I've just installed a stone resin shower tray, as per instructions, on
a bed of 5:1 mortar. I'm sure the volumes were correct: I used 10
flower-pots full of sand and two of cement. I also put a bit of PVA in
as a plasticiser (again, as per instructions).
Now, after about 32 hours, I'm a bit scared that the bl**
*y stuff is
When I put the tray down there was a little mortar that oozed out of
the gap. I scraped this off and left it on a scrap of wood to see what
it was like when it had dried. Initially it was a browny colour, and
now it has gone grey so I thought it must be set. Unfortunately, with
a bit of effort, I was able to crush it between finger and thumb!
So, what do we reckon? Do you think it will be OK since the load is
spread across the whole area? What might be a suitable test to see if
will be OK in the long run?
I was thinking that if I stand on the tray and jump about a little
bit, and I see no crumbling at the edges, then it might be OK.
Any advice would be greatly appreciated. As you can probably tell I'm
panicing a little: I need to get on ASAP because this is the only
shower in the flat (and there's no bath).
