Granite countertop tile: How wide should the grout lines be made?

Question

12x12 tile with tight joints using unsanded grout. How much separation between tiles is needed to hold grout in place and yet look like one solid surface?

Answer 1

Polished grranite or marble "tiles' are usually installed withh NO MORE than 1/16 inch grout lines Especially on counter tops. You should be using an unsanded "wall" grout to grout with.

Happy Tiling and good luck

Answer 2

The very nature of tile doesn't allow it to look like one solid piece. If you what that look get a solid granite countertop.

No more than 1/16" Sanded grout can etch natural stone tiles. Therefore, you use unsanded grout. But unsanded grout can only be used to fill widths 1/16" or less. If the tile has a bevel you can butt the tiles together, but usually, you will find there are tiny size variations, so you won't get them perfectly aligned, leaving a bit of a gap. Therefore, you grout using unsanded grout. That's why I said it won't look like one solid piece.

Good luck

Answer 4

If you have a Home Depot or a Lowes by you they have spacers in all sizes so small spacing that it will almost look solid when finished to as wide as 1inch.. I was grouting like you with tight joints and I spaced it 1/2 inch but I also wanted to see some grout clor also.. Good Luck :)

Answer 5

1/8" is the max. for unsanded grout joints.
if you put them to close the expansion and the contraction of the wood underneath wil cause the edges to chip.
if it a wood subsurface use backerboard under the granite.

you can't make it look like one solid peice because of the way granite is cut the grains in each piece will be differnet and won't match.
good luck.

Answer 6

must be at least 1/8 inch. This will not look like one piece! grout is very porous and will hold dirt and bacteria. seal the grout well with clear sealer to help with cleaning. I have solid granite counter tops and love them. also try to match the color of the grout to the granite so it's less noticeable.

Answer 7

I would personally not do more than an eighth of an inch. Might even want to keep it down to 1/16th of an inch. Best recommendation would be to set up a test. Lightly glue two tiles at a distance and grout them up (alternatively, use a bit of folded paper for visual)

Answer 8

A good deal for the tile but you will need the grout line. Solid surfacing requires full-size sheets.

Answer 9

granite tiles are machined with a micro bevel on the edges so that there is no need to have any space between them. just butt them together and the beveled edges with make a slight groove to fill in with unsanded grout.

Answer 10

Forget the spacers, the old timers use twisted mason's string, believe me it is just the right thickness.
