You can use more or less whatever you want - as long as it's a jointing material. Mapei is good, Larsen less so. If if you want a finer, smoother finish, then a tiling grout is the way to go, but a paving grout such as Ultrascape is perfectly suitable if you don't mind the coarser texture.
And then, of course, there's nowt wrong with the traditional 4:1 miix of sand and cement!
