We're extending our house and will have exposed concrete floors in the north-facing living areas. We plan on putting some colour in the concrete mix and simply getting a steel-trowel finish. I'm currently looking into concrete finishing products - polyurethane or natural oil - which we will be applying ourselves.
I'd love to hear of experiences people have had with different finishes, particularly low- or no-VOC products. How difficult/easy was application? How hard wearing are different finishes? And it would be great if anyone has any photos they could share.
