Hi There, not all the Caesarstone tops leave finger marks I have the Raw Concrete in my kitchen and yes we do need to clean it but its a really nice look in a matte finish and we are happy with it, I have had many years experience with stone benchtops and silestone is OK but it can differ from the sample a little as they source the materials from multi-able countries which can create variations to the sample, Caesarstone is more on point when matching the colour sample and this would explain the extra cost in the product. In short id suggest like I do with all my clients go to a show room where you can see the stone in large samples to best gauge the look and feel of the products looking at 100mm x 100mm samples does not cut it when spending the amount you do for stone. good luck with your search. http://www.caesarstone.com.au/find-a-display https://www.silestoneoceania.com/where-to-buy/

Both sounds good to me. I am a fan of colour though, so its a biased answer from me.

I've used them in commercial buildings , but to keep warm or cooled air in -- I don't know if they are a barrier for bugs ?

I'm interested in what (dulux) colour cabinetry looks good with this type of porcelain benchtop for a kitchen.
