Black porcelain tiles with grout specks!

[stu247]

Hi I previously posted this in the guest area, so apologies if you've already seen it, thought I might get a bigger response from here!

I have had some black polished porcelain tiles installed floor to ceiling (including floor) in my bathroom. The tiles were from tiles2go 600 x 300. The tiles were sealed with LTP MPG sealer, 2 coats, polished up with a professional mechanical polisher and lambs wool bonnet. The tiles were then grouted with BAL Microflex (white) on the walls. The grout has filled the micropores on the tiles leaving tiny specks of grout all over the tiles. I then purchased some LTP Grout stain remover, applied diluted at varying levels, which didn't work. I then tried undiluted scrubbed with white emulsifying pad which has shown an improvement but after 3 scrub downs specks still remain. Following me strangling the missus for picking these tiles any advice would be greatly appreciated. I presume I'll need to re-apply sealer following me scrubbing down with the acidic grout stain remover? Thanks Stu

oooooh a lot of grout specks..

On one tile that is in an area not so noticable...try the cleaner neat...leave it to dwell longer and keep agitating it every few mins.... try that on that one tile and see what result you get....use a stiff hand brush to work it in..

Thanks again will try that now. Am I right about re-sealing after scrubbing down the affected tiles?
