Hi there, I am creating a wet room en-suite bathroom and and I have been advised to add an additive to the grout when grouting the wet-room tray. I suppose it is meant to make the grout more durable/waterproof? I haven't heard of a product like this and just wanted to know if any of you had and if you think I should go for one and if it would be helpful? Many thanks, Sel
