We just completed concrete sealing for this local historic building. The owner wanted nothing changed with the floor, refusing to allow us to grind, hone or polish the concrete. He liked the idea of leaving all of the years of paint, stains and damage in the surface, but wanted a concrete floor that would be more easily maintained in a retail environment. We quickly scrubbed and pressure washed the floor and then applied a high quality solvent acrylic concrete coating. Yes, there are much better products to use, but this is a cost effective product that will fare fine in a residential or light commercial environment – at least with some education. In the end it looks pretty good too!
