PROPERTIES

Brushable cementitious rust inhibitor for concrete reinforcing steel (rebars). Its powerful corrosion resistant ingredients protect concrete steel reinforcement from rust, caused from the penetration of moisture or water. RUST FREE POWDER waterproofs the reinforcing steel and eliminates any chance of future corrosion. It also works as a substrate coating between new and old concrete due to its exceptional bonding ability. Classified as steel reinforcement corrosion protection product per EN 1504-7.

APPLICATIONS

RUST FREE POWDER is absolutely necessary for the protection of all exposed concrete rebars (pic.4) due to earthquake, carbonation or faulty pouring. It is also recommended as preventive measure for ultra-thin concrete walls, protecting the steel reinforcement in a permanent moisture environment. It is suitable as bonding bridge between old and new concrete.

USE

 
1. Surface preparation
Reinforcing steel (rebars): Clean the reinforcing steel from rust, dust and oils to Sa2 ½ scale, near white blast clean, per DIN 55928-4.
Concrete: Surfaces must be free from loose materials, dirt, oils and they must be thoroughly soaked.

2. Application
Add RUST FREE POWDER in a clean container with cool water, at a mixing ratio of 4 parts RUST FREE POWDER to 1 part water. Mix until a homogeneous mass without lumps is produced, thick enough to stay on an emulsion or regular brush, without dripping.
As a corrosion resistant coat
Apply the product with an emulsion or regular brush in two, 1mm thick coats each. Allow 2-3 hours to pass between coats.
On concrete surface
Apply the same way as described above, after removing all loose materials and soak the surface thoroughly.   
As bonding bridge
Apply a 2mm coat and bond the old with the new concrete or mortar, while the product is still fresh (uncured).



CONSUMPTION

As corrosion protection for reinforcing steel: 70-120gr/m of reinforcing steel.
As bonding bridge coat: 2kg/m2.

As binding coat: 2 kg/m2
