density.
The Role of Colour (Albedo Effect)
This is the most intuitive factor. Lighter-coloured surfaces reflect more sunlight and solar energy, while darker surfaces absorb it. This phenomenon is known as the Albedo Effect. A paver with a high albedo (light colour) will stay cooler than a paver with a low albedo (dark colour). Bluestone, with its signature deep grey and charcoal tones, naturally falls into the low albedo, high-absorption category.
The Impact of Density (Thermal Mass)
Thermal mass refers to a material’s ability to absorb, store, and release heat. Bluestone is a very dense and solid natural stone. This high density means it has a high thermal mass, it acts like a heat battery. It takes a while to heat up, but once it’s hot, it holds that heat for a long time, even after the sun has started to set.
Heat Comparison: Bluestone vs. Other Popular Pavers
So, how does bluestone stack up against other options for heat resistance in Australia? Here’s a quick comparison of popular choices available from BuildMart.
Bluestone: High heat absorption. It gets hot underfoot in direct sun but offers unparalleled durability, a premium aesthetic, and timeless appeal.
Travertine: Low heat absorption. Often regarded as one of the coolest natural stone options, travertine’s light colours and natural porosity help it dissipate heat quickly. This makes it a top choice for pool surrounds.
Light-Coloured Concrete Pavers: Good heat reflection. A versatile and often budget-friendly option, light grey or off-white concrete pavers will stay significantly cooler than dark stone.
Sandstone: Varies by colour. Lighter sandstone tones, like creams and beiges, perform well in the sun and stay relatively cool. Darker sandstone varieties will absorb more heat.
5 Practical Ways to Keep Your Bluestone Pavers Cool
You’ve got your heart set on bluestone, and we don’t blame you. The good news is you can absolutely have it without creating a hot spot. It’s all about smart design and strategic choices.
1. Choose Lighter Tones & Finishes
Not all bluestone is a uniform deep charcoal. Variations exist, such as European Bluestone, which can offer slightly lighter, more varied grey tones. Even a subtle shift to a lighter shade can make a noticeable difference in surface temperature.
2. Design with Strategic Shade
This is the most effective method. By preventing direct sunlight from hitting the pavers during the hottest parts of the day, you solve the problem at its source. Consider building a pergola, installing a shade sail or cantilever umbrella, or planting deciduous trees that provide summer shade and let in winter sun.
3. Use a High-Quality Paver Sealant
While a sealant’s primary job is to protect against stains and moisture, some high-quality sealants can add a slight sheen that may help reflect a tiny fraction more solar radiation. More importantly, it keeps your pavers looking their best.
4. The Simple Power of Water
If you have a pool, the problem often solves itself with splashing. For patio areas, a quick hose down before guests arrive can dramatically cool the surface for hours, releasing the stored heat through evaporation.
5. Break Up the Surface
You don’t need a wall-to-wall sea of stone. Clever design can reduce the total exposed surface area. Place a large, light-coloured outdoor rug under your seating area, or integrate strips of grass or garden beds between sections of paving.
The Verdict: Is Bluestone a Good Choice for Your Aussie Home?
Absolutely. While bluestone’s heat absorption is a real consideration, its benefits are immense. It is incredibly dense and hard-wearing, capable of withstanding heavy traffic and harsh weather for decades. Its sophisticated, consistent colour provides a stunning backdrop for any style of home, from modern minimalist to classic heritage.
By understanding its properties and incorporating smart design choices, you can enjoy all the durability and beauty of bluestone without compromising on comfort.

Frequently Asked Questions (FAQ)
What is the coolest paver material for bare feet?
Light-coloured travertine is generally considered the coolest natural stone paver for bare feet due to its high reflectivity and porosity, making it a favourite for pool decks.
Will sealing my bluestone pavers make them cooler?
Sealing pavers won’t dramatically reduce their temperature. Its main purpose is protection. However, a quality sealant is a crucial step in maintaining the look and longevity of your investment.
Can I use bluestone for pool coping in a sunny area?
Yes, you can, and it looks stunning. However, it will get hot. If your pool area is in full, all-day sun and will be used frequently by children, you may want to consider a lighter stone like travertine for the coping or ensure you have adequate shading.
