Grouting Brick Floors
So, I did a few searches and couldn't find exactly what I was looking for so here it goes. I recently installed thin brick pavers (9/16" thick) over some Wedi board in my mudroom. The brick was installed in a herringbone patter with 1/4" spacers and the room is ~ 125 sqft. My questions have to do with grouting the brick.
1) Pre-seal or don't pre-seal the brick? I have been told and read about both ways, and I am concerned about grout on the very porous surface.

2) What would be my best option for grout for this area? I have used epoxy grout before, but never for brick, so I am worried about clean up. And I might not be able to grout it all in one sitting, so I am also worried about color consistency.

3) Due to not being able to finish in one go around, would pre-mixed (Mapei Colorflex CQ) be a good choice?

4) Having never worked with a grout bag or used brick tile before, how would I achieve a grout line flush with the tile? I don't want to tool it like how wall bricks have grooved mortar joints.

Thanks for any help in advance!

Make your own grout from Portland, sand and dye for color, if grey you can use mason mix and dye accordingly. Or I suppose you could use basic cement based grouts. Go through with your trowel and tuck pointer and let it firm up before stricking it off flush with the bricks. Brush for clean up, wire brush for anything stubborn and a sponge if need be to blend things in. If any haze develops do a thorough cleaning with diluted vinegar and water.

Interesting, I have never mixed my own with any dyes before. I don't think I am that skilled, hence why I wanted to use something with a bit more idiot proofing. I know that acrylic grouts, like the flexcolor, shouldn't be used in showers, but what about in a mudroom? It would never be submerged, but may seen some wet spots from umbrellas on the floor, or snow melting off of shoes and puddling on the floor.

If you have never grouted brick pavers before or have any doubt, use a grout release. I wouldn't mess with making my own custom grout color unless you have a lot of experience. This the recommendation from a guy who started tiling when there were only five colors to chose from.

We use to mix sand and Portland for Saltillo and pavers. We also used blasting sand and Portland. Custom makes Saltillo grout mix, not sure where to find it. It was easy to work with. It's gray in color.

Home Depot here has it.

Thanks for the recommendation on the grout release. I don't want grout all over the tile, so would a grout bag be the way to go then? Also, what would be the recommended grout type if I wasn't going to make my own? Like I said, I was thinking either pre-mixed or epoxy due to color consistency.
