Best Way To Seal Grout For Glass Mosaics.

ApgarNJ

hey guys, just finished up one of my first big glass mosaic jobs on this addition we are finishing up. I grouted it last week and did a few other things on the job, now I need to seal the grout but not sure the best method for doing these 1x1 glass tiles. do they have a grout sealer that sprays on and then wipes off? in the past i have used a small sponge brush or tiny paint brush to just get the grout lines for bigger tiles, but there is so much grout to do, i want to do it the most efficient yet effective way for this type of mosaic. any help is greatly appreciated.
thanks
Dan

How big is this thing? Like 10'x10' or something?

I don't see why a sponge, a plastic cup to pour the sealer in and dip the sponge into and spread the sealer all over the tile and grout at the same time would be that strange of a way to do it. The glass won't be absorbing the sealer so it's not like you are wasting it, it will move around and get in the grout pretty easily. The sponge will allow you to soak up any pools and wring it out in dry places until you get it all sealed.

Buff it off with a few clean cotton cloths and that should take care of it.

I was afraid the sealer would leave residue on the glass tile that i couldn't get off.
it's about 6' long two person shower, that follows up the cathedral ceiling smaller than 10x10.
i'll try the small hand held black sponge brushes first, then have a larger grout sponge to catch any runs.

thanks for the help mike.
