How to Make Wet Tiles Less Slippery Without Replacing Them

Short answer: you can make most wet tiles safer without ripping them up. A clear non-slip coating adds grip in one coat, keeps the look of the floor, and costs far less than new tiles. Here is how it works and how to choose one.
Why tiles get slippery
Glazed and polished tiles are smooth, so a thin film of water acts like a lubricant. It is worst where people walk in wet or barefoot: showers, patios, pool surrounds and the step outside the back door. For someone using a walker, a stick or a wheelchair, that one wet strip is often the biggest risk in the house.
What the P ratings mean
In Australia, floor grip is tested to AS 4586 and given a P rating from P0 to P5. The higher the number, the more grip in wet conditions. For outdoor areas that get wet, P4 or P5 is the level to look for. Indoors, bathrooms usually need at least P3.
Your three options
| Option | Good for | Trade-off |
|---|---|---|
| Clear non-slip coating | Keeping your tiles, quick fix, renters with the owner’s OK | Needs a clean dry floor and curing time |
| Acid etching | Some natural stone and unglazed tiles | Can dull the surface and can’t be undone |
| New non-slip tiles | Full renovations | Highest cost, days of work and mess |
How a clear coating is applied
- Clean the floor and let it dry completely.
- Mix the coating and roll on one even coat.
- Let it cure before you walk on it, then clean it with a mild cleaner.
Most home areas take an afternoon. We supply Stellmann Non-Slip Clear PRO P4, a 15 m² kit tested by CSIRO to P4 (the manufacturer’s test), and we can apply it in Victoria as part of a bigger job.
Pair it with the right ramp
If the slippery spot is also at a step or door sill, fix both at once. A rubber threshold ramp takes away the lip, and a non-slip coating on the tiles around it gives grip where you step off. Use our ramp calculator to work out the ramp size.
Common questions
Will a non-slip coating change how my tiles look?
A good clear coating dries invisible on most tiles and pavers. Test a small corner first if you are unsure.
Can I use it in the shower?
Yes, clear coatings are made for wet areas, including showers and bathroom floors.
How long does it last?
It depends on foot traffic and cleaning. Stellmann gives a 5-year adhesion warranty on its PRO coating, under its own terms.
