Corrosion Inhibitors - Sika® ferrogard betway sports login®-903
Penetrating, corrosion inhibiting, impregnation coating for hardened betway sports login
Sika® FerroGard®-903 is a corrosion inhibiting impregnation coating for hardened betway sports login surfaces. It is designed to penetrate the surface and then to diffuse in vapor or liquid form to the steel reinforcing bars embedded in the betway sports login . Sika® FerroGard®-903 forms a protective layer on the steel surface which inhibits corrosion caused by the presence of chlorides as well as by carbonation of betway sports login . How it works Sika® FerroGard®-903 is a combination of amino alcohols, and organic and inorganic inhibitors that protects both the anodic and cathodic parts of the corrosion cell. This dual action effect dramatically delays the initiation of corrosion and greatly reduces the overall corrosion activity. Sika Sika® FerroGard®-903 protects the embedded steel by depositing a physical barrier in the form of a protective layer on the surface of the steel reinforcement. This barrier inhibits corrosion of the steel.
Sika® FerroGard®-903 offers owners, specifiers, port authorities, DOTs, and engineers, a new technology in corrosion inhibition that can easily be applied to the surface of existing betway sports login to extend the service life of any reinforced betway sports login structure.
Protects against the harmful effects of corrosion by penetrating the surface of even the most dense betway sports login and diffusing to the steel to inhibit corrosion. Enhances the durability of reinforced betway sports login . Does not require betway sports login removal. Environmentally sound. Does not contain calcium nitrite. Easily applied by either spray or roller to all existing reinforced betway sports login . Can be applied to reinforced betway sports login that already exhibits corrosion. Adds additional benefits when used prior to protective coatings in betway sports login restoration systems. Water based for easy handling and application. Not a vapor barrier; allows vapor diffusion. FerroGard has been proven effective in both laboratory (ASTM G109/Cracked Beams) and field analysis. ANSI/NSF Standard 61 potable water approved Usage
Sika® FerroGard®-903 is recommended for all steel-reinforced, prestressed, precast, post tensioned or marine betway sports login . Use of Sika® FerroGard®-903:
Steel-reinforced betway sports login , bridges and highways exposed to corrosive environments (deicing salts, weathering) Building facades and balconies Steel-reinforced betway sports login in or near a marine environment Parking garages Piers, piles, and betway sports login dock structures As part of Sika’s system approach for buildings and civil engineering structures Advantages

Application
Consumption
Coverage For normal betway sports login , application is 200 ft.2 /gal. each coat. A minimum of two coats is always recommended. For dense betway sports login , application may exceed 300 ft.2/gal. Therefore, more than two coats may be required to achieve the total application rate: 100 ft.2 /gal.
Application Steps
APPLICATION Sika® FerroGard®-903 is applied by roller, brush or spray on betway sports login surfaces. When spraying, use a conventional airless spray system or hand-pressure equipment. A minimum of two coats is always recommended . Dense substrates may require more coats. Waiting time between coats of Sika® FerroGard®-903 is at least 1 hour. Allow a minimum of one day to allow Sika FerroGard 903 to dry and penetrate. When Sika® FerroGard®-903 is used prior to the application of a repair mortar, betway sports login overlay, protective coating, Sikafloor system or any other application, care must be taken to remove any residue remaining on the surface from the application of Sika® FerroGard®-903. Clean the substrate in such a manner (i.e. push the water in one direction away and off from the surface to be overcoated) to completely remove any residue. Horizontal surfaces require pressure washing (2,000 psi minimum) to remove the residue. Vertical surfaces may be rinsed with water or pressure washed. The use of Sika Armatec 110 EpoCem as a bonding agent prior to the application of repair mortars or betway sports login overlays is suggested. Drying times depend on environmental conditions, absorbency of the substrate and maximum recommended moisture content for the subsequently applied system.
