Where is G·SAVE used?
Used for localized repairs to cut edges, welds and transport damage on hot-dip galvanized, electrogalvanized and POSMAC structures.
Lamellar barrier protection and zinc sacrificial-anode action
Overlapping zinc flakes form a barrier against corrosive agents. At exposed areas, zinc oxidizes preferentially to help protect the steel substrate.
Barrier Protection
Overlapping zinc flakes provide a physical barrier against moisture, salt and other corrosive agents.
Sacrificial Protection
At coating defects where steel is exposed, zinc corrodes preferentially to provide electrochemical protection.
15–20 µm Thin-film Application
A thin protective film can reduce material use and application time.
On-site Application
Room-temperature-drying spray for installed structures, with a stated drying time of up to 15 minutes under the specified application conditions.
Corrosion resistance and coating-property test results
In the referenced salt spray comparisons, G·SAVE-treated specimens outperformed the corresponding galvanized-only specimens. KTR test results are available for adhesion, pencil hardness and neutral salt spray performance.
| Specimen System | Test Method | Result |
|---|---|---|
| Hot-dip galvanizing 80 µm, without repair coating | KS D 9502 (5% NaCl·35℃) | White rust across the surface at 120 hr; red rust at 480 hr |
| Hot-dip galvanizing + G·SAVE 20 µm | KS D 9502 (5% NaCl·35℃) | No abnormalities at 480 hr |
| Hot-dip galvanizing 80 µm after welding (flange/pipe weld area) | KS D 9502 | White and black corrosion products from 120 hr; red rust at 400 hr |
| Ceramic Galvanizing 15 µm + G·SAVE/Innotouch touch-up 12 µm after welding | KS D 9502 | No abnormalities through 500 hr; minor red rust at 650 hr |
| Welded specimen + G·SAVE | ASTM B117 | No red rust at 240 hr |
Grade 0

Grade 0 in a 1 mm cross-cut test to KS M ISO 2409:2013; specimen from the guardrail-restoration development program.
8H
Pencil Hardness (KTR)
KS M ISO 15184:2012; specimen from the guardrail-restoration development program.
SST
Neutral Salt Spray (KTR)
Comparative test results against conventional hot-dip galvanizing are available under KS D 9502:2020.
Comparison data is reproduced from the product catalog; KTR results are from accredited laboratory testing. Weld-area applications include hot-dip galvanized, electrogalvanized and POSMAC substrates.
Restoration targets above the referenced installation criteria
KEMP sets its own restoration quality targets above the referenced guardrail criteria in the Korea Expressway Corporation's 2021 construction-material quality requirements (20th edition): 480 hr salt spray and 20 cyclic-corrosion cycles for new installations.
720hr+
Salt Spray Test
Target: at least 720 hr to KS D 9502, compared with the referenced 480 hr criterion for new installations.
30cy+
Cyclic Corrosion
Target: at least 30 cycles to KS ISO 14993 / JIS H 8502, compared with the referenced 20-cycle criterion for new installations.
20㎛
Coating Thickness
Coating thickness target: 20 µm, measured to ASTM B499.
These are KEMP's own restoration quality targets, not a statement that every application has achieved them.
Corrosion assessment, localized repair, protection restoration and maintenance
The G·SAVE on-site restoration process comprises corrosion assessment, repair-area definition, surface preparation, protective repair coating and maintenance. Sound areas of existing guardrails are retained while damaged areas receive localized repair, supporting continued service.
01
Corrosion-condition assessment
Assess the structure's corrosion condition and define the repair area.
02
Surface preparation and localized repair
After rust removal and ROC.3 pretreatment, apply G·SAVE to the corroded or damaged areas.
03
Surface restoration of existing components
Restore suitable existing structures instead of replacing them, reducing material waste.
04
Maintenance of restored areas
Inspect and maintain the structure against the agreed restoration quality criteria.
Corrosion-protection repair of structures, cut edges and welds
On-site Guardrail Restoration
Restores suitable corroded guardrails on site without replacement.
Corroded Areas, Cut Edges and Welds
Repairs damaged areas of galvanized and steel structures to help restore corrosion protection.
On-site protective coating of bare steel
Forms a zinc-containing protective coating on suitable uncoated steel through on-site application.
Maintenance of Installed Structures
Helps control corrosion progression and maintain existing steel structures.
Substance test results and integrated repair processes
The formulation does not use xylene, toluene or ethylbenzene. Available documentation includes Korean consumer chemical product safety results covering 7 non-detected substances, including formaldehyde, acetaldehyde and benzene, and a separate report covering 26 non-detected substance test items.

ROC.3 — Pretreatment
A citric- and phosphoric-acid-based rust and oil remover prepares the surface before repair.
Innotouch — Appearance Touch-up
Adds a bright metallic-silver touch-up after G·SAVE repair to restore appearance and supplement protection.
G+PLUS — Clear Finish
Adds a clear inorganic-binder finish for final protection of the repaired area.
Three-product spray sequence: G·SAVE → Innotouch → G+PLUS.
G·SAVE: Key Questions
Key considerations when selecting a repair system for damaged galvanized surfaces and weld areas.
How does it differ from ordinary silver paint?
It combines zinc flakes with an inorganic binder to support restoration of corrosion protection, rather than appearance correction alone.
What should be checked before on-site application?
Check rust and contamination removal, damage extent, required coating thickness, drying time and the exposure environment.
