Dot & Dab travertine?

[The D]

dont be silly
i know fack all
i just do the job and use my brain

i dont have to achieve sales targets and pacify sales managers

Pj I am not picking a fight with you at all but is the spot method in the original pics (three spots on a 600 by 400 travertine slab on to untreated 12mm plasterboards acceptable in your judgment)

if you read the tread youll see i roundly condemned it !!!!
that jobs a disgrace
i was only trying to educate the dot and dab disbelievers to the fact that some jobs offer no alternative

I do know what you are saying I’ve been in this game along time as well the work you are doing is highly specialised and I am sure well thought out but some of the less experienced tilers reading the thread will look at your pics read that it is ok to spot fix and of they go to the next poor spanky

this poor buggers just been unlucky tough but it happens
and i hope he gets it sorted
had i done the job i would have cerated & primed
looks to me like the contractor was useing chancers
cutting trav with an angle grinder says it all

I am sorry if I have upset you your tiling looks very nice but looks aren’t everything

It's whats inside that counts

theres no way there going back to sand and cement
the adesive reps have all but brain washed every bugger in to thinking they know best
well ive got news for them and you they dont

The 3 porblems with d&d are.
1. The risk of exceeding the bedding depths. 6/5mm, 10mm in isolated areas. this can result in the adhesive exsesivly shriking. As I said I looked at a failure yesterday of 800x800 tiles on a wall, where the thick bed of d&d adhesive had shrunk, and caused the tiles to debond.

2. You need to make sure you're getting 100% (or there abouts) coverage in wet areas, and 80% elsewhere. This is to be able to support the weight of the tiles.

3. The BS says weight limits of 20kg psqm on plaster, if you have a 12mm stone fixed to 5 or 6 dabs of adhesive, then you are far exceeding your weight limits.

If you can d&d, and overcome those REAL issues, then good luck to you. I'd rather see the walls made good, and serrate away.

This isn't from an adhesive rep. Its from a tiler of 10 years, who as always seeked to improve his knowledge, even if it means eating a few large slices of humble pie. Which i have done, and continue to do.

Reading that last post has made me rethink an idea that may negat the need to remove all the tile?

Is it possible to inject adhesive through the grout gaps behind the tiles?

If it is possible, how, who, etc etc

Seems feasible?

Could save £3000 worth of work?

A very interesting point spanky.THis is just for general interest.There is a method i know of that a greek tiler told me about some years ago,this was also used on swimming pools.Hold onto your hats for the backlash of this!!!
tiles were stuck on to render with D&D, at the end of each day they make up a slury and put it in a watering can,they then pour it down from the top of the last course of tiles to fill all the voids.
greeks eh what do they know about tiling. if only they had Brithish standards three thousand years ago.

3000 years ago they bedded onto a solid bed. Thats why the things are still around today.

The guy is not leaving any voids this way, so maybe that would work for a swimming pool.
Once again it seems a lot more hassle than just getting the walls right in the first place.

If that was an adhesive manufacturer's motive, they'd say 'bed away'. If you're bedding out over 6mm to make up bad walls, then the sales manager can reach his sales targets quicker. :yes:

Help me out.ive searched everywhere but cant find any mention from anyone saying they dd all the time.And havent some people aready said british standard is best used as a guide rather than gospel.Cant find any reference of any calling anyone a fool either.If someone would like to set a benchmark,something along the lines of how long bal gaurentee blue star for then we can look for proof that dd is good for that length of time.

I think you will find that the British standards are the benchmark.

oh well i had,nt realized you got all them years in the trade
i wish now i had sort your advice before i started the job
Alas i went to the technical department of one of the leading adhesive manufacturers in the world (who sent one of there guys for a site meeting and agreed the proposed method of fixing ) at the meeting were the main contractors structural engineer,the architect, site agent,and the client
all of which have done similar jobs all round the world for 40 odd years
next job of a similar nature i promise to seek your advise as I'm sure your ten years experience would be invaluable
there is one thing you could help me with (im kinda set in my ways) should i stop organizing these 50 k jobs on the back of a *** packet with my oh it,ll be OK attitude
or should i handle it in the professional manner i have for the last 45 years

Why do you feel the need to revert to personal attacks?
I'm trying to make a point, that I'm not some 'rep', reading from a book.
Yes you have a much greater experiance of fixing than I do. If you've had an adhesive tech guy see the method you're fixing those tiles, and there happy so be it.
As I said earlier. If you can get the right amount of coverage, at the correct bed depth, then I can't see it matters how you arrange the adhesive behind the tile.

I think we should get back on track forget exterior cladding it is a different subject we are talking about the domestic application of large format natural stone.
