POLYBIT Polycrete ST
Polymer modified high strength cementitious repair mortar

Polycrete ST can be mixed by mechanical means. Slowly add the Polycrete ST to 3.50-4.0L 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 by 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 polyethylene sheet which shall be taped to all edges.
