Application
Material temperature
Please refer to the individual Product Data Sheet
Ambient air temperature
+10 °C min. / +30 °C max.
Relative air humidity
80 % r.h. max.
Dew point
Beware of condensation!
The substrate and uncured floor must be at least 3 °C above dew point to reduce the risk of condensation or blooming on the floor finish.
Substrate temperature
+10 °C min. / +30 °C max.
Substrate moisture content
When performing application work with Sikafloor® MultiDur EB-24, the substrate moisture content must not exceed 4% pbw measured by Tramex.
Test method: Sika®-Tramex meter, CM - measurement or Oven-dry-method.
No rising moisture according to ASTM (Polyethylene-sheet).
Use Sikafloor 161 Primer for moisture to 6% pbw
For >6% pbw use Sikafloor EpoCem 81
Waiting time to overcoating
Before applying Sikafloor®-263 SL/-264 on Sikafloor®-161/160 allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 24 hours | 3 days |
| +20 °C | 12 hours | 2 days |
| +30 °C | 8 hours | 1 day |
Before applying Sikafloor®-264 on Sikafloor®-263 SL/-264 allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 30 hours | 48 hours |
| +20 °C | 24 hours | 24 hours |
| +30 °C | 16 hours | 30 hours |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity
For faster intercoat times use Sikafloor Booster - Refer to Sika Techncal Dept. for direction.
Applied product ready for use
| Temperature | Foot traffic | Light traffic | Full cure |
| +10 °C | ~ 72 hours | ~ 6 days | ~ 10 days |
| +20 °C | ~ 24 hours | ~ 4 days | ~ 7 days |

Consumption
Sikafloor® MultiDur EB-24 system (~ 2–4mm)
| Coating System | Product | Consumption |
| Primer | 1 x Sikafloor® 160/-161 | ~ 0.25–0.35 kg/m² |
| Wearing coat | Sikafloor®-263 SL 1 and 2mm Comprising of 1kg of Sikafloor®-264 and 1kg of filler 503 | ~ 1.9kg/m²/mm |
| Broadcast in excess | quartz sand 0.4 – 0.7 mm | ~ 4 kg/m² |
| Top coats | 1–2 × Sikafloor®-264 | ~ 0.25–0.30 kg/m² (4.7-5.5m²/litre) |
SUBSTRATE QUALITY
Substrate should be free of contaminants. Refer to Individual Sikafloor 161/263SL and 264 TDS
25Mpa - Cohesive bond pull off value of >1.5Mpa.
Note: Bond tests should be conducted to confirm the suitability of the substrate.
SUBSTRATE PREPARATION
Surfaces should be clean dry and free of contaminants such as oil grease, curing membranes etc.
Prepared surface should produce a cohesive bond strength value of min.1.5Mpa. and a moisture level of <4%pbw.
All unsound layers of laitance and any existing coatings are to be removed.
Self smoothing layers of Sikafloor® MultiDur EB-24 will not re profile irregularities in the concrete surface.
Profile and defects greater then approx. 1.5 - 2mm will require re-levelling.
This can be achieved using Sikafloor 160/161 mortars and or scratch filling layers.
For applying Sikafloor® MultiDur EB-24 over existing resin finishes, refer to Sika Techncal Dept. for direction
MIXING
Refer to Individual Sikafloor 160 / 263SL and 264 TDS.
APPLICATION
Prime - Sikafloor 160 or 161, work evenly into the substrate at the prescribed rate.
Base Layer - Apply sikafloor 263SL as per the instructions. Take care to apply at the prescribed thickness for an even outcome.
Non slip addition - Introduce broadcast aggregate after approx 10 minutes at 20 degrees. Apply a light even broadacst, then apply the remainder to excess. Care should be taken to throw the broadcast sand high and allow it to fall vertically on the Sikafloor 263SL. Directing the broadcast straight into the product will produce an uneven finish. When hardened, remove the excess broadcast sand thoroughly by brooming and vacuuming.
Finish coats - Apply the first finish coat of Sikafloor 264 by squeegee or roller at the prescribed rate. Work the product into the sand texture.
Apply the final seal coat of Sikafloor 264 at the prescribed rate evely by roller. Cross rolling at 90 degrees is recommended to achieve an even finish.
Note: Apply the two final coats as per the prescribed coverage rates so that the non slip texture profile is correct.
