The cured mortar is impermeable to acid gases, waterborne chloride ions and oxygen Resistivity Taywood-Werner 4 Probe - 11,800 Ω cm @ 28 days Clarification of property values: The typical properties given above are derived from laboratory testing. Results derived from field applied samples may vary.
