CEM-OX

Passivating grout for reinforcement irons

Description

CEM-OX is a one component product based on cementitious binders, polymer powders. CEM-OX is specially formulated both as a reinforcing steel corrosion protection and for the construction of adhesion bridges between old concrete parts to be renovated and repair mortars.

Usage field

CEM-OX is used exclusively to treat reinforcement irons that may have been exposed during concrete restoration or following removal of unsteady parts, as well as badly carbonated concrete in need of repair.

Packaging

2 kg plastick buckets.

Application

To ensure that CEM-OX has the possibility of effectively developing its anticorrosive properties, it is essential that the iron, before treatment, is completely freed from rust. Then proceed as described below.

Preparing the Substrate

  • thoroughly clean and remove all loose particles;
  • brush or sandblast the reinforcing steel scheduled for treatment until all traces of rust are removed;
  • wash with water the laying surface.

How to Use

  • Mix 5 kg of CEM-OX with 1÷1.5 liters of clean water and mix slowly with a low rpm U shaped anchor paddle for solids, until a lump-free paste is obtained. CEM-OX should be applied within one hour of preparation.
  • Brush on a first coat of CEM-OX on reinforcing irons taking care to fully coat them with an approx. 1 mm thick product layer.
  • After 1 or more hours, apply a second coat as above mentioned. We recommend to completely and homogeneously cover the surface of the iron. The total thickness of the two coats must be at least 2 mm.
  • Then coat the part to be compensated with GROVE RIPRISTINO within 2-3 hours.
Tool cleaning

Tools and brushes can be cleaned with water if the product is fresh, while if the product has hardened it must be removed mechanically.
