Black Galaxy tiles have gone patchy after sealing

[shirleyali1]

This problem has been going on for months now and is driving us crazy. We had a conservatory floor laid with black galaxy tiles. The tiler did an excellent job in laying the tiles. He grouted them the same day and cleaned them off to a degree. Several days later another man turned up to seal the tiles. It was a red hot day and he sealed the tiles in about 20 minutes. We asked if it needed cleaning off before it was sealed,he said no it was ok. We were told to leave the sealer till the next day and then wash the floor. The floor looked awful with loads of patches, some running in places through several tiles and it looks mottled now, nothing like the tile we chose.
We complained to the company who were very aggressive, but eventually said they would return and seal the floor again, when it was cooler. This they did 3 days ago, telling us to leave the floor till the next day again and then clean it. It looks worse.
Please can anybody suggest what to do. We paid a fortune for the job.:mad2:

Hi shirley...sorry to hear of your dilemma........do you know which sealer they used..?....

Thanks Dave, but we don't know which sealer he used, it was just in a plain plastic bottle. Do you think that the floor not being cleaned before it was a sealed, caused the problem, plus could we have the sealer removed?
Many thanks

unless you know what sealer they used this is difficult question to answer some sealers are whats known as impregnators which go into the pores of the stone others sit on the surface floor tiles that need sealing should be clean and dry before sealing most good tilers give the tiles one coat of sealer before laying one coat after laying and a third after grouting but it all depends on the type of tile type of sealer etc

Yes!! shirley if the tiles were not clean then the sealer will lock the dirt in....and could have caused the patchy drying.....

Is it possible to find out the type of sealer used..?

This could be a case of the wrong sealer used as well.....but we would just be guessing till we know what we are dealing with.....

Will try to find out what sealer was used, but the company are not the best to deal with. I'm almost sure he said that the sealer soaks in to the tile. Do you think anything can be done, if it has had dirt/grout soaked in as well.
Thanks

It can be sorted.. no probs shirley..don't worry about that.....would be good if we knew what it was sealed with......can you also post pics of how bad the tiles are...then we can give direct advice as the best way to handle it....
sorry for this but we want to get it right for you.......

Sounds a right mess.

Was it a national tile shop that fit them for you ?

As I would see this there are 3 possible issues :

It is unusual for granite to be sealed 3 times as over 80% of granite needs no sealing because the absorbtion of granite is very low in deed. Keepin this in mind it could be that maybe too much sealer has been left on the surface and dried there giving a shading effect.

Granite as you know is natural and it is not uncommon for differing areas of a slab(that the tiles are cut from) to be denser than others. If this is the case then possibly you have areas of tiles which have and areas of tiles which havnt absorbed sealer so giving shading.

If the granite was laid and grouted relatively quickly the adhesive below could b still be disspersing moisture in some areas. This moisture can effect the tile in that you would get a shading effect untill it dries fully. If this is the case then the sealer is not helping.

Every natural install is different and with granite being sourced just about everywhere quality varies and so its near impossible to pinpoint exact problems. As the guys have said if a start can be made with the type of sealer then it would be easier to advise.
