What materials would be best here?

[veedee]

Just finished tiling my kitchen. Having fitted the sockets, I've noticed that i have a gap between my cooker switch and the tile (i.e. Where the grout would go

Now if i simply put some grout in the gap, it will all slide down

So in this situation, what can one do?
