Kerakoll Cementoresina 1 – system component

A Kerakoll Cementoresina 1 is a tinted, two-component resin-based primer smoothing compound for floors. It highlights the structure of the Floorzero stress-distribution layer. The Cementoresina 2 decorative smoothing layer is applied on top, allowing the pattern to show through. This is the Cementoresina system color layer.

• Part of the system: the second layer (color primer) of the Cementoresina 6-layer floor system
• Over Floorzero: highlights the existing structure and fills minor defects
• Colored in the material: can be ordered in the same color code as the Cementoresina 2 layer — so the base layer does not show through the thin topcoat
• Even application: smoothed with Trowel 2 spatula, using small circular motions, 1 mm layer thickness
• Easy to sand: after 5-10 hours waiting, with a 36-grit disc
• Two-component resin: precise mixing required, 30-minute pot life
• 150 Piero Lissoni colors: Color Collection + 10 Warm Collection shades
• Requires Cementoresina 2: not a finished surface on its own

This product is only available as part of the Cementoresina system.
