I recently completed the tiling of a small half-bathroom in my house and was wondering if I should seal the grout or not. The bathroom gets a lot of use during the day and I'd like it to look as good as possible for as long as possible.
The tiles use are a white/bone colored porcelain mosaic, American Olean - Chloe I think is the name. Grout lines are 1/8 inch and the grout used is unsanded, white in color.
I've seen some people insisting grout sealers are necessary and others that say they are nothing but marketing hype. I don't mind applying a sealer if it will make a difference, but don't want to waste my time and money unnecessarily.
So, I'd like to hear opinions as to whether I should do it or not. Also, if people are in favor of grout sealing, recommendations to brand, application type (brush on, spray on, etc.) would also be appreciated.
