Are my expectations too high?

Its been a while but just so you are all aware having spoken to the TTA it appears that technically a lip on a floor tile can be as thick as a pound coin 3mm.

Flatness and variation from plumb:
± 3mm under a 2m straightedge.

I was told if I used a 2m length of wood with a pound coin under each end, the floor tolerance can technically drop by 3mm or raise by 3mm to touch the straight egde.

Last weekend I have took the bath room tiles up my self and refitted them, I have used a metal rule across each joint to elimainate any height difference/lippage, whilst ensuring each tile sits level. I just find it difficult to comprehend why a tiler registered with the TTA was not able to achieve the same. If you want a job doing and doing well........., now I just need to make the best of a bad situation by replacing individual tiles. Very dissappointed. 😱(

I dont know what you do for a living but you have the makings of a good tiler!

this is incorrect i think as this is BS 5385 7.1.9.2 Across joints
There should be no appreciable difference in level across joints
(commonly called “lipping”) and the maximum deviation between
tile surfaces either side of a joint, including movement joints, should
be as follows.
a) Joints less than 6 mm wide, 1 mm.
b) Joints 6 mm or more wide, 2 mm.

It is 3mm on 6mm + joints Dean .. well it is in the updated version ..

 

[The D]

ok that is a lot lol

 

[The D]

It is 3mm on 6mm + joints Dean .. well it is in the updated version ..

can you post the update m8

 

[DHTiling]

It is as you say Dean .. could have sworn it said 3mm lol lol .. just checked.. sorry for confusion.

Is this not the second time recently that the 3mm over 2 meter rule has been taken out of context and applied to lippage:mad2::mad2:

Surprising end result!?! I'm wondering if this could be slumping in the adhesive? The amount of time taken would suggest to me that he tried to get it perfect. I've had it before, when you leave a job and it looks absolutely perfect, come in the next day and a tile or two have moved... Admittedly, this would be an extreme case!

Mmmmmm why are the TTA saying the tolerance for a lip is 3mm when it is 1mm????? Did you take the name of the person that gave you the advice ?

The above is correct across joints, this is where I got confused and please don't be offended by my understanding. What TTA are referring to here is tolerance allowed as you look down on the tile. Therefore if the joint is less than 6mm the maximum deviation in alignment as you look down on the tile is 1mm. Effectively if you had just laid the tile so it was still moveable, you could actually put your hand on it and twist it 1mm out of line and this would be within tolerance. This has nothing to do with the surface height of the tile against another tile. Believe me the amount of time I have spent on this is unbelieveable, even looking at regulations from the US and Australia for comparison.

The Australians have the best way of gauging lippage, they advise that by using a straight metal edge ruler from one tile to the next or protruding tile, if it allows a 2mmdrill bit to pass under it on the adjoining tile, this would constitute a rectifable defect. If the drill won’t pass under the ruler, the work is within tolerance.
