Outside patio tiled 600x600 porcelain

Why can't you fix direct into a sand and cement bed? I would still create a sub-base with metal for movement but I would then fix directly into s&c. Done it lots of times outdoors. I don't see the difference to laying flagstones.

I feel more comfortable with a trowel and thin bed installation tbh.

Right......need to get the quote sorted by Friday

I will do it as posted......will use gully drains instead of paving blocks as Ttt1601 sugested,
will try to reconnect to existing drainage system instead of soak away(unless not possible)
What fall would you sugest on 3.4m run???

Is Ultracolour (mapei) ok to grout it or shall I go for a different product(needs to be black)

You should aim for a minimum of 25mm per metre fall so around 85 mm over 3.4m no ,I got that wrong that is 1:40 you can be at 1:60-1:80 on a patio so anything from 40mm to 60 mm fall would be fine

Got quote accepted...hurray.
Client decided to have it raisedone so it will allow to drain water to the gullys and hopefully connect to existing drainage system.

I will install aco drain against house wall as getting close to damp coarse level and one at the end of the patio.....
One more issue (hope not)is screed ok to go outside (ready mixed sand&cement fibre reinforced)as would prefer than concrete.....it's perfect flat finish what I'm after
And is Ultra colour by Mapei ok to be used externally.

Thanks guys for all reply and sugestions

I have room to play now with fall but 1:80 would be minimum.

Well....customer wants to go up to patio door....so will be over dcl.....Acu gully will go against the wall

I know I could get like clear membrane to protect walls but it's not permanent solution it's paint like product so I guess every now and then needs to be applied...

Not looking forward to it whatsoever....or maybe I'm getting to anal about it
