tile spacer question
When laying the bathroom floor (small) with 6’’ ceramic tile on the diagonal should I use Ό ‘’ or 3/16 ‘’ spacers? Does the larger provide better support/strength?

Either or, I like 3/16 for ceramic, oh and, I never use spacers on floors.:no:

Why not? Don’t you have to have a certain space and amount of grout for strength and stability?

I'm curious too, how come you don't use spacers on floor tile?

And no irlizard, the fractional difference you may end up with by eyeballing will not sacrafice the integrity of the tile. The strenght of the floor comes mostly from the underlayment and subfloor, choosing the right thinset and doing a good job w/ thinset.

I'm with R&D, never used spacers. Too much of the floor tile that I have ever used is no where near the same size and spacers will only cause problems. I have always grided my floors with chalk lines spaced the width of tile plus grout size. Just remember to lay to two lines and the other two will be the grout size distance away.

This crazy question come from lack of experience but whats the point of chalk lines to help keep the tiles in a straight line when you just put thinset down and cant see the floor anymore?

Don't know if this is the answer, but you can see the chalk line if you peanut butter the tiles instead of putting thinset down on the floor, I supposed... for some tiles where you need to see the chalk lines, but for others when you use eyeball, may be you spread on the floor... I would like to see how the expects answer your question too...

HAHA - Peanut butter! that's great. I call it back buttering but I LOVE peanut butter.

Anyway, the chalk guidlines will definitely be visable at least the ones surrounding the section you are worlking on. You don't thinselt the whole floor at once and then tile, rather you work in sections at a time, I think I work in 4x4 or so. So, when you thinset you just don't cover up the border lines around each section, you'll get one tile in say the top left down using both top and side guidlines, then the other tiles will go against the other lines and line up with the top and bottom in every row.

In response to chalking a grid on the floor I then butter the backs of the tile. I got pretty quick with it. It is slower than spacers or freehand but my biggest advantage was the ability to precut all the tile around the walls or cabinets measuring from the lines then when I got to them I would pick one up butter it and stick it. I had no helper and I can't stand getting up and down.


edit: spray your chalk lines with hair spray to keep them from disappearing.

Grids, chaulk lines and lasers.:thumbsup:

KUIPORNG 08-03-2006 09:55 AM

lasers,... an idea I never thought of... I suppose it means put a laser align with the chalkline then, in theory, the "virtual chalkline" is on top of the thinset... what an idea... I would like to try that... I dare not try Big Dave approach, because one mistake in measuring the grid lines could result many pre-cutted tiles too small or too big as the error will be shifted to the edge... this may be either an error on chalk liniing the grids or error on laying the tile, not following the grid... the error will then be popugated... may be OK for professional... but not for one who lays tiles less than 10 times in their life...

Use the spacers
I've probably done quite a few less floors than the other guys that have responded here. But for the average guy doing it for the first time the spacers seemed like a much easier thing that what they are suggesting (no offense). Laying it out with the spacers goes fairly quickly and they don't cost that much in the grand scheme of the work.

I am very inexperienced with tile so I’m gonna cover all bases; story pole chalk lines and spacers. I would probably mortally wound someone if I had a laser:laughing:
