Use a rubber edged grout spreader. Theyre only £1 or 2. Slop the grout
onto the tiles and run the spreader all voer to get the grout into the
gaps. Go over it repeatedly to push it in well. Wipe grout off the
surface by moving the spreader at 45 degs to the gaps, this leaves
nice concave grout.


Yep - you can get a fairly rapid rate of fill that way. And a decent
(but not expensive) rubber "float" can take 95% of the excess off the
surface making cleanup easier (see below).


Do I fill the horizontals first or the verticals? Or does it not make no
difference?


theres no distinguishing, just slop it over everything.


That's how I did it - do a m2 at a time or so and keep an eye that it is
going well (ie no missing bits).

Then after 1-2m2 depending on your speed and the grout type (I'm basing
this off mix it yourself Mapei Keracolor) it will be firm enough, but
not too hard to sponge off.

Now take a bucket of fresh water and a nice big cuboid tiler's sponge,
wipe gently with a slightly wet but not dripping sponge *on the flat*
(ie not at an angle) and using several passes and rinses leave the tile
face clean ish (no lumps, but haze is fine). Depending how long you do
this or how wide your joints are, you can control how much you recess
the grout line.

Leave the haze - it dry polishes off later.

Note - this is for regular grout - epoxy would be a different kettle of
fish (I expect).


Epoxy is much the same: use a stiff heavy-duty grout-spreader, epoxy is
harder to spread and you probably want to work a smaller area at a time. To
clean off use a scotch-brite type scouring-pad and water in addition to the
sponge.
