RG 15 is used as rough cast for interior and exterior surfaces like brick, block, etc. before the application of lime-based plasters and hydraulic binder. It is used in restoration work to homogenize the areas to be subsequently plastered with plasters like our own FG 12, IG 14, and so on. The application must be performed on surfaces free of dust, efflorescence, oils, fats.
RG 15 should not be applied to gypsum, inconsistent and brittle surfaces and on concrete surfaces, where we recommend the use of our RG 12.
The application must be made in a completely covering manner.
