FERROSEAL is a ready-to-use cement mortar protecting steel reinforcement elements from corrosion and acting as a bonding layer between the old and new mortar or concrete in repair works. It is classified as a product for reinforcement corrosion protection, according to EN 1504-7. Certificate Nr. 2032-CPR-10.11.
FERROSEAL is used:
- To protect steel reinforcement in repair works to reinforced concrete suffering damages, as a result of an earthquake, carbonation, or defective casting.
- For precentive protection of steel reinforcement in lean building elements or in cases where the structural element is expected to work in wet surroundings.
- As a bonding layer between old and new concrete or mortar.
Substrate preparation
- Reinforcement elements must be free of rust, dust, grease etc.
- Concrete or mortar to be bonded must be free of loose materials, dust, grease etc.
Application
FERROSEAL is added into water under continuous stirring at a ratio of FERROSEAL water = 2.65:1, until a uniform mass is formed with no lumps.
- As an anticorrosive coating, the material is applied with a brush of medium hardeness in two laers. Layer thickness exceeding 1 mm per coat should be avoided because of the risk of crack appearance in the material. Each new layer is applied once the previous one has dried.
- As a bonding layer, between old and new concrete or mortar, the material is applied in one layer approx. 2 mm thick. The new concrete or mortar is applied whilst bonding layer is still fresh.
