How to Apply Grout to Tile with a Dispenser
Normally you would grout a tiled area by wiping the grout across the newly laid tile surface with a grout float (a flat rubber trowel), pressing it into the spaces between the tiles, scraping it off the tile face, and wiping it all down with a damp sponge. But unsealed tile or natural stone will stain if grout gets on the surface, so you need a different approach. One way of dispensing grout is to use a grout bag, which operates with the same concept as a pastry bag, allowing you to aim the grout in the lines and nowhere else. Does this Spark an idea?

1
Pour about 2 inches of water into the bottom of your bucket. Add enough grout powder to cover it. Use your drill's mixing bar to blend it completely, adding more water and powder as needed to make about a gallon of grout, at the consistency of thick mud. (If your project requires more grout than this, make it in separate batches.)
-
2
Allow the grout to sit in the bucket for 10 minutes. Stir it again with the beater bar. Pour it into the top of your grout bag, using your trowel to help guide it in.

3
Place the tip of the grout bag onto one of the joints between the tiles, starting at one end of the span. Squeeze the bag while pulling it backward, so it expels the grout into the joints. Grout the joint in this way for a few feet, then grout the other joints around it, in a section as big as you can reach from one position.

4
Run a damp sponge it lightly over the lines in the grouted section to smooth out the grout and clean off the tile face. Repeat for the next section. Do the whole surface.

5
Allow the grout to set overnight. Use a stiff broom to lightly brush the grout lines, removing any residual power.
