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]

You need to call PCI out.

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

did you take any pictures ?

 

[Gazzer]

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

Heating on while tiling ?

 

[Perry]

did you skim the back of the tiles ?

 

[newmantiling]

did but they blamed tiler for some tiles not been completley solid bedded

 

[newmantiling]

i did but cannot show them yet

 

[newmantiling]

no heating off for a week before tiling

 

[Perry]

having used a lot of nanolight skimming the backs and the adhesive has de bonded other than have dust or something on the back of the tile its hard to understand

 

[newmantiling]

why would the adhesive have that has been screeded on the floor have hairline cracks all through it

 

[Perry]

depends how deep it is

 

[newmantiling]

no more than about ten mm

 

[Perry]

how was the heating turned back on pics would help

 

[Perry]

PCI are quite good if its a problem with there adhesive they will stand by you unlike most other big names but they supply through someone else in Ireland not sure about the North

 

[hillhead]

There's not too many PCI distributers here in my neck of the woods.
I did use plenty of it a few years ago on a big appartment block south of the border with no problems reported.

 

[newmantiling]

a few years ago this adhesive was ment to be the best but i have had a few problems in the past few years all involving nanolight no problems with any other very fustrating

 

[jay]

pics of the cracked adh might help

 

[newmantiling]

no picks of cracked adh very fine but visable leads me to think about underfloor been put on to hot to quick

just a little addition to this,
at a fairly recent adhesive companys trade evening,when asked by quite a few tilers about polished porcelain tiles debonding from adhesive,their answer was ,that the companies know that a problem exists with adhesive not acheiving a strong bond with the tiles ,due to the density of the porcelain,and the fact that the adhesive bonds to the primary surface ,ie the screed,so when you lift it wet,it seems fine ,next day lift it and tile is clean,as the screed has sucked in the moisture,that is what they told us.!!!!!
ive been thinking this for yrs

priming the screed or concrete would help

 

[deankyall]

yep thats with priming,just knock a tile back up when its dry couple days later,ive seen it it dosent stick to the back,i started a thread on this about 8 months ago after asking lots of tilers in my area ,and almost to a man they had experienced the same thing?????,seems wierd that adhesive companys know there is a prob,,but keep qiuet!!
