Border tiles fixing(one method)

[Peter]

I'd use tubbed adhesive for kitchen splashbacks, usually so that I can get myself a new clean bucket out of it. Don't really think it's the job for bathrooms though.

My reason for this is that I done inside a plastered shower in 8x12 tiles using a well branded (customer supplied) dispersion adhesive. Primed and prepped properly (although no tanking) and thought no more about it. Got a call about 2 years later saying that the tiles had bowed and to come and have a look at it. Pulled a few off, expecting coverage to either be 100% wall or 100% tile. Found that the adhesive itself had broken down, and there was soggy adhesive on both the tile and the wall.

Other reasons for not using it are that I can get a 20kg white flexi bag for the same price, and that it's slippery and slidey and hard to wash off things.

Nice job there mate....... Have to agree with other guys on the addy only use powder its cheaper and a better product once you get above 30*30 you should only use powder they looked a lot larger

right to clarify i phoned the tech department up today and explained everything to them about this job, their answer was that the adhesive is more than upto the job and their is no problem fixing with it. the only downside they said was that it might take slightly longer to 'go off'. after all its only a recommendation advice they give in the data sheet. the fact that it will take slightly longer to 'go off' is an advantage in this case which will help if the border needs corrected or some removed off the sheet if they werent sitting right on it. i took some measurements today of the gap between the fixed tile and the plastered wall and it was 3mm, i used a 8mm trowel as i do at a angle which put about 5/6mm depth of addy on the tile. which obviously when twisted and pressed on results in a approx 3mm bed. tile size was 240mmx390mm which is 93.6cm2 compared to a tile 300mmx300mm which is 90cm2 so overall difference in area is 3.6cm2.

Sean - I'am sure that the members who have supplied their views are appreciative of your thread and the 'look' of the completed work.
Although there is an issue with the type of adhesive used on the stone border and tile size, you have certainly done your homework retrospectively with contacting the technical department of Mapei and you can understand why there is a small range for concern.
Well done for the thread!
