Slate Tile Help (Possible nightmare)

[Unregistered]

Hey all,
in a situation at the moment, I work out the country and basically moved in a new house and have been getting building works done etc when i was away.
Anyway I was getting black slate tiles fitted in my kitchen, when i came home he had left word with my girlfriend the job was complete but all that needed done was the slate tiles cleaned and sealed and left the bottles for the job to be done by us (Strange, yes i know).
Anyways when i came home the tiles were heavy white with obvious grout residue so i followed the instructions on the bottle of the HG grout/stain remover to begin cleaning the tiles. Took me about 4/5 coats of this stuff before the tiles actually became normal.
After this i allowed a few days before sealing with LTP colour intesifier natural stone cleaner. Again i followed instructions and allowed to cure with more than enough time.
Now after all that it seems when im getting a splash of water on the floor or walking on the slate with say bare feet that sometimes like the outline comes up with the heavy white kind of grout stain again, ive tried to clean with clean water but the stain comes back to the white patch as before.
Totally not sure where to go from here any help will be much appriciated. Ive spoke with my gf who quickly poppped her head in etc when he was working away and had asked her if he sealed the tiles before laying she doesnt think so, could this be the problem?

[jay]

any chance of some pictures of affected areas
was it lptcolor intesifier natural stone sealer (or impregnator)

Ill get photos in 15 mins of affected areas and product, camera out of battery just charging it.

Thanks again

Hey pics as posted

<< Seleant

<<< Staining



bit of further info spoke with GF on phone and she said when tiler was leaving he told her to used flash to help clean the floor aswell.

[jay]

can you walk me through the steps you took to seal if you dont mind and how long did you leave floor to dry before sealing thanks

[Hoggins]

Basically when i had come home

The gf had tried cleaning with flash and then put on one coat of the hg grout/cement remover on the tiles.

When i came home the tiles where still drastically white and dusty of i continued with maybe three 3 more coats of the hg stuff following the instructions, apply, then clean off with wet cloth. left around 3-4 hours between applying the coats. The once finished last coat wiped off etc i left for at least 24 hours.

I then began to use the sealer above and again followed instructions of use and left around 6-8 hours between coats applying 2 overall.

looks a lot like there has been moisture trapped under sealer causing it to go white (think they call it blooming over there )could be some sort of chemical reaction due to the flash used (not something id recommend ) i could be wrong but i think it needs stripping back then cleaning then let dry about 48 hours then re sealing

sorry not the news you wanted
others will be on soon they might have better answers good luck

Cheers for the information.

It seems its only some of the tiles though, ive tried to like splash some water on some of the other tiles at the backdoor to see if the same reaction happens but they seem to be fine.

Ill see what the general consensus is, then ill probs troop off to get more tiling products

Next time im finding a tiler on here, surely any tiler coming to do a job should finish it start to finish from the laying to the treatments or am i way off the mark.

Incidentally i cant get hold of the tiler i got to do it.

[jay]

the tiler should complete the job including sealing if you need a tiler in future list it on here there are some top notch tilers and only reputable ones will contact you good luck

[Yorkshire Tiling Services]

That looks like water staining !
As mentioned,probably trapped beneath sealer.

[paul flight]

did your tiler use a rapid set adhsive ??? or slow set?

[Hoggins]

Cant answer that question paul as i was out the country at the time of them being fitted.


Got hold of the tiler today and to his credit he was quickly apologetic about whats happened but is unsure whats happening. Hes took a few sample spare tiles to have a look at and will get back to us.

Hoping its nothing major cant deal with this going badly esp when my house is like a building site at the mo with all the other guys working away

[doug boardley]

my guess(es) are

1. trapped/sealed in moisture.
2. maybe you missed some areas when sealing (long shot I know!)

[Ken Bruty]

Also some slates don't work well with certain products ie calciferous slates, if you put sealer on the bare slate and it fizzes (try on a sample piece) then that sealer is definitely not suitable for that slate, and should not be used under any circumstances.

[Hoggins]

im thinking its possibly the trapped in moisture as im sure i covered every inch of slate.

Ken i tested on small patches behind a internal cupboard door before doing the rest and the sealer went on ok no fizzing etc.

Ill let you guys know the outcome from the original tiler as soon as i hear.

I appriciate all the help coming btw
