Taking up and re-laying a stone resin tray

[Carpenters daughter]

so long as the floor was flat and the tray didn't rock a thick bed of silicone is all that's needed - which is what I used and all is well.

Funnily enough thats exactly what hubby used on the old tray 16 years ago. Worked a treat. He only agreed to use the sand and cement cos that was what Simpson's said to use. I need to stop being so hard on the poor guy don't I?
