If this is raw concrete, you have several options, however is any case make sure that your installer adds "shark grip" so you do not have a skating rink when it is wet.
If you already have a coating then you need to proceed more carefully, as some coatings may not be compatible with what is already on the concrete. This may require grinding (or something similar) to remove the existing coating so you have fresh concrete to work with.
We had driveways by Jay do our birdcage and the Lanai which had a prior coating on it, about 1 year ago, so far so good.
