What type of tile is not slippery?

The best type of tiles that aren't slippery is exterior grade R11 or higher-rated porcelain tiles. These flat outdoor tiles have a more textured grip surface which makes them less slippery. The textured surface of the tile provides traction and reduces the risk of slipping.

Our huge range of non-slip outdoor tiles includes a variety of textures, from smooth to rough, so you can find the perfect tile for your project. 


Grip Ratings Explained

When selecting outdoor tiles, it's important to consider the grip rating. Grip ratings indicate the slip risk of the tile. Based on an international slip resistance test, the higher the rating on the ‘R’ scale, the better the slip resistance. 

Outdoor tiles are in the range of R11 to R13.


Rating Guide:

  • - R11: (Standard/ most common slip rating). Suitable for interior and exterior use.
  • - R12: High Slip Resistance. Suitable for outdoor use, such as pools, patios, and balconies. It can be used in light commercial areas.
  • - R13: The highest level of slip resistance. Ideal for ramps, stairs, swimming pool surrounds and heavily trafficked external areas.


What are the best slip-resistant floor tiles for indoors? 

Porcelain tiles with a grip rating of R10 are recommended for indoor areas that are exposed to moisture and water, like bathrooms, kitchens and even entryways that receive a lot of foot traffic. Easy to clean and maintain, non-slip flooring tiles have a matt finish and are able to withstand frequent splashes of water. 

Our slip-resistant floor tiles come in a range of sizes and shapes ranging from XL format tilessmall and standard sized tiles all the way to unique shapes like herringbone, chevron, penny rounds, and hexagon, to name a few.

What are the best tiles to use outdoors? 

The best tile to use outdoors is one that is non-slip and has a grip rating of R11 and higher. This ensures that your outdoor tiles provide a safe surface for walking on. When selecting an outdoor tile, it’s important to take into consideration, 

  • - The type of area you’re tiling 
  • - How much foot traffic the area will receive 

For areas that will receive heavy foot traffic, it’s best to select a tile with a higher grip rating. 

R11 is the most common grip rating we see among tiles for high foot traffic.

Let's take a deeper dive into non-slip exterior tiles, which have a high grip rating of R11 or higher. 


How do I make existing outdoor tiles not slippery? 

If you’re looking to make existing outdoor tiles not slippery, then there are a few options. One option is to apply a non-slip coating or treatment to the tile surface. These products will create a textured surface that provides extra grip and helps prevent slips and falls. 

Another option is to use an anti-slip mat or adhesive strips on the tile surface. This will help increase traction and reduce the risk of slipping.


Installing Outdoor Tiles


Can you put outdoor tile over concrete?

When installing outdoor tiles, you must ensure that you have the correct base for your tile.

The best base for outdoor tile is a concrete slab in combination with an appropriate adhesive for the type of tiles you are using.

Ensure that the surface is clean and free from cracks or defects before laying the tile.


Do you need to waterproof under outdoor tiles?

You don’t need to waterproof outdoor tiles laid on ground level. Waterproofing under outdoor tile is only required if the tiles are laid on first-floor balconies- and this is only if it uses a 20mm paver on the decking jack system.


Do outdoor tiles need grout?

Yes, you have to use grout when installing outdoor tiles with 10mm tiles. If you’re using 20mm tiles you don’t need to use grout.

Grouting the 10mm tiles will prevent water from seeping into the structure and the surrounding areas of your outdoor space.

Be sure to choose a grout colour that complements your outdoor tile choice.

Deck Jacks - What Are They & Why Do I Need Them?

If your outdoor tiles are 20mm or thicker tiles and installed on a deck, you need to consider using deck jacks to raise them off the ground. 

This will ensure that the tiles are even and level as well as provide a gap between the tile and the surface for drainage. 

Deck jacks will also help to provide additional grip and reduce the risk of slips and falls. 

Deck jacks are only used for 20mm or thicker tiles, and not for 10mm tiles on jacks. Deck jacks are great if you don’t want to pour concrete. Check out our complete guide to outdoor deck tile systems in NZ for more detailed info.


Are non-slip outdoor tiles suitable for steps?

Yes, absolutely! Non-slip outdoor tiles are ideal for steps as they provide excellent grip, even in wet conditions.

When selecting tiles for steps, look for a tile with a higher grip rating, like R11 or R12. This will ensure that your steps remain safe and slip-free all year round.
