We placed the upper floor concrete a few weeks ago which will serve as the finished floor for the Kitchen, Dining Room, and Living Room. The floor was lined with tubing for radiant heating AND cooling through-out the floor. The concrete contained integral color. It was supposed to be ‘charcoal’, but turned out to be more of an ‘eggplant’. At first this was a concern, but the color has grown on us, and as luck would have it is going to be an even better color for the space. Whew!
