all the best Doug, my knees play me up, its not the being down, its the getting up that's hard, mine comes from years of tiling with wet screed and never wearing pads, in those days they dug into the back of the knee and were a real pain, i still hardly wear them, i do use a soft floor /garden mat to knell on but having to keep moving it is a headache. i have tried trousers with built in knee pads but as i'm short and on the cuddle size the pads are good for the shins only. I have cut down on my work load to save them a bit, . i remember a few years ago going to the doc with a left knee that i could hardly walk with without a stick , the doc said ' i have never seen such an old knee on a young man' i replied the right one is just as old why is that one ok,
anyway all the best for 2014
To all new tilers i echo Doug's warning '' wear the pads''
