Sealing grout in the shower

[MikeR]

I have just had my bathroom tiled. Looks great. If I polish the tiles with "Mr Sheen" and some of the polish gets on the grouting would this help seal the grout against absorbing water around the shower area. Or is this not a good idea.

Have a look at

for Lithofin KF Grout Protector. That will do the job for real ;-)
