Are Sandstone Tiles Slip Resistant for Outdoor Areas?

Are sandstone tiles slip resistant for outdoor areas?

Sandstone tiles can offer good grip in paved areas, thanks to the texture and character of natural stone. However, being made from sandstone does not automatically make every tile equally slip-resistant. The finish, natural grain and conditions around the installation can all influence how secure the surface feels when you walk on it.

What gives natural stone flooring a good grip?

Sandstone is often chosen for the house's exterior spaces because its surface has a naturally earthy, textured feel. That gives it a different underfoot character from smooth stones that have been heavily polished.

But there is an important distinction between the stone itself and the finished tile. Sandstone can be cut, honed, or finished in various ways, and these treatments can affect the grip of the sandstone tiles.

How does water affect sandstone tiles in paved zones?

Water can change the safety conditions of the floor. Rain, splashing, cleaning, and everyday moisture can leave an outdoor area wet, so a tile needs to be suitable for the conditions it will regularly encounter.

The amount of water an outdoor space receives can also vary. An open garden path may become wet after rainfall, while the pool area or outdoor showers can experience frequent splashing. Covered spaces may have less exposure, but they can still become wet during cleaning or heavy weather.

Wet Conditions Can Increase Slip Risk

Walking on wet tiles is different from walking on them when they are completely dry. Water can reduce the grip between your feet and the floor, especially when it remains on the surface instead of draining away.

Barefoot use also deserves attention in places such as pool surrounds and open-air showers. These areas are regularly exposed to water, so the chosen tiles should be suited to that type of use.

Good Drainage Helps

Getting non-slip sandstone tiles is not enough. Drainage also plays a role in keeping outdoor areas safer after rain, cleaning or splashing. When water can flow away efficiently, it is less likely to collect and remain across the walking area.

Poor drainage can leave sections of paving continually damp or covered in standing water. That can create conditions where slipping becomes more likely.

Are sandstone tiles suitable around pools?

Sandstone tiles can be suitable around pools, but the setting calls for careful attention because people regularly walk across the area with wet, bare feet.

Pool surrounds experience frequent splashing, water carried out by swimmers and moisture around the pool edge. These conditions can make slipping a greater concern than in outdoor areas that stay mostly dry.

This is where pool area safety becomes a key consideration. The tiles should provide a suitable grip for barefoot use and remain appropriate for regular exposure to water.

The area around a pool also includes steps, edges and coping, where people may change direction, enter or leave the water, or move between different levels. These areas should be considered as part of the overall pool design.

Before choosing sandstone tiles for a pool surround, check the product's intended use and any available slip-resistance information. That gives you a better indication of whether the product suits the conditions it will face.

What about sandstone tiles for other wet areas?

Pools are not the only places where outdoor stone may regularly become wet. The same selection principles can apply to other areas where water is part of normal use.

Outdoor showers are an obvious example. Water can land directly on the paving, so the surface should withstand regular exposure to water and foot traffic.

Alfresco areas can present a different situation. A covered area may stay dry for long periods, but wind-driven rain, spills, cleaning and water carried in from the garden can still make sections of the floor wet.

Garden paths and steps can also remain damp after rainfall, especially where shade limits evaporation. Leaf litter, moss and other organic material can create additional slip hazards.

This is why choosing sandstone tiles should start with the conditions they will experience. A product suitable for a sheltered patio should not automatically be assumed to suit a constantly wet location.

Can sealing and cleaning affect sandstone?

The condition of a stone surface can change after installation. Sealing and cleaning are therefore part of the long-term picture, especially in outdoor spaces exposed to dirt, moisture and organic material.

What to Know About Sealing

Sealing is used on sandstone to help manage staining and maintain the surface. However, a sealer should not automatically be described as making a surface more slip resistant. The effect can vary depending on the product, application, and resulting surface.

Before sealing sandstone in a wet area, check the stone supplier's recommendations and the sealer manufacturer's instructions. The aim should be to choose a compatible treatment without creating an unwanted change to the walking surface.

Keeping the Surface Clean

Maintenance can influence how a surface performs over time. Dirt, residue, organic growth and unsuitable cleaning products can alter the surface people walk on.

For outdoor sandstone, routine care can include removing leaves and other debris, washing away surface dirt, and addressing organic growth before it becomes established. Follow the stone and cleaning-product manufacturer's instructions, as aggressive products or unsuitable methods can damage natural stone.

The goal is not to make the surface artificially rough. It is to keep the installed surface in the condition intended by the manufacturer and installer.

How should you choose sandstone tiles?

The best starting point is the area itself. Once you know how the surface will be used and how much water it is likely to encounter, you can assess the tile against those conditions.

Match the Tile to the Area

Start with the environment.

A covered patio, garden walkway, pool surround and outdoor shower do not experience the same level of moisture or foot traffic. Pool surrounds also involve barefoot use, while garden paths may be exposed to rain, leaves and soil.

Make a list of the conditions the tile will face throughout the year:

• Regular rain or occasional exposure
• Standing water or good drainage
• Barefoot or shoe traffic
• Pool splashing or shower water
• Heavy or light foot traffic
• Direct sunlight and weather exposure

This gives you a clearer basis for discussing product suitability with your supplier.

Check the Finish and Test Information

Ask about the finish before deciding. Two natural stone products can have noticeably different surface characteristics, even though both are sold as sandstone.

For areas where slip resistance is a key consideration, ask if the product has been tested under the conditions relevant to its intended use. AS 4586 provides Australian test methods and classifications for new pedestrian surface materials, while the NCC uses classifications based on application and wet or dry conditions.

Don't assume that a product described as “non-slip” has the same performance as every other tile carrying that description. Product documentation gives you a stronger basis for comparison.

Consider Installation and Long-Term Care

A good tile still needs a suitable installation.

The paving layout should allow water to drain away from walking areas, with site levels and drainage planned. Edges, steps, and transitions also require careful installation because an uneven surface can create a trip hazard, even when the stone itself has good grip.

Long-term care then becomes part of preserving the surface. Keep the paving free of leaf litter and other buildup, follow the recommended cleaning methods, and use sealing products in line with the stone supplier's guidance.

The Australian approach to slip risk also recognises that surface selection is only one part of the picture. Design, drainage, maintenance and the conditions in which the surface is used all contribute to managing slips and falls.
