No More Ply for laying 600x300 porcelain - TilersForums.com

[On one]

One 12mm layer will be cheaper and quicker than two 6mm layers.........if it was even needed in this case,which seems doubtful!
Looks like overkill and added difference in height to the floor

How much is NMP + glue?

Around £9 a sheet and £7 per tube of pu glue. Their self tappers also £7 for 200

Cheers for the help lads. The reason I wanted to double up the 6mm is that it is much more dense than the 12 mm and I thought it would give a stronger floor.

Another option would be to put 12mm ply down and tank it. Does any one still use ply.

No tiling on ply is a thing of the past.. if you are happy with the additional height, just put one 12mm NMP down and you'll be sorted, but as others have said, if you dont need the height, one 6mm NMP should suffice

If you really want to strengthen the floor go with permat. It gives a 10 year deflection warranty

I've never seen deflection measured in years....
