For a concrete floor, do you recommend using a concrete densifier (between grinding and polishing phases) before applying this sealer?

GBS Penetrating Concrete Sealer is designed for porous concrete that is clean, dry and neutral pH. Porosity can be accomplished either mechanically through grinding or chemically with an etching product (GBS MicroEtch). Polishing or densifying will create a less porous surface and make it much harder, if not impossible, for our sealer to penetrate.
