    FLUECO BLITZ R4 is a ready-to-use thixotropic cementitious mortar. Rapid setting, microfibres, medium modulus of elasticity combined with the shrinkage compensation technology turn this mortar into a multipurpose product for repair and levelling of concrete surfaces, which are usually hard to achieve with one product alone. FLUECO BLITZ R4 is suitable for rapid structural repair and smoothing of vertical and horizontal concrete surfaces and reinforced concrete structures. FLUECO BLITZ R4 increases initial and ultimate mechanical strength; it is waterproof, long-lasting – even in aggressive environments – and also ideal for repairing structures exposed to the atmosphere or in contact with water. Applied in layers from 5 to 40 mm thick, FLUECO BLITZ R4 provides strong bonding to steel and concrete and protection against carbonation. FLUECO BLITZ R4 is resistant to chemical and environmental attacks and is suitable for all exposure classes defined by UNI 11104.
