A concrete densifier is a chemical applied to a concrete surface in order to fill pores, increasing surface density [clarification needed].Chemical densifiers are used on polished and non-polished concrete to reduce dusting and wear; on polished concrete surfaces densifiers help concrete take a better polish and make the surface less permeable to liquids so the slab does not require sealing.
Polished concrete is a multi-step process where a concrete floor is mechanically ground, honed and polished with bonded abrasives in order to cut a concrete floor's surface. It is then refined with each cut in order to achieve a specified level of appearance. This process also includes the use of a penetrant chemical known as a hardener.
