MAPEI PLANITOP REPAIR & SMOOTHING R4: Fiber-Reinforced, High-Performance Concrete Repair and Leveling Mortar
What is PLANITOP REPAIR & SMOOTHING R4?
PLANITOP REPAIR & SMOOTHING R4 is a high-performance R4-class concrete repair and surface leveling mortar that can be applied in thicknesses ranging from 3 mm to 40 mm. Its fiber-reinforced and shrinkage-compensated formulation makes it a reliable solution for both structural repairs and surface correction applications.
With its cement-based composition and compressive strength of ≥45 MPa, it delivers outstanding performance in demanding applications. The ability to apply a wide thickness range in a single layer reduces labor time and provides a practical repair solution.
Thanks to its thixotropic consistency, it does not sag or slump on vertical and overhead surfaces. After curing, it offers excellent adhesion and long-term durability, making it suitable for both interior and exterior applications.
