Stone flag grouting

[mikeyd859]

Hi guys.
I have been in the process of a jobs for a while. consists of a few rooms of tiling and a large floor area of large stone flags. the area for the flags is about 40m. I explained to the customer about expansion joints but are adamant that they don't want them (more because the male customer is an ex old school builder and he reckons he is always right). I have made them sign something to say that they are happy to go ahead without them and it was entirely their choice and reasons were explained my me why they need them.
My actual question is that the guy who supplied the stone said that it will be fine to grout these as I go along with my flexy addy. the falgs are only for the floors. there is an email to prove this. I cant say I have grouted with addy before. do you think this will work.??

cheers mike

Best to wait until there all laid and grout (with grout) in the normal way.

I can't see it's easier to grout with adhesive as you go as you'll have to clean up meticulously all the time to prevent serious tile hazing.

Christ no.

Grout after as normal.

What's their reason to grout with adhesive as you go?

What size joints have you got with the flags...

 

[SJPurdy]

purpose made grout or if wider joints traditional mix of sand and cement

also i would recommend sealing them before you grout up ..stone is porous and youll struggle to get residue

If they are thicker than 12 mm the best grout is tilemasters flexi grout mixed 1 to 1 with dry sharp sand,works a treat and we have used this in lots of jobs like that with no problems.

Sorry I haven't replied on this. been flat out. Was back at the job last week to finish up laying the flags. The customer is one of those who 'used to be a builder and did real well' so he tries to tell us how do lay the stuff. we have had a quiet word and he left us to it. Although he is still adiment that he wants the flags grouting with the PTB addy. I have got everything in writing for this to cover my back.

Another thing that you guys may find amusing- I have done 2 wetrooms for him and I told him that I could build a fall for him or get preformed trays (he has had all the floors screed levelled). I told him that I will need to machine plane the floors before they even get touched to lay on. with that he went and hired a sander and called me to say he has sanded the fall into the floors by leaving the sander running on the area and moved it slightly to create it, I just laughed and said OK (knowing it would not have worked). On returning to the job first thing I did was got the level out of the van put it over the 'fall' area. all he had done was created some 10/20mm dips in odd spots on the floor. he was not impressed when I told him that his 'fall' does not work/he has created more work for me/it will take longer to lay. luckily I am working day rate.

I've worked for a few of them type builders, very short term obviously.

Gotta be sealed if your using grout or addy
Ive grouted my utility with the addy, it is fine , been down ten years, but i wouldnt recommend it on stone , (or owt for that matter) and this was only a 6m2 utility in my house , just couldnt be assed going for any grout
