Painting a garage
Discussion
Spraying would be the quickest method of application but the masking up may negate any time saving.
I'd go for a deep pile roller personally seeing as the surface is presumably pointed brick.
Regarding emulsion, you get what you pay for. The cheap stuff will take coat after coat to get good coverage. Go for a brand name (Leyland, Dulux, Crown) and you'll probably get away with 2. Might even be worth considering a masonry paint.

Did this last summer for my sisters Garage, simply went...
1] Empty the Garage of every thing including benches.
2] Sweep down the Ceiling and walls with a stiff yard brush.
3] Sweep the floor.
(this only took 1.5 hours)
Then have a cup of tea
4] Budget Bucket of white emulsion Paint (B&Q, Homebase, doesn't matter) and a Large Brush. I used an old wall paper brush.
5] get stuck in!
6] clean up and big spills of paint off the floor.
(this took probably another 1.5 hours)
Have another Cuppa and a bit'o'cake
7] Sweep floor again
6] Use a large Roller on a pole and begin painting the floor
(from the back towards the Front door
classic)
Again I used a tin of grey workshop floor paint from the local Screw-fix, just make damn sure to read the instructions on the can.
Some require a great deal of thinning down, which was discovered at work when they painted the concrete stairs before a Customer Visit without reading the label
Customers had to use the fire escape 4 DAYS after it was applied 
Leave the paint to Dry overnight if possible.
It took me about 4 hours in total (including coffee
) starting at 8am and finishing for 12-ish.
