Exposed edges of tiles slightly visible after grouting

[Yaglaser]

In answer to your kind questions:

I think a few more pictures of offending tiles would help a bit more...

The other tiles look like the ones in the picture posted earlier.

as you said they're in the shower area, was it tanked prior to tiling?

Yes, a BAL shower kit was used.

From one pic its hard to say was there any waterproofing what is the substrate and what adh was used is it a shower area and finally do the tiles absorb water (may cause pic framing)

Waterproofing = BAL shower kit

Substrate = plasterboard (skimmed)

Adh = BAL Green Star (I asked for White Star)

Is it a shower area? Yes and there are exposed edges (like the one in the photo) in the shower area.

Do the tiles absorb water? I don't know: the tiler told us not to use the shower until next Tuesday.

Picture framing? Sorry, I don't know what that means.

you cant expect more advice unless you let people see the job yaglaser...simple as that

he shouldn't have used the green star, it's a dispersion adhesive and will break down if it gets wet. he should have used a cement based adhesive

 

[kilty55]

agree with mike cement based would have been better what size were the tiles yaglaser?

 

[jay]

pic framing is when water is obsorbed by the exposed edge of the tile causing the tile to change color around the edges .Oh no not tubbed stuff on waterproofing:mad2:

Thanks, once again, for your replies. Regarding more photos: which sort would be useful? Wide angles or more close ups?

All the tiles were used up, I'm afraid; so I can't supply any photos of loose tiles.

he shouldn't have used the green star, it's a dispersion adhesive and will break down if it gets wet. he should have used a cement based adhesive

I thought this, but, according to BAL, it's okay for use in 'domestic showers'.

 

[kilty55]

hi glasser,just an assortment of pics of the whole job and some more of the wet area in particular will help us advise you.......

 

[White Room]

More of a wide angle or across the tiled wall...

 

[Yaglaser]

agree with mike cement based would have been better what size were the tiles yaglaser?

The size is 150mm x 150mm.

I will take some more photos of the type you suggest. Need to go to bed now, so will post them tomorrow. Thanks for your help, everyone.

Will have to eat my words seems the manufacture recommends it over waterproofing (new one on me) http://www.google.com.au/url?sa=t&r...2amnDg&usg=AFQjCNE5U6Xa3Z2e-9r8LzHbwyQVpw-pVA

Still would use a cementitious addy.

Was always told dispersion adh were not suitable on tanking ,go figure

 

[Andy Allen]

i thought that to..

 

[Mike]

i wouldn't use it in a wet area as we all know it breaks down in water. there's all sorts of products out now that manufacturers advise using for example ready mixed floor adhesive and ready mixed grout, but we don't use them.

 

[Andy Allen]

where did you get the tiles from, were they cheap tiles from one of the d.i.y sheds?

 

[Fliselege]

Is the offending tile a cut installed the wrong way round?

 

[Stef]

By the looks of the tiles i dont think it would matter if you did get a fuller grout joint as the glaze doesnt go far enough round the tile,
I see this all the time with tiles, Not just cheap tiles either, I think you will just have to live with it.

Regards the adhesive used, Although Greenstar states "Dry Intermittent wet environments" "Domestic Showers with a water proof grout" i would never use this in a shower as it will break down with water & will fail.

Did the tiler use an Epoxy grout?

If he wanted to use a dispersion adhesive then the very least he should have used should have been Bal Whitestar,
This will not break down when in contact with water.

Missed that bit re epoxy grout that would explain why they can recomend despersion adh on tanking . Thanks Robson

 

[swanman]

Agreed as above

Jay we use Greenstar all the time with 1 housebuilder we do work for,
They use Plastic shower cubicles so the greenstar is never used in a shower but it is used round a bath. :mad2:

I have spoken to them on a number of occasions but they state, "we have used it for years & never had a problem" :mad2:

Until we get a major fail then they wont change their ways, on saying that though they are eventually starting to listen to us, I now have the MD phoning me asking for advice when they are tendering for new work so its a step in the right direction.

Getting back to the thread, We are seeing more & more tiles where the glaze is stopping almost on the face of the tile & not wrapping sufficiently enough round on to the side of the tile, It doesnt matter how much grout you use you will never be able to cover the biscuit.
I try to advise people when they are buying tiles to check for this as its becoming a pain.

Cheap tiles bet there either Chinese indian or Brazilian. Like i say you get what you pay for. Why did the tiler fix if they were that bad? Silk purse out of a pigs ear?
