A magnesium silicofluoride that reacts chemically with the free lime and calcium salts in hardened concrete to make a more dense and durable surface. It will effectively penetrate a concrete surface and make it hard, free from dusting and highly resistant to corrosion and abrasion. The addition of a patented penetrating agent to SURFHARD makes it possible for its penetrating properties and hardening action to proceed to a greater depth than with conventional hardeners.
