Polymer modified high strength cementitious repair mortar

 Polycrete ST is a high strength structural polymer modified repair mortar. The product is specially formulated by blending opc with non shrinking additives, fibres, polymers and fillers for repairing of beams, columns and Slabs in structures which are subjected to dynamic loads and traffic.


  • Extra reinforced strength due to the presence of fibres
  • Shrinkage compensated
  • Suitable for high build applications
  • Suitable for use in marine and industrial areas
  • Prevents the corrosion of steel reinforcement in concrete
  • Can be applied by trowel, pump or spray
  • High strength repair of concrete


The surface of the concrete to be repaired should be sound, clean and uncontaminated. The decayed or damaged area should be saw cut, keeping the sides of the area as square as possible. Loose materials must be removed carefully using suitable means such as sharp tools or chipping hammer. If the reinforcement is corroded make sure that the back of the steel is completely exposed. Then clean the steel to bright metal condition.


Reinforcement steel: after cleaning, prime the reinforcement using zinc rich primer (Polyzinc*).  Brush apply a continuous coat of Polyzinc to the dry steel. A second coat may be applied after 1-2 hours to cover all the pin holes.

Concrete: if the concrete damage is severe and is due to chloride attack, a bonding coat with Polybond EP*/Polybond AC* is advisable before placing Polycrete ST to achieve optimum bond in the fresh and cured sections. To achieve optimum bond between fresh and cured section, Polycrete ST should be applied when the bonding coat is still tacky. For new concrete saturate the area to be repaired thoroughly with water prior to the application of the repair mortar.


Polycrete ST can be mixed by mechanical means. Slowly add the Polycrete ST to 3.50-4.0 ltr. of clean gauged water (w/p ratio of 0.14 - 0.16 approx) working well to produce a smooth mortar. the consistency of the mix can be adjusted by the addition of more powder or water as necessary, depending on the temperature.


Whilst the primer is still tacky, apply the mortar mix and compact well. application can be done with trowel or a rubber hand glove to paste the material in place. Polycrete ST can be applied to desired thicknesses in layers on vertical and overhead surfaces. high build application can be achieved by using a formwork. while applying multiple layers, the previous layer should be crosshatched and allowed to set before applying the next coat. Polycrete ST can be applied to a thickness of 40 mm in one single application if the ambient temperature is less than 25°C and the weather conditions are normal.


Due to the presence of rapid drying polymers, the repaired area shall be cured in accordance with good concrete curing practice and protected from drying winds. Curing shall be done by non degradable type of curing compounds or wet hessian cloth. when cured with wet hessian cloth, the area shall be covered immediately with a high density polyethyelene sheet which shall be taped to all edges.
