customer callback

[stevee]

hiya lads ,long time since i posted ,but here go`s

been going 3 and a half years now and had my first callback regarding blown CERAMIC tiles,which has cheesed me right off

kitchen floor , green chipboard flooring,overboarded with 12mm wbp ply screwed 6 inches,then primed

loose wire heating ,no slc,tiled onto with topps trade rapidset flexi 18 months ago

9 months ago customer calls me to tile his bathroom floor,while there pricing it ,he mentioned a tile strating to lift in the kitchen,i looked and he said ,"i know u warned us the existing c/b floor wasnt great"

and we left it at that, now 2 days ago ,an email from him 2 tiles have blown,one cracked

im going to look on sunday and am prepared for a costly outcome for me...........

but a bit of advice would be welome befre hand please boys

how will i tell if its thermal shock from heating on too soon?

and where do i stand legally ,im preparing myself for cost of tiles,ufh and return of my fee if its my fault

im hoping it aint ,cos its not the whole floor.....thanks lads

Hi stevie, I have tiled on to heatmat once without slc and once was enough, I just can't see how you can get the right coverage doing it this way + its very messy! Don't accept liability so quickly, there are many reasons why it could have failed that are out with your control, could there have been a leak? Also you mention you have alerted customer to dodgy subfloor?... What did you say to them at the time? ... I know when its verbal its all worth nothing anyway but we have all heard the sob stories from customers in the past " can you not just do it bla bla" then you end up doing it for them knowing its not ideal

it may be down to my inexpierence at the time mate, the chipboard was looking old and had a tiny bit of bounce,which the ply did take out

there was a bit of board next to the problem area that i had to replace also noggin underneath

it would b nice if it was a leak ,as i remeber a blue polypipe under the problem area,below the joists

 

[Spud]

dont panic just yet go and have a look at it first

 

[stevee]

cheers gary, so any ideas for signs of thermal shock?

maybe it wont matter, he aint gonna hold his hands up to it

 

[macten]

Hardly any addy on the back of the tile and the slight bit that is feels like sand paper can be indicative of thermal shock.

 

[stevee]

thanks mate ,something too go on with,steve

 

[stevee]

right ive been and had a tile up today, 2 thirds of the floor has cracking grout,one third is fine

lifted a tile ,which didnt want to come easy[topps rapidset flexi]

i think its movement in the floor ,which i didnt think was as bad when i jumped up and down next to a glass water,when quoting

the addy seems to have come away near ply joints,awway from joints its stuck good on tile and ply,not just one or the other, warmup loose wire ,with their own green primer

im taking the whole floor up next week,and am probably gonna have to fork out over £700

i was hoping for thermal shock signs ,not that anyones going to admit to bad commisioning anyway

DAVE , u asked if it was onto joists , be interesed to hear yours or anyones views mate

im gonna takit on the chin ,[18 months into my career at the time] and put it down to expierence i reckon

Bit of a shame mate. This time check the floor is 100% deflection free, then glue and screw hardie/other cement board, then tile. Also in pic 2 it looks like you haven't back skimmed, make sure you do this time. Oh and take the ply out before all of the above!

This is why i do not like tiling direct to ply... too much cheap ply in the uk market and it can leach resin and this results in tiles de-bonding... you can see on pic 2 where the ply grain is embedded into the adhesive but de-bonded.. this is typical of cheap ply and UFH...

IMO you need to use a cement board to get a better bond... cover the UFH in SLC suitable for timber floors and then solid bed fix onto that.. making sure you back skim those tiles as well to create solid bed..

is the floor a floating floor, chipboard on to insulation, these types of floors can be very bouncy, and imo not suitable for tiling..

 

[stevee]

joists mate ,no insulation , thanks for your input lads,steve
