Restauro R4 is a ready-to-use, fibre-reinforced mortar for vertical or ceiling application without the need for formwork, slightly expansive both in the plastic and post-hardening phases to counteract the formation of cracks. It is easy to apply either by hand or by spray with a suitable pump, even in layers of several centimetres without any signs of dripping. It guarantees high mechanical characteristics with particular reference to flexural strength, an important parameter for professional repairs of reinforced concrete. Restauro R4 is a product for the structural repair of concrete structures by means of hydraulic mortar of PCC type and class R4 according to EN 1504-3.

Restauro R4 is indicated for:

• Structural plasters;
• Reconstruction of the concrete cover;
• Rebuilding of reinforced concrete elements.

In accordance with EN 1504-9, the fields of application of Restauro R4 referred to in Principle 3 (Concrete Restoration), 4 (Structural Consolidation) and 7 (Preservation or Restoration of Passivity) by means of Methods 3.1, 3.2 and 3.3 (Application of Mortar by Hand), 4.4 (Addition of Mortar or Concrete) and 7.1 and 7.2 (Increase of concrete cover by Addition of Cement Mortar or Concrete).
