OK so I have a 'hidden agenda' - BUT TactTiles are just great for shed and greenhouse floors. Easy and fast to lay they are non-toxic UV stable and readily re-fitted if your shed expands / re-shapes.
TactTiles make superb home kiddies play areas (lots of colours) and even better home Sports Arenas (bespoke for your garden). www.tacttiles.com and get the low-down from Andrew.
