It is specially designed for application after HYDROBLOC 730 surface densifier treatment. It reacts with residual free lime, alkalis and mineral constituents within cementitious substrates to form insoluble mineral compounds, further hardening, stabilizing and densifying the near-surface concrete matrix. It improves abrasion resistance, reduces dusting, enhances surface durability and stabilizes weak or weathered cementitious substrates.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eHYDROBLOC 501 is not a coating and does not form a surface film.
