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.
When using the resin pads the steps may be 100, then 200, 400, 800, 1600 and finally 3000+ grit. Throughout the process, a densifier is used to harden the concrete surface, which allows the concrete to be polished. A number of densifiers can be used; these consist of lithium, potassium or sodium silicates.
