    Hi,

    This may sound a bit daft, we have just had a 53 sqm concrete pad made. We are looking at putting porcelain paving on top.

    Just a thought, would it be possible to use external glue on the paving slabs and stick this to the pad to make it an easier job? And then fill the gaps between tiles using grout?

    We are novice DIYers and it would make the job a lot easier and cheaper but if it would cause problems I would rather do the normal using mortar

    Please let me know your thoughts

    Thank you

    You should really follow the installation instructions for the tiles you are selecting. A powdered adhesive is most likely. Using leveling clips will make life a lot easier and afterwards you can use an appropriate grout as you suggest. You will need to prime the underside of the tiles to make the adhesive stick.

    It will be worth taking some time setting out accurately to minimise any fiddly cutting as porcelain tiles aren't the easiest to cut and mistakes are expensive. It's often best to start your setting out from a mid point - that can be either a tile or a joint, it depends what works out best.

    Good luck.

    As above - a powdered, external tile adhesive that’s suitable for porcelain tiles is your ‘glue’. Notched float to give a full adhesive bed for tiles

    SBR Slurry mix painted onto backs of every tile before laying

    External powdered grout to finish

    Basically, as you’ve had a concrete slab formed, this is now like tiling any wall or floor - same method

    So yes, you are essentially ‘glueing’ down the tiles - but using a suitable tile adhesive

    Cheap and a good job doesn’t often go hand in hand :eek:

    You’ve paid a fair few quid for the slab, more money for the tiles, don’t jeopardise the tiling aspect by skimping and using cheap materials - these tiles are going to be walked on and subjected to the weather come rain or shine and everything else in-between

    You would use mortar as the adhesive if laying on a wet mortar bed when you pour the slab and lay tiles all in one go

    Are you carrying out this work yourself or employing a trades peep ?

    Thanks for the reply @Diydave, looking at doing it ourselves

    How level is the slab? Judging by the number of queries we get on here the art of accurate slab laying is lost.

    53 sqm is a heck of a big job for a first try,

    The slab is pretty much perfectly level @stevie22, yes haha going to get a few people to help with it who are quite handy

    That's a shame. You need a fall for rainwater run off. That should also be in the installation instructions. If not, I would allow a fall of 1 in 80 - some people will advise slightly steeper, maybe 1 in 60.

    You might mean perfectly flat of course - they're often confused. It could be perfectly flat but so sloped that you can only have half a bowl of soup on the patio table...
