Choosing the right tile isn't just about colour, size or style. One of the most important considerations, particularly for wet areas and outdoor spaces, is slip resistance.
If you've ever looked at tile specifications and seen terms like P4, P5 or R11, you're not alone in wondering what they actually mean.
At Myaree Ceramics, one of the most common questions we receive from builders, designers and homeowners is how to choose the right slip rating for a project. Understanding the difference between P and R ratings can help you make safer, more informed decisions when specifying tiles.

What Are Tile Slip Ratings?
Slip ratings are a way of measuring how resistant a tile surface is to slipping under particular conditions.
In Australia, two primary testing methods are commonly used:
P Ratings
P ratings are measured using a pendulum test on a wet, flat surface. The higher the P rating, the greater the slip resistance.
Common ratings include:
P1: Low slip resistance
P2-P3: Moderate slip resistance
P4: High slip resistance
P5: Very high slip resistance
The P rating system is often used when assessing residential and commercial applications where floors may become wet.
R Ratings
R ratings are measured differently. The test involves a person wearing safety boots walking on an inclined ramp coated with oil. As the surface angle increases, the slip resistance of the tile is evaluated.
Typical ratings include:
R9: Low slip resistance
R10: Moderate slip resistance
R11: Higher slip resistance
R12-R13: Very high slip resistance
R ratings are commonly used in commercial, industrial and outdoor environments where slip resistance requirements can be more demanding.
Why Higher Isn't Always Better
A common misconception is that selecting the highest possible slip rating is always the safest choice.
While slip resistance is important, a heavily textured surface designed to achieve a very high slip rating can be more difficult to clean and maintain. The texture that provides grip can also trap dirt, grime and other contaminants.
This is why it's important to choose a tile that meets the requirements of the space rather than automatically selecting the most slip-resistant option available.
The goal is to strike the right balance between safety, functionality, appearance and ongoing maintenance.
Don't Forget Maintenance
The performance of a non-slip tile doesn't end once installation is complete.
Textured surfaces often benefit from an industrial-strength post-installation clean to remove grout haze and construction residue. This helps maintain the tile's appearance and makes future cleaning easier.
Depending on the application and traffic levels, periodic deep cleaning may also be required to keep the tile performing as intended.

Recent Innovations in Slip Resistant Tile Technology
Tile manufacturing continues to evolve, and one of the most exciting developments is the introduction of "in/out" technology.
These innovative surfaces are designed to feel smoother and be easier to clean while providing increased slip resistance when wet. This allows designers and homeowners to achieve a seamless indoor-outdoor look without compromising on safety.
Advancements in manufacturing techniques have also improved the appearance of textured surfaces, meaning you no longer need to sacrifice aesthetics to achieve practical slip resistance.
The Importance of Correct Specification
Slip ratings should always be selected based on the intended application, not simply the desire for the highest number.
Factors such as whether the area is indoors or outdoors, residential or commercial, wet or dry, and the maintenance expectations of the end user all play an important role in determining the most suitable tile.
At Myaree Ceramics, we recommend consulting the latest Australian Standards and current CSIRO guidance when determining slip resistance requirements for specific projects. The most appropriate slip rating will vary depending on the space and its intended use.
