MX-R4 Repair

Fibre reinforced thixotropic R4 class mortar with compensated shrinkage for application on concrete.

System description

Fibre reinforced thixotropic R4 class mortar with compensated shrinkage for application on concrete.

MX-R4 Repair is a premix based on cement, selected aggregates, super plasticiser admixtures and polypropylene fibres with shrinkage control agents in both the plastic phase (UNI 8996) and the hardened phase (UNI 8147). Adding water produces a thixotropic mortar that is highly adhesive to concrete, brick and steel, it is durable and suitable for structural repairs and coatings, without shrinkage.

Ideal for preparing and reparing the existing concrete and masonry substrate for the application of FRCM, FRP and Reinforced Plaster structural strengthening systems.

Ready to use: just add water for a thixotropic paste that can be applied by trowel or spray.
For surface finishes that guarantee high aesthetic quality, use a suitable skim coat.
