We're adding a outdoor balcony, veranda, and pool deck and want to
cover it in 18 inch sqare travertine. We've found a Turkish stone that
is lightly tumbled (edges rough, partly unfilled but partly smooth).
It has the colors we like and is at a price we can afford ($5.25 per
square foot).
Travertine is beautiful, long lasting, and it gives the kind of Italian
look we want, but

1. I'm concerned about it becoming slippery when wet. Is that going
to be a problem?
Is this related to the sealant? What can I do, if I use this, to make
it less slippery.

2. the unfilled holes: are these going to be a problem? I don't expect
or even want a perfectly clean smooth tile surface outside, so that
doesn't bother me. But are there other problems I should be concerned
about.

I live in Columbia SC so the weather is generally warm with very
infrequent freezes. I'm told the light travertine stone is relatively
cool on the feet in the hot sun.

thanks
