Preparation and working conditions
Surface and air temperature10–32 °C
Finish the required grinding before colouring. Remove dust and residues and allow to dry. Neutralise and rinse any previously acid-stained surface. Confirm colour and absorption on a test area.
Equipment
Use a low-pressure sprayer. Distribute evenly without puddles; avoid forming a fine mist.
Practical advice
Test a representative area with the equipment and preparation planned for the job. Let it dry before assessing the result and coverage.
Use the prepared mixture within 24 hours.
Allow at least 1 hour to dry and keep off the wet floor. Apply a second light coat if needed for colour. Burnish the dry surface with an 800-grit or finer diamond pad to remove excess pigment, then auto-scrub with fresh water, collect and dry. Do not grind after colouring. Apply C² Seal or C² Ultra Seal before putting the floor into service.
Clean tools with fresh water before the product dries. Immediately wash splashes off glass, aluminium and other adjacent surfaces.
