Sandstone Flooring: Everything You Need to Know

Sandstone Flooring: Everything You Need to Know

Sandstone flooring brings a unique combination of natural warmth, durability and timeless beauty to any space. Whether you are considering sandstone slabs for an open-plan living area, tiles for a kitchen floor or pavers for an outdoor entertaining space, this guide covers the full range of sandstone flooring options, costs, sealing requirements and long-term maintenance.

Why Choose Sandstone Flooring?

Natural sandstone has been used as a flooring material in Australia for over 200 years, and its popularity continues to grow. Here is why so many Sydney homeowners and architects specify sandstone for their floors:

• Natural warmth: Sandstone has a naturally warm tone and feel underfoot that creates inviting, comfortable spaces — a quality that porcelain and concrete tiles simply cannot match.
• Unique character: Every sandstone floor is one of a kind. The natural grain patterns, colour variations and mineral inclusions mean no two tiles or slabs are identical.
• Thermal mass: Sandstone absorbs and slowly releases heat, helping to regulate indoor temperatures. It pairs excellently with underfloor heating systems.
• Durability: Properly installed and sealed sandstone floors can last a lifetime. Many of Sydney's heritage buildings still feature their original sandstone floors after well over a century of use.
• Sustainability: As a natural, locally quarried material, sandstone has a lower embodied energy than manufactured flooring products shipped from overseas.

Sandstone Flooring Options

Stone Front offers several products suitable for flooring applications, each with distinct characteristics and price points.

Indoor Sandstone Tiles

Indoor sandstone tiles are the most popular choice for interior flooring. Precision-cut to standard dimensions and available in honed, polished and brushed finishes, they deliver a refined, elegant floor surface. Priced from $130 per square metre, indoor tiles are available in sizes from 300x300mm to 600x600mm. The honed finish is most commonly specified for residential flooring, as it provides a smooth, matte surface that is both attractive and practical.

Outdoor Sandstone Tiles

For covered outdoor areas, verandahs and alfresco spaces, outdoor sandstone tiles are the ideal flooring choice. Starting from $110 per square metre, these tiles feature slip-resistant finishes suited to areas exposed to weather. The natural split and sandblasted finishes provide the best grip for wet-area applications.

Sawn All Round Pavers

Sawn all round pavers serve as an excellent flooring option for both indoor and outdoor applications. At $120 per square metre, they are cut to your specified dimensions, allowing you to achieve a custom floor layout. Their diamond-sawn finish on all sides provides clean lines and a formal, contemporary appearance.

Sawn Flagging

For a more relaxed, informal floor — particularly in outdoor courtyards and garden rooms — sawn flagging at $85 per square metre delivers a charming, organic look with its irregular shapes and sawn edges. This is a popular choice for heritage-style properties and rustic outdoor spaces.

Sandstone Flooring Costs

The cost of a sandstone floor depends on the product chosen, the area to be covered and the installation method. Here is a summary of material costs:

• Sawn modular paving: From $65/m² — the most economical option for large floor areas
• Sawn flagging: From $85/m² — great value with a natural, irregular character
• Outdoor tiles: From $110/m² — precision-cut with slip-resistant finishes
• Sawn all round pavers: From $120/m² — formal, custom-cut flooring
• Indoor tiles: From $130/m² — refined finishes for interior spaces

Installation costs vary but typically range from $40-$80 per square metre for professional laying, depending on the substrate condition, tile size and installation method. For a complete cost breakdown, see our sandstone paver pricing guide.

Sealing Sandstone Floors

Sealing is the single most important step in protecting your sandstone floor. A quality sealer prevents staining, reduces moisture absorption and makes ongoing cleaning far easier.

Types of Sealers

• Impregnating (penetrating) sealers: These soak into the stone and protect from within, leaving the natural appearance and texture unchanged. This is the most commonly recommended sealer type for sandstone floors and the one we generally advise.
• Topical sealers: These sit on the stone surface and can add a sheen or gloss. While they provide a surface barrier, they can wear unevenly in high-traffic areas and may require more frequent reapplication.
• Enhancing sealers: A variation of impregnating sealers that deepen the stone's natural colour. These are popular for bringing out the warm golden tones of Sydney sandstone.

Sealing Process

For new installations, wait at least four to six weeks after laying for the stone and adhesive to fully dry before sealing. Clean the floor thoroughly and allow it to dry completely. Apply the sealer in thin, even coats following the manufacturer's instructions. Most impregnating sealers require two coats, with drying time between each. Reseal every two to three years for indoor floors, or annually for high-traffic outdoor areas.

Maintaining Your Sandstone Floor

Sandstone is a surprisingly low-maintenance flooring material when properly sealed. Follow these simple practices to keep your floor looking its best:

• Daily care: Sweep or vacuum regularly to remove grit and debris that could scratch the surface.
• Weekly mopping: Use a damp mop with a pH-neutral stone cleaner. Avoid acidic or alkaline cleaning products, bleach and abrasive cleaners.
• Spill management: Blot spills promptly — especially wine, coffee, oil and acidic liquids. A well-sealed floor will resist most stains if spills are addressed quickly.
• Periodic deep clean: Once or twice a year, use a dedicated stone deep cleaner to remove any built-up grime.
