Sealing decorative (small) tile

I'm working through a tiling project on a bathroom and the tile I've chosen is a 'flower' pattern. The tiles are each 3/4" hex tiles attached/glued to a 1'x1' netting. The installation has gone OK, but a question on sealing the grout. Because it's in a bathroom, sealing is mandatory (I'm assuming), but I'm wondering how to seal the grout. I've read articles and instructions on line, but with my particular application it would take me forever to carefully apply sealer around each 3/4" glazed ceramic hex tile without getting any/minimal on the tile itself. Is there a recommended way to do this that provides an effective seal without 30 hours of painstaking work. (I'm taking this project on as a DIY, with some help with someone with experience laying tile, but he has never worked with this type). I've seen the multiple posts on the spray sealers (and resulting trips to the ER), so wondering if there are options that would be efficient. Any thoughts or suggestions would be appreciated. Thanks much!

Brush it on or sponge it on, then wipe dry the tile with a paper towel before it dries.

Yup!
