Damp marks showing through tiles

[AnnMcCarron]

Hi

I've just had my bathroom tiled in white matt ceramic/porcelain tiles and today I noticed shadow spots on all the tiles. The tiler explained that it's the moisture from the adhesive coming through the clay back of the tile and that it will dry out. I'm not confident with this answer because 36 hours have passed and the tiles still look the same. He's coming back tomorrow to grout and I'd really appreciate some advice on whether or not these shadowy stains will indeed dry out and if not what action needs to be taken. The adhesive is white Larsen standard wall tile adhesive.

Thanks
AMcC

Hi and welcome....does the moisture spots look like spots, any pics would be good.

Ahh damp spots... so spot fixed... tut tut..

What adhesive was used ? And as Dave says, sounds / looks like possible spot fixing of tiles. Did you watch your Tiler work, how was the adhesive spread / applied ?

Please see photo below. Not great light but sots best seen in the area of light reflection. Will they dry out. Tiler came with a plumbing team recommended by a reputable bathroom showroom.

From what saw he fixed the adhesive to tile then tile to wall, but the tiling I saw him do was more or less full coverage of the til.

Is that adhesive ready mixed or powdered? Not one I'm familiar with.

It is spot fixed.. but at least he has tried to get good coverage.. most do the 5 spot technique.

Dot and dab, what a delight

 

[AnnMcCarron]

The adhesive is powdered. Will it dry out like he said?

Possibly, but I'd have thought that after 36 hours that should already have happened.

nothing wrong with the adhesive he used and it looks like a tidy job. Just fixing method leaves a lot to be desired.

That said I can see trowel marks through the grout joints so whilst it looks like dot and dab from the marks i'm not 100% convinced myself.

i've only just realised that's a floor. I thought it was a wall :lol:

To the left of the photo the pattern follows thru on to the wall.....

a wall with an extension lead magically stuck to it :lol: to be fair the OP did mention walls in one of the posts!

 

[Mr T]

could this be the quality of tile chosen? looks like theres spread on the wall?

 

[Mr T]

is it really a floor? them ay floor tiles am they?

 

[Peter]

Looks like the tiler has spread the floor then spotted on top of that.

That would mean the extention lead is levitating.....

It's just an odd angle to take the pic from, either the op is spiderman hanging from the ceiling, or they really stretched over so as not to get their feet in the shot :lol:


Ann I reckon your floor will dry out but if it was dot and dabbed as it looks then your floor has weak spots in it and is more likely to crack under pressure than if it was solidly fixed

just noticed lol

 

[Mr T]

the pattern of spots looks the same on each tile to me wich would suggest it is the tile... or adhesive has not fully set.. but may also be my inexperience

 

[AnnMcCarron]

It's a wall! The photo has appeared upside down on the site. I'm no expert on tile quality but we paid £*** pounds for aprox 7mtrs sq. The tiles are 8mm thick.

 

[Colour Republic]

here we go... that makes more sense now :lol:

The quality of the tile isn't the problem here, it's the fixing method. There is fairly good coverage on the tile judging by the spots but, if the marks don't dry out it'll have to be done again.

 

[AnnMcCarron]

Sorry.

Thanks Bri. Fingers crossed it dries out.
