Does anyone have any advice how to lay ceramic tiles onto a newly laid mineral felt ( concrete sub-base ) balcony? Many thanks, Keith

Hi Keith and welcome.. Sorry but not possible to tile onto that.

put a 50mm sand and cement screed over it

As above with fibres mixed in.

put a 50mm sand and cement screed over it

That has worked for me in the past

as above mate, worked for me too

is there a room under the balcony may need water proofing

 

[The Legend; Phil Hobson RIP]

Good point Jay, tanking first, membrane or paint on. Would help if there is a room below

Would tanking still be necessary if the felt is under the screed?

 

[jay]

I would for the simple reason
is it waterproof now

would help the screed if it was applied on top of screed .That way screed cant get waterlogged . The extra weight and the chance of freezing and possibly causing screed debonding

just a thought
