Never used it but what I can say IMO is a lot of people misunderstand the purpose of sealing grout. no grout sealer prevents water from passing through if your grout is cracking or will down the road for what ever reason sealing will not stop it. what it does do is keep dirt and yucky stuff out.
Q: have you sealed that grout before? How old is the grout? Some of the new stuff on old stuff doesnt work well...imo
