600 x 300 porcelain floor tiles that bend

[grumpygrouter]

Maybe a good way to check for this problem is have 2 tiles face to face and see if they rock. If they are flat they won't move.

got 1000x300 to start next week, luckily they're ceramic so won't have been fired to stoneware temps, but still hope they're not brickbond!

This IMO is a production fault and lack of quality assurance on the manufactures part, unfortunately they will not accept liability once the tiles are fixed. (States it on every box) That's ok play by there rules next time and fault the tiles before you fix them then watch the tile shop run for cover, let them earn there coin, I get sick to death of seeing this problem week in week out and the only way to get around it is to get the tile shop to keep sending out tiles UNTIL THEY GET IT RIGHT!!!!

I recently done 200m2 of 600x300 porcelain and before I even started I faulted 125m2 with the same issues needless to say the tile shop was not happy with me, but as I kept saying "Stop selling the public S*** that you buy for $5 bucks a meter and then charge the client $45m2 If that ain't enough FAT on your C*** product for me to whinged a bit about a diserning client that commands perfection You'll keep replacing them until I say STOP!!"

The trouble is the tolerance that is allowed is i think 5% but i must say the cheaper the tile the worse it is try to stick to italian porc chinese porc is rubbish :mad2:

I always thought they warped during firing?

Thats debatable doug......some do, some don't...but incorrect stacking of them doesn't help..

Exactly Dave, The trouble lies where in China and India they use smaller kilns and have larger production runs, meaning the tiles need to be stacked at higher temps to continue production, Usually the tiles need to be cooled slowly very slowly the slower the less variation in size and deflection, Also the Italians and the spanish manufactures will commonly have over a dozen caliber sizings, by this I mean for instance a production run of a particular style of tile say 10 000m2 once cooled will be sorted into different caliber sizes usually a-n this will be on the box, 'a' usually the smallest in the series and 'n' being the largest. This takes time and costs money, money that goes into the eventual cost of the tile. Other manufactures would be lucky to sort 2-3 caliber sizes and stack them hot, hence the facial distortion that has become so common. 15 years ago these problems where rare.

I think this is a problem that alot of newcomers encounter. one of my first jobs after my tiling course was 600 x 300 porcelain brick bond in a shower cubicle. Tiled it with a 2mm grout line thinking it would look Gucci and just couldn`t avoid lipping! took me for ever to get it right - the spot lights above beaming down showed awful shadows. I never would of known why if it was not for the forum.
