IKEA deck tiles

I have these. They look lovely when down and are super easy to lay and put down as they just click together.  I have laid mine on a concrete slab.  They are not slippery when wet and do not discolour over time unlike the wooden ikea ones which I had previously as they needed staining and re varnishing every year.  I did not bother buying the edging strips as I have gravel round my patio areas so it was not necessary.  Hope this helps
