This surface preparation system begins with a polymer-modified admixture used as a primer to enhance bonding, improve flexibility, and increase resistance to moisture and chemical attack. Applied over the prepared substrate, it ensures strong adhesion for subsequent layers. Shrinkage free, polymer modified cementitious repair mortar which requires only the addition of clean water to yield a thixotropic mix with good application properties both on vertical, horizontal and overhead surfaces. It can be applied in thickness from 6 mm to 200 mm per layer.
