    I've just regrouted my shower using Mapei buildfix flexible wall & floor grout. The joints where raked but not completely dug out, the original grout was old and discoloured but had not broken away just needed freshening up, do I need to seal the new grout joints as the grout? Below is the info on the grout.

    You don't need to seal grout. its not waterproof but its more than capable or repelling the water.
