thanks peeps great ideas just had that last night said to wife Im off to general george to fimd a grey nylon man made with no rubber backing as this must be water/rot proof. only thing is I went to the shop asked the guy for a man made possibly outdoor carpet - he looked at me strangely. I looked around but nothing that would look similar a;lso they all had a thick white nylon felt - ish backing which I thought would just hold more water. anyone else tried ordinary carpet. I was hoping to ohnly replace the floor as I have all the other pieces which I have jetcwashed ready to stick bak on with the carpet adgesive from spray cans - is this Ok or should I replace all carpet using the old one as a template ????? decisions decisions ?????????????????
