The concrete substrate is pretreated by surface grinding, shot blasting or milling. See substrate preparation instructions.
Prime with Nanten Acrylic 101-M1 Primer. Sand (0.6-1.2 mm) is sown on top of the primer to improve adhesion of the grindable render coating 20N-M1.
Main compound is grindable render made with Nanten Acrylic 20N-M1 binder and colored sand, film thickness 3-4 mm. The surface can be roughened by sowing 0.3-0.8 mm of colored sand on the surface of the uncured mass (e.g., commercial kitchens) or a rougher alternative of 0.7-1.2 mm (e.g., loading docks).
Top coat with Nanten Acrylic Sealer 319-M1. Varnishing is done 1-2 times depending on the surface roughness and the desired surface smoothness/structure.
