How to Fix Concrete Floors

'Acceptable' Number of Cracks in Concrete Floor

What is an acceptable quantity of cracks, and should pieces of the floor come out? Is there any way to halt the seemingly never-ending growth of the cracks? What can we use to fill the cracks to minimize the dark moisture staining that is taking place along the surfaces adjacent to the cracks?

Terrazzo Concrete Floor Control Joints

Does the concrete slab for a terrazzo floor require control joints? Typically we pour a monolithic concrete floor, but then we get minor alligator cracking. We usually cover this with a bridging membrane and finish material.

Tape Marks on Concrete Floors

About two months after the floor was installed, we had the interior of the house painted, and the painting contractor covered the concrete floor with sheets of paper, using painter's tape to hold them in place. When he pulled up the tape a week later, after he finished his painting, it took off the top surface of the concrete down to sand and stone.
