Stain stop plus over grout

[Flintstone]

I haven’t used this product much before, I usually use the regular stainstop, or universeal. My question is, how does it go over grout with it having the colour intensifier in with the sealer, will it change the grout colour ?

yes.
i'm using it soon to darken a grey floor grout which lightened after too much water in the wash-up.

I’ve sealed this stone prior to grouting with plus. Might have to be normal stain stop then for the second seal after grouting !

You can use regular stainstop for the second coat.
