Ameripolish® 2D PL is a multi-silicate blend, that is intended for use on extremley porous concrete. 2D PL sets up faster than other Ameripolish® densifiers, this keeps the majority of the 2D PL at the surface of the concrete in order to harden the wearable surface. Its ideal use is on open or porous concrete that will readily accept densifiers. When used in conjunction with Ameripolish® SR² Stain Resistor it is especially effective at resisting stains.
