Tiling help

About to start tiling our kitchen which is a 35m2 rectangle (7.6 x 4.7M) and need a bit of advice about an expansion joint, do I need one?


The tiles I am using are 600x 600 x 10mm porcelain, evo-stik flexible adhesive and a Raimondi RLS leveling system which leaves a 1.5mm grout line. I plan to leave a 10/12mm gap around the edges which will be covered by skirting board. There is no underfloor heating and it is a concrete slab.



Any advice appreciated, the more I read online the more confused I get; I'm finding lots of conflicting opinions about the max size of an area of tiles without expansion.



Thanks.

You should be fine to tile away.If there is an expansion joint in the concrete floor you will need one in the tiling.To be honest unless you are a very capable diyer I wouldn't recommend taking on this, also mind your back when laying the tiles 600 square tiles are hard on the back.

Cheers Mick,


Found a BS standard since that any bay of tiles over 10M in any direction requires an expansion joint, reading about online its best to keep it to 8M so I should be fine. I have no expansions on the concrete slab and no visible cracks either.



I have done a few bathrooms and the like before, so I should be OK-too late now anyway

I'd say you're grand, chances are it's flexible adhesive anyway.Its looking good.What colour grout are you using?

I'm using evo-stik OPF flexible and grey grout.

I lifted the first tile and checked for coverage yesterday, all seemed god no ridges left.

I measured the side of the tile this morning after the first few dried, seems to be about 3mm of adhesive under the tiles, hope this is enough?

Using a 10mm notched trowel for the adhesive and back buttering enough to fill the gaps/ridges on the underside of the tiles.

You should be fine so,once there is no hollow sound when you tap around the tile.Grey grout I'd perfect as slot of places sell you ivory etc as it blends in better but it won't be long going very dark.
