Is the top of this flooring smooth? We are using for a home gym, but my daughter will also practice her ballet on it, so she needs to be able to spin.

Our 1/2" Mega Rubber Rolls are smooth on the top and bottom of the rolls. Our rubber flooring is not the proper floor for practicing ballet. For ballet, you will need a certain amount of slip, and rubber flooring is known as one of the best non-slip floors on the market. If you wanted a great multiuse floor that is great for working out on and for ballet, we recommend purchasing our Impact Rolls - Wood Series. This floor combines the properties of a rubber floor with a vinyl top that will allow for the proper amount of slip needed for practicing ballet.
