MARMOCRYL GRANIT is used as the thin finishing coat of rendering works delivering a decorative, colored, water-repellent, rough-textured surface Applicable to all building materials including render, concrete, cement boards, gypsum boards, etc. Suitable for interior and exterior wall surfaces. It replaces the final coat of render. Thanks to its high elasticity and excellent adhesion to the substrate, it is the ideal finish coat for external thermal insulation systems.
Substrate preparation
The substrate must be dry and free of dust, oil or grease. loose materials, etc. It is then primed with FLEX-PRIMER or ML-PRIMER. Smooth or non absorbent surfaces should be primed with PL-BOND. MARMOCRYL GRANIT is applied after the primer has dried.
Application
Before application, MARMOCRYL GRANIT should be stirred with a low-speed mixer in a slow, circular motion to prevent bubble formation in the mass of the material. The render is applied by hand with a smooth, stainless steel trowel or with a rendering machine. While still fresh, MARMOCRYL GRANIT is treated (pressed) with a metal trowel. Working time depends on substrate absorbency and ambient temperature.
