I'm going to put some sealant between the kitchen worktop and wall-tiles.
I've got a 'smoothing tool' (no wisecracks please) which has both straight and curved profiles. You can get a straight-edged (45 degrees) profile or a curved (concave) one (like you'd get with a lolly-stick).
Has anyone any views on which profile shape is is best - straight or concave? Or doesn't it matter?
Cheers
