Rust Blocker Powder
Cementitious slurry mortar for reinforcement anti-corrosion protection - Bonding bridge
Rust Blocker Powder is applied as a corrosion inhibitor for the protection of steel reinforcement in repaired reinforced concrete that has been damaged due to mechanical (vibrations, impacts), chemical, or physical (adverse weather/environmental conditions) stresses.
It is also used preventively as a corrosion inhibitor, particularly for protecting steel reinforcement in cases of thin concrete or environments with high humidity.
In addition, it acts as a bonding bridge, ensuring seamless adhesion between old concrete and new concrete/repairing mortar.
Advantages
- Excellent anti-corrosion protection
- Improves the adhesion of the new concrete
- Easy and quick protection
- Mixing only with water
- High protection against corrosive agents
- Enhances the mechanical strength of reinforcement steel

General Information
Rust Blocker Powder is a cementitious slurry mortar for reinforcement anti-corrosion protection which can act as a bonding bridge between the old and new concrete. It contains natural hydraulic recycled binders (Recycled Green Technology)specialized polymers, active micro-additives, and a corrosion inhibitor which, when mixed and applied to the surface of the steel reinforcement, form a protective coating that prevents the penetration of any corrosive agent (moisture, chlorides, etc.), while simultaneously enhancing the mechanical properties of the reinforcement — suitable for both above-ground and below-ground applications. Its final surface also acts as a bonding bridge, as it creates the ideal substrate for the new concrete/repairing mortar to adhere and integrate seamlessly.
How to Use
Reinforcement steel
The reinforcement must be completely free of rust, mortar, concrete residues, dust or any other material that may reduce the adhesion or promote further corrosion. Sandblasting or hydroblasting is recommended and when that is not possible, use alternatively a metallic brush for thoroughly cleaning.
Deteriorated Concrete
The concrete surface must be free from dust, loosely adhered particles, oils, grease, or other contaminants. Areas of deteriorated concrete (delaminated, cracked, etc.) must be removed using mechanical means. The surface should then be pre-wetted to saturation, ensuring that no standing water remains.
As a Corrosion Inhibitor:
Apply the first coat (approx. 1 mm thick) to the clean reinforcement steel using a brush or medium-hard bristle paintbrush. After the first coat has dried (approx. 2–4 hours), apply a second coat of the same thickness, ensuring full and uniform coverage of the steel surface without gaps. Wait at least 6 hours after the second coat before applying any repair mortar or new concrete.
As a Bonding Bridge:
Apply a 2 mm thick coat of the material to the pre-wetted surface of the old concrete using a brush or paintbrush. While the product is still fresh, apply the new concrete or repair mortar.
- Clean tools immediately after use with plenty of water while the material is still fresh.
- Once hardened, remove residues mechanically.
- Store in a dry environment, protected from moisture, in its original sealed packaging, preferably on shelves.The product remains stable for 12 months from the production date under proper storage conditions.
