Remove oil, grease and other contaminants. Work at a surface temperature of 4–32°C. Use Grind Aid+ undiluted for wet grinding only.
Application
Pre-wet the concrete with clean water before applying Grind Aid+. Start with the lowest specified grinding grit and keep the slurry wet throughout grinding.
Spray at low pressure or pour ahead of the grinder and distribute with a soft broom. Allow 8–15 m²/L for the first application and 15–25 m²/L for later applications. Keep the surface wet while grinding; add water if it starts to dry.
Drying and next steps
After each grinding stage, wash with water and collect the slurry with a wet vacuum. Before the final grinding stage, apply C² Hard or C² Hard Blend according to its own instructions.
Clean tools with fresh water before the product dries. Immediately wash splashes off glass, aluminium and other adjacent surfaces.
