MUI HI-PROGUARD CHLORIDE ABSORBER AND PROTECTING COATING FOR CONCRETE STRUCTURES HI-PROGUARD is the longest proven track record coating for concrete structures to protect from corrosion, chemical attacks and carbonation in sever environments. Hi-Proguard provides the highest level of protection by special formulated pre-mixed powder polymer mortar containing super fine blast furnace slag. Coating Applications Coastal and marine structures subject to chloride corrosion. Sewage treatment plants. Tunnel concrete walls to prevent carbonation. Dams, retaining walls, river embankment, and road subject to frost damages. All concrete structures requiring an addition durability. Characteristics More durable than any other types of coating including mortar and epoxy coating. Highest level of protection for chloride corrosion. High resistance to chemical attacks. High resistance to water permeation (< 1.2%). Best protection for freeze-thaw damages Carbonation control capability. Environmental safe because of no VOC,. Easy preparation add water Easy application due to the low viscosity. Add water and apply by spraying, brushing or rollers. 20 kg bag covers 6 m2 of concrete surface at 2 mm thickness.
