I have used both products-vitremela is a UV cured product. It was hard to work with.
We haven't been able to do a live job with it. Plus the equipment was expensive.
Clear stone is a resin based product that is finished mechanically to a honed or polished finish.
We are currently using this product-we do from 1-3 jobs a month.
It is the only product so far that can give a glass like reflection in a polished finish.
On prior jobs we have gone back to refinish the surface and charge just as if we were finishing their marble.
There is equipment to buy and quite a bit to learn regarding installation
Looks good honed also. It is also quite repairable.
Its under warranty for staining and etching for 10 years.
It will delaminate long before it stains or etches.
It isn't warrantied for scratching and it will scratch.
Folks don't seem to mind the scratching however.
It is a good sell to restaurants,bars, hotels, country clubs-etc.
Its seems to be good for very high end consumers. who aren't concerned about pricing issues.
If $80.00 a sq ft doesn't give them a heart attack or they throw you out the door a potential sale is possible.
Most consumers just cant afford it so you have to know where to market it.
If you market and sell it responsibly you can do ok with it.
We have been working with it for about 2 years now-like everything it has its pros and cons.
Another product that isn't for everyone- on the contractor side as well as the consumer side.
All the tooling and abrasives are compatible with corian jobs as well.
So now we are refinishing corian countertops which is easy and profitable.
