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.
