LOl at these answers. Sorry it's taken me so long to reply. Birthdays, xmas, and obviously a lot kitchen floor scrubbing. Anyway, perhaps it is excess sealer as my hubbie did the sealing. They are Kerapen porcelain tiles, made in
Spain. They say frost proof so maybe they are also suitable for outdoors (though they are quite thin). They are a tiny bit abrasive. I got them from Al Murad tiles on the A12 near Redbridge. They told us to seal them as did the builder. We used HG sealer. It did make the floor look lovely, brought out more of the colour. And before, when I mopped, you could see the mop marks when the floor dried. The sealing has stopped that happening - though to be honest, mop marks are better than difficult to remove dirt.
Would this be excess sealer? I can see now (after a good few scrubbings) patches where the sealer seems to be coming off. I was worried that the sealer was completely coming off, but maybe it's just the excess. I also bought some stainguard? Haven't used it yet? Would you recommend I don't? The tiles do get a lot of dirty traffic as they come right off the garden and also the sink/ cooker area which always gets filthy.
Thanks so much for your time. And yes, always do what your wife says!!
