When it comes to grout thickness you have three major considerations.
Tile with thin grout lines.
Use a grout float with a foam back to avoid scratching the tiles.
Let s talk about grout size options.
When it s exposed to water it will disintegrate and fall out of the crevices between the tiles.
Installing thin grout lines takes much more time because the tile setting has to be far.
Grout size the thickness of the grout is almost as important to the look as the color as it can make the grout stand out or disappear almost completely if you choose a wider or.
Minimum grout lines the quick answer is nothing closer than 1 16.
Non rectified tiles can t get as close together as rectified tiles meaning there is a limit to how thin your grout lines can be which brings me to my next point.
Spread the grout across the tile while it s still wet.

The smaller the tile the smaller the.
Force the grout into the grout lines.
I separate most tiles into three different categories.
Grout is a necessary and integral part of many tile jobs for several reasons.
Thin grout can also shrink more than it s supposed to which can lead to cracking.
Scoop up grout from the bucket and smear it onto the edge of a grout float.
A small grout line width about 1 16 inch is possible if the flooring tile is consistent in size.
Note that using the smallest grout possible will increase installation time.
Finished grout lines will vary from 1 16 to 3 16.
Grout that is too thick won t fully seal the tile because it ll be too thick to reach the bottom of the cracks.
Choosing a grout width small grout joints.
Tiles that vary in.
Grout should typically remain proportionate with tiles.
Small format tile tiles up to and including 8 x 8 inches square.
Actual finished grout spaces will vary from 1 8 to 1 4 if 3 16 spacers are used.
If smaller spacers like 1 8 are used it will accentuate the size difference of handmade tile.
When re modeling floors bathroom or a kitchen almost everybody wants to have the minimum grout lines between their tiles.
Regular 12 x 12 up to 16 x 16 inches square.
And the bevel on the tile can impact how big the grout lines are because even if the tiles are 1 16 apart the bevel on the tile limits how far down into the crack the grout float can go to scrape out the excess grout.
Large format tile 18 x 18 inches and larger.
Drag the edge of the grout float across the tiles forcing the grout into the grout lines.
It keeps moisture out of the substrate helps keep tile lines straight and prevents tiles from rubbing against one.
