We have had the expensive, Spanish cork flooring for the past 4 years. We had a choice of either tiles covered with a urethane coating or tiles covered with a wax coating. The wax is matte finished and needs to be buffed out to get a glossy shine.
Our cork flooring experience was a fiasco. It was very difficult to find a professional floor laying firm in Seattle that had experience doing jobs for non-commerical, non-office sites. The commercial installation firms wanted to charge an outragious fee, several thousand dollars. The firm we hired, who had an excellent reputation, did a terrible job-so terrible that I ended up not paying them the $1500 bill. After hearing my story, the humbled owner understood and did not seek payment.
Cork floors have rather particular requirements that can be taxing. To do it right requires your room have a special super-strong plywood subfloor to handle the very strong adhesive and possible pulling up of the tiles. It also must be a specific thickness.
The tiles themselves were artier than a bulletin board–for the $2400 cost is better be–and had various dark and light hued patterns on select tiles. The firm which did the job neglected to give any forethought to the layout pattern, even though the strict installation instructions stated so. So when I got home it appeared that a drunk had just clumped a whole mess of dark hued tiles in just a few places on the floor–instead of spreading them out with a design of sorts. The glues used were pretty toxic and my wife was pregnant at the time so she couldn’t really monitor the job.
I called the company to complain and they came back out and had to chisel and rout the ill-placed dark tiles out by hand. Of course the tiles were destroyed and we had to order new ones which had to be shipped from Spain–which took 4 weeks. The contractor paid.
Unfortunately the replacement tiles was imperfectly glued in on two accounts. First, the routing didn’t really remove every bit of the “old” tile, so laying new tile on top of that resulted in a slight lip showing next to adjoining tiles. You don’t really see it, but you do feel it, especially when wearing socks. On top of that, about a dozen tiles (and the room is over 400 square feet) started curling up about an hour after the layer left our home. I ended up putting stack of books on each offending tile and that seems to work fine.
I am sure that I could have called those SOBs back, but I didn’t want to seem them again no matter what the cost. You see, they started this job about three months prior to about when my son was due to be born. I gave them that requirement at the outset. We were planning on having a home birth in the room with the new cork tiles. They messed up big and he was born in another room in the house before they finished the job and we had to seal off the flooring job part of the house to keep the glue smells away from him and my wife. I still resent having to deal with the floor, the hassle, and the bleeping installers instead of helping my wife and being with my son.
After life got stable again I undertook the task of buffing out the wax on the tiles. I rented a commercial waxer and the right pads and all that stuff. I could never get the gloss right and even today they look dull.
There are a few good things to say about the cork–they insulate both sound and cold rather nicely. Dropped glasses don’t break. That’s about it. Aside from our installation horrors, I have been disappointed with the visual aesthetics–too large gaps between tiles really cheapens the whole look.
If you want to consider alternatives check out bamboo. Also we really like linoleum–not the cheesy vinyl stuff that is probably in your home (and most other folks’ too) but the original 1930’s stuff which is made from natural products. There are some great Italian designs available. Both of these floor types are fairly hard, but you can lay nice rugs on top.
