problems with 600x600

[jay]

So the tiles have lifted away from adh

 

[DHTiling]

yes to bed tile up

The thing is though , if you exceeded the recommend thickness and also had hollow spots, then you lose tensile strength.

nano is supposed to do 20 mm

 

[newmantiling]

the problem i have is l do not have problems with any other adesives

 

[DHTiling]

I thought it was 15mm.

What size joints did you use, ?

Was the tiling to skirting or under. ?

Still yet to say jf you skimmed the tile backs to fill in the profile.

the problem i have is l do not have problems with any other adesives

And just to add , we have heard of probs with that brand, might be worth a tech cal out.

largest area 7mx4m but total area about100m ufh was up and going

:welcome:Are the majority of lifting tiles in the 7 x 4 area? if so then Daves right too much stress and not enough room to expand. Skimmed on the back of the tiles could of helped prevent it. But that large area really needs to have an expansion joint. Did you grout the perimeters or Silicon?

 

[newmantiling]

3 mm joint under skirting flit backed tiles

 

[newmantiling]

movement under skirting

 

[jay]

May i ask why no other expansion joint

 

[newmantiling]

any problems l have had in the past few years have been with this adesive

 

[newmantiling]

l did recomend them but owners declined

 

[jay]

l did recomend them but owners declined

The owner has employed you to fix the tiles ,and should of been guided by you ,lack of expansion joints is part of the problem , unless you have it in writing that the expansion joints were not allowed by owner you may have to wear this one '


Sorry if i come across a bit blunt but expansion joints are not optional

 

[newmantiling]

been on a site visit today lifted some tiles adesive has hairline cracks in it

 

[DHTiling]

You need to call PCI out.
