If you're really stuck, as I was one day, then B&Q sell an Evo-Stick
"sealant bead tool" which will do the job, just.

Hopeless Base also have something normally on sale with one of those
promotional video things associated. Very impressive demos but watch them
carefully, both sides of the sealant bead are smooth and flat, they
carefully avoid showing what happens if the tool encounters a grout
line...

It's a set of three(?) bits of soft plastic with various sized radiused
corners.
