KER515 Kerastar Graphite Diamond anti-slip floor tile 20x20cm by Johnson Tiles.
A practical and hard-wearing porcelain tile with a rough matt texture and an R12 anti-slip rating which is frost-proof. The Kerastar Graphite Diamond imitates black speckled granite which is a volcanic rock comparable to basalt. The word “granite” comes from the Latin granum which refers to granite’s signature granular texture. It is suitable for exterior use.
Tiles classified as an anti-slip floor tile are assigned an ‘R’ value which runs along a scale from R9 (not tested but manufactured to a minimum standard) all the way through to R13 (the highest slip resistance). As the Kerastar Graphite Diamond has an R12 slip rating, it is regarded as safe for fitting in all areas, both wet and dry, including bathrooms, wetrooms and kitchens and even public toilets and swimming pools.
Frost-proof tiles are an important consideration for rooms where the temperature may drop below zero such as utility rooms and conservatories. Tiles with a frost-proof glaze have a water absorption rate of less than 0.5% meaning they are ideal for such conditions. Tiles which are not frost-proof may absorb water which would freeze at zero and below, causing the tile to crack.
