As per my related thread I will be tiling an outdoor area, although outdoors it has a roof and 3 sides. The open side does get rain sometimes blown in onto it, also when being in the garden would have wet feet so it needs to be slip proof or lets say not overly slippery. I used to paint it with a gloss floor paint which was not a non slip surface so we are used to being careful on it if its wet. The area is concrete and 2.8m x2.8m. I am looking for a grey tile and one that would fit in my 500mm cutter, I have found these Dotti Light Grey Matt Tile 300x300mm - Floor Tiles - CTD Tiles - https://www.ctdtiles.co.uk/p-4699-arkitect-dotti-light-grey-matt-surface-tile-300x300mm.aspx what do people think. Here is a picture of the area. Its the grey area ending with the slope, the yellow line marks the coverage of the roof line above.
