Ruregold MX -R4 Repair Plaster
MX -R4 REPAIR PLASTER
MX -R4 REPAIR PLASTER
Fiber-reinforced thixotropic shrinkage- compensated mortar for applications on concrete
MX-R4 Repair is a premix based on cement, select aggregates, super-fluidifying additives, shrinkage control agents for both the plastic phase (UNI 8996) and the hardened phase (UNI 8147), and polypropylene fibers.
After the addition of water, a thixotropic mortar is obtained, highly adhesive to concrete, brick and iron, durable, and suitable for repairs and structural coverings, without shrinkage. It is ready to use: just add water to obtain a thixotropic mixture with no bleeding or segregation phenomena.It can be applied by trowel or spray. For a surface finish that ensures a high aesthetic quality of the intervention, use a suitable finishing coat.
