I want to lay concrete floors in my home. To include kitchen, living room and hallway. Anyone have experience with this ? I thought wood at first ... but there is just something classy about concrete. I heard $3 - $8 dollars. Figure area rugs would draw everything together nicely. Wood is not off the table at this point. How long does it last ? How periodically would you need to reseal it ? concrete vs hardwood - pro's / cons ?
