Re: Spacer comparisons | | Julia, spacing is dictated generally by the accuracy of the tiles themselves i.e. how square they are and deviation between the tile sizes. Rectified porcelain means it's been graded by the manufacturer and should be very accurate, likewise most soft stones (marble/travertine etc) are very good too.
Tiles that are spot on and a very flat tiling surface allow for very tight grout lines. Trying to use crappy tiles with tight grout lines will lead to stair-stepping at the tile intersections. |
