Patio tiles - Porcelain

[stevetyson]

My customer has bought B&Q porcelain patio tiles 600x600 can you give me some tips on how to lay 50 square metres.
The name is kalestone Pergermon Porcelain. I have prepared the base for a normal patio flag and the customer has come back with porcalain because they were in the sale 50% discount.
I need to know what is the best sub base to use,

waiting in anticipation

Cheers Steve

Sub it to a tiler no harm to you but a clients patio is no place to learn how to tile. A tiler should have it done in 2 days max so it would cost no more than £350-£400 plus adhesives and grout. Does the concrete have a suitable fall on it for water to dispell.

Sorry for the misleading question. I have now altered it. I can tile but I have done the base for a normal stone patio flag

As in an dtp1 subbase, if so you cant tile on that, a concrete base is probably your only option in this instance - how thick are they?

cheers DN for your promp reply, the tiles are 10mm thick.
The sub base is 150mm deep 40mm crush and run wackered down, someone has told me I can use a sand base screed bed, 1.3cm deep does this sound ok to you?
Cheers again

Im not so sure about the sand bed option, if i were doin it id lay a concrete base - in place of the compacted "crush and run" and lay tiles as you normally would on to adhesive etc etc - (if that can be doin in exterior applications?)

Normal spec would be 100mm compcted type 1 then min 75mm 30nm concrete. Best to throw some 6mm steel mesh into it aswell. I would use either cement or exterior adhesive and prep it with a deep groove trowel. Don't use any sand as it will weaken the bond. You cannot lay the tiles directly onto the stone and laying them like flags on mortar will be impossible to get right.
