The base surface (especially the tile joint) should be clean, dry, free of oil, dust debris residue.

Use                                       Waiting time
Surface drying time               ~3 hours           
Pedestrian traffic                   ~24 hours         
Full traffic                                ~72 hours        
Values determined in laboratory conditions: +23 °C ± 2 °C, R.H. 50 % ± 5 %.
Higher temperatures will reduce the indicated waiting time, lower temperatures increase waiting time.

The consumption is dependent on the size of the tiles, joint width and depth.

Consumption guide: m² / cartridge

These figures are theoretical and do not allow for any additional material
due to surface porosity, surface profile, variations in level or wastage etc.

• The width of the joint should be from 1mm to 5mm to have good decorative effect.
• The surface (especially the tile joint) should be clean, dry, free of oil, dust debris residue.
• Wax the tile surface (especially the gap between tiles) before grouting to make it easier to remove grout residue afterward.
• Open the SikaCeram-855 and load it into the specialized grout gun, making sure both sides are securely locked in place.
• Press the grout gun to release air from both components until they dispense simultaneously. Clean any remaining material, then attach the specialized nozzle.
• Cut the nozzle at a 45-degree angle, ensuring the incision width matches the width of the tile joint.
• Discard the first 30 cm of mixed grout to ensure even mixing and maintain grout  quality. Use well-mixed grout only.
• Apply grout along the tile joints, ensuring an even and uniform fill. Avoid prolonged pauses during application, as this may cause the grout to solidify in the nozzle. Replace the nozzle if necessary before continuing.
• Immediately after applying, use a finishing tool (such as a metal ball) to smooth the grout.
• Immediately clean any spilled grout from the tile surface with a damp cloth or sponge. After 8 hours at room temperature, use a sharp scraper to remove any remaining grout. In winter, allow for a longer cleaning period due to lower temperatures.
• Let the grout cure for 24 hours at temperatures between 20-30°C before handling or allowing foot traffic.
