Silanes - Sika® FerroGard®-908
Dual functional surface applied corrosion inhibitor and penetrating sealer for reinforced concrete
Sika® FerroGard®-908 is designed to be applied to the concrete surface. Sika® FerroGard®-908 penetrates the concrete and mitigates active corrosion and/or delays the onset of corrosion.
- Passes - USBR M-82 Corrosion Mitigation Test Protocol
- Significantly reduces active corrosion due to chlorides and or carbonation,even in cracked concrete
- Increases the resistivity of the reinforced concrete
- Enhances the durability of reinforced concrete
- Long term efficiency, deep penetration
- Does not require concrete removal
- Repels additional water and chloride ions
- Contains amino alcohol corrosion inhibitor
- Ready to use and easily applied by spray or roller
- Adds additional benefits when used prior to protective coatings in concrete restoration systems
- Not a vapor barrier; allows vapor diffusion
- Proven effective per ASTM G109/Cracked Beams
- Increases the resistance of concrete to freeze and thaw cycles and de-icing salts
Usage
Sika® FerroGard®-908 is recommended for steel-reinforced concrete, pre-stressed, precast, post tensioned concrete or concrete in marine environments. Common applications include:
- Bridges and highways exposed to corrosive environments (deicing salts, weathering)
- Building facades and balconies
- Parking garages
- Piers, piles, and concrete dock structures
- Vertical, horizontal and overhead surfaces
- As part of Sika’s system approach for buildings and civil engineering

Ambient Air Temperature40-95 °F
Consumption
CoverageRequired consumption is 125 sf / gallon. This is normally achieved with 2 coats (250 sf/gallon/coat); however 3 coats may be required for dense concrete and 1 coat may be achievable on porous concrete. Site mockups should be completed to verify.
Application Steps
APPLICATIONApply using a low-pressure spray, brush or roller, in a single pass from the bottom up taking care not to let the product run. Apply subsequent coats wet on wet. Avoid ponding on the surface.
If used as a corrosion treatment prior to the application of Sikagard® and Sikalastic® protective coatings.
To ensure excellent bond, use of Sika® Concrete Repair Systems, sealants and coatings is strongly encouraged. Field mock ups are always recommended to verify final construction installation requirements.
Do not apply Sika® FerroGard®-908 to wet or damp substrates. Do not apply if rain is expected within four hours following application, or if high winds or other conditions prevent proper application.
