Pentra-Sil® (HL)


Pentra-Sil® (HL) is a high-solids blended hybrid lithium densifier designed for concrete densifying and hardening in newly placed or existing slabs. Its reactive formulation fills the micro-pores of the concrete, strengthening the surface and prolonging its life. Pentra-Sil® (HL), when used in the polishing process, will deepen clarity and increase reflectivity, while remaining breathable.
