Setting Out How does this modular pattern work? - TilersForums.com

[Rodduz]

On the diagram the width of tiles equates to 2m for both the rows marked 1 & 2.

Row 1 has 6 grout lines
Row 2 has 4

So total width of the rows is different, meaning grout spaces would have to be smaller on the row with more grout lines?

What am I missing?

Thanks

That pattern is self spacing as it works to the tile sizes.

So just pick a grout line size e.g. 3mm and it'll work?

No , the tiles dictate the size , otherwise the pattern wouldn’t tie together if you see what i mean.

So some grout lines will be wider than others?

It is possible with stone tiles but porcelain etc should be equal.

It's blowing my mind, can't get my head round it 🤣

Think I'll dry lay a few and see if it makes more sense

You are absolutely correct about there being extra grout joints in certain lines. That pattern only works exactly when there is no grout joint because the tiles are dimensions of 100 (mm). I'm pretty certain years ago stone tiles were 405x610 etc to accommodate for this. I think competitive stone prices have seen an end to this. With tumbled stone it doesn't matter to much and you tend to end up with varied grout joints, especially with the smaller tiles. I would chalk plenty of lines on the floor to create a grid system and work within those grids. Since your grid repeats perfectly horizontal and vertical this will be easy. Dry lay one pattern to get your measurements. I've only seen porcelain tiles that fit perfect with a 3 mm joint and repeat. They were some very unusual tile sizes to make it work. Hope that helps

Food for thought! Wish I hadn't bothered 🙈

Every time I have to do modular I wish I hadn't bothered.
