The usual technique for grounting tiles with radiused edges is well
known, shape the grout with a dowel etc.
However, I had a problem with some cheap tiles where there was no
glaze round the "edge" of the tile. When you radiused the grout in the
usual manner, it exposed the "corner" where the dark biscuit showed
through. A white biscuit would help here, but the issue remains.
Problems were the dark biscuit but also the lack of glaze on the
edges. The usual technique with a dowel recesses the grout a bit,
which also makes wiping off easier without smudging the grout.
I noticed some tiles recently (radiused edge, not square edged
porcelain) in a commercial building, where the grouting was very
shallow. i.e, near the surface of the tile and flat, not radiused like
when you use a dowel.
If I knew how to do that, it would solve the problem with the cheap
tiles I mentioned earlier. I'm not sure how they got the flat shallow
grout lines whilst managing to wipe off the surface sufficiently.
Anyone know the trick ?
