There are epoxy concrete sealers, but not all of them are....lots of times sealers are used to give a "slick" finish to the concrete's surface, and it can also prevent water from absorbing into the concrete, and make cleaning the floor, even running a dust mop over top of it, much easier.
The problem lies in the types of sealers.... a transparent sealer is used where the beauty of the concrete is to be emphasized, such as exposed aggregate. If you want the sealer itself to be the finish, then there are epoxy coatings that will both seal, and cover the concrete.
Most times, once a transparent sealer is used, very little else will adhere to it....and it can be quite slippery, especially when wet.
Talk to your finisher, and tell him/her what you want.... they can recommend a product that will do exactly what you expect.
