If you were choosing 4x4 or 6x6, I MIGHT be able to see it. But the tile you've chosen comes on sheets of atleast 1 foot square, and the hex very well may be 1 foot by 2 foot. So, no, I disagree with your contractor.

I'll disagree with Bill here. Small mosaic contours to the surface it's being fixed to and requires more prepparation to create a flat surface. Also, I have yet to run into a sheet mosaic that didn't need tweaking to get the sheets to line up correctly. In my professional opinion, there should be an up-charge for the mosaic tile though it shouldn't be extreme.

More grout lines on the smaller tiles, too.

Means nothing. It doesn't take any longer to grout.

Shaughnn, you've seen the job I just did. That was Dal mosaics, and as critical as it was that everything line up, none of the sheets had to get cut and jockeyed around because of mounting. Sometimes, you're right-- the mounting is bad. but if that's the case, then it gets discussed when the tile gets openned up. Not during initial negotiations. As far as prep is concerned, that's also on a job by job basis. Over here in the northeast, 99% of commercial bathrooms use ceramic mosaics , and Other than jobs that were speced for mud, I don't ever remember having to fix a floor that didn't get charged out as an extra, and that's only been a couple of times.

I'm not a pro, just a DIY'er, but my expereince with grouting both has been that it takes longer to grout small tiles than large tiles on the same area, because there are more grout lines.

But then again, I'm not a pro, just a DIY'er.

Bill,
I seem to recall a certain roman tub with Pennyround mosaic that would have been MUCH easier to install if the client had chosen 4x4's instead. I'm just sayin. :^D

Why does it not take longer to grout? We're facing this same issue, potentially. The small hex tiles definitely have more grout lines, but how is grout installed? Do they just spread it over the top, pack it in, and then clean off the top of the tiles? Or is it done individually in each grout line?

It's spread over the top and the excess wiped off.

Thanks for your responses. So it sounds like it could be fair for my GC to charge a small fee increase for labor for installing smaller tiles, but not a huge upcharge.

Why did he say that he will need to take a knife (or something like that) to make every grout line straight? Is there more than one way to do this? From your responses the grout should be simply packed in and wiped off.

He's talking about the same thing Shaughnn was-- cutting up the sheets to straighten them out.

Sorry for bumping an really old thread. But it kind of relates to my thread I just posted. Wondering if the advice is still the same?

Thanks and I apologize again. :)
