Hi , firstly , if the customer had bought an impregnator , there will be no shine, if the tile is matt the tile, it will be matt after the correct application of any impregnator.
test one or two stones, you may have a light polymer smear on this tile as well as a grout residue, from us test lithofin power clean 1-3 with a white pad 5-8 min
if it struggles to get through seal , stripp two tiles with wax off then try the diluted power clean again.if this works dry floor 4-5 days and re-seal with the imp- no shine!!! if still issues put some pics on here , for us to look at.

Ive been to the job and tried a sample of LTP solution which the customer picked up. I went over 2 tiles and hand scrubbed them and they came up perfect. I will be picking up lithofin power clean as mentioned as im used to this product from floor restoration which i did when i first got into tiling. This is why previous comments from certain people were naive and just completely negative. Most things can be rectified!!
Is it adviseable not to use a different sealer afterwards? We started with Fila but i would prefer to use Lithofin.
Thanks again for your advise. That was the sort of advise i expected from a site like this.
Cheers
