I've just had ivory coloured 60x60cm porcelain floor tiles laid and matching coloured grout, but most of the grout is already very dark due to work my builders had been doing. They weren't sealed. I don't think there's any way I'm going to be able to get the grout the same as when it was put in. I tried soap and water and also vinegar but doesn't make any difference. I'm definitely going to seal it so that it becomes water repellent and dirt proof, but I want to know if there's also any good product that I can stain it with in a similar colour before sealing it?
I saw a youtube video of some american product which is an all in one stain and sealer, with a choice of colour stains. Is there any such product here? If not, what two products should I get? Lithofin KF Grout Protector 500ml was mentioned in an old thread as being very good, should I get that? The product description says "The appearance on the surface is not altered; it may however become slightly darker." Maybe that's the same with all sealers? For stainers, should I get a stainpen or are there cans of grout stain to buy? If I can avoid regrouting it would be easier.
