Consumption
| System | Product | Consumption |
| Primer | Sikafloor®-161 L | 0.35 - 0.55 kg/m² |
| Levelling (optional) | Sikafloor®-161 L leveling mortar | Refer to PDS of Sikafloor®-161 L |
| Self-smoothing wearing course (Film thickness ~ 1.5 - 3.0 mm ) | 1 pbw Sikafloor®-263 SL CN 0.7 pbw quartz sand (Sikadur® 505 Q) | 1.75 kg/m² mixture /mm thickness Filler quantity depended on temperature and filler type |
| Broadcast system (Film thickness ~ 4.0 mm) | 1 pbw Sikafloor®-263 SL CN 1 pbw quartz sand (Sikadur® 505 Q) + broadcasting quartz sand 0.4 -0.7 mm + Seal coat Sikafloor®-263 SL CN | 2.00 kg/m² 2.00 kg/m² ~ 4.0 kg/m² ~ 0.7 kg/m² |
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage etc.
The quantity of quartz sand in self-leveling system based on the temperature of ambient and substrate approx. 23℃ and 2mm thickness. The actual addition of quartz sand should be depending on temperature and thickness on site, higher temperature and thickness, more quantity of quartz sand can be added in to resin mixture.
EQUIPMENT
Sikafloor®-263 SL CN must be mechanically mixed using an electric power stirrer (300 - 400 rpm) or other suitable equipment.
MIXING
Prior to mixing stir part A mechanically. When all of part B has been added to part A, continuously mix for 2 minutes until a uniform mix has been achieved.
When parts A and B have been mixed, the quartz sand 0.1 - 0.3 mm and/or Extender T must be mixed with part A and B for a further 2 minutes until a uniform mix has been achieved.
To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix.
Over mixing must be avoided to minimize air entrainment.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with Thinner C immediately after use. Hardened / cured material can only be mechanically removed.
CLEANING
To maintain the appearance of the floor after application, Sikafloor®-263 SL CN must have all spillages removed immediately and must be regularly cleaned using rotary brush, mechanical scrubbers, scrubber dryer, high pressure washer, wash and vacuum techniques etc. using suitable detergents and waxes.
