Orlando5007 Posted April 13, 2020 Share Posted April 13, 2020 Hi all hope your well! I have to tile roughly 28sqm over a screeded floor which has water underfloor heating. The tiles are porcelain laminate wood effect tiles so thin and quite long. I want to keep the gaps to a minimum but have been told 3mm is the lowest I can go, is this correct?

Temp Posted April 13, 2020 Share Posted April 13, 2020 I've heard the same. Apparently the grout can crack and come out if the gap is too small. Link to comment Share on other sites More sharing options...
Mr Punter Posted April 13, 2020 Share Posted April 13, 2020 Yes and according to my tilers the tiles need to be really flat. Try pairing them back-to-back and front-to-front to test this. If they are a bit out they will be better if you reduce to, say 1/4 bond stagger. I have heard good reports of tile levelling systems which you may want to look at.

nod Posted April 13, 2020 Share Posted April 13, 2020 You can drop down to 2 mil 4 is better The Turkish and Chinese slats tend to have a camber So using a levelling system won’t help If you pay a bit more for laser cut Italian or even Spanish you will find these to be very flat Regardless of what you use you will need to back butter each tile with the smooth edge of your float Link to comment Share on other sites More sharing options...
