Does the job very well when grouting along the side of the bath but it is too wide to fit between the wall and the taps so, for me, that section of grout isn't as well finished.
If this is just for a one off job then it would be possible to cut the spreader in half.
DIY'er so I may be using it wrong
I was looking for some unpowered speakers, which proved harder than I expected, when I found these Phillips SBP1120 speakers. The sound quality is excellent for being powered just by the headphone socket.
No need for batteries or remembering to charge them up.
