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 ES-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 on Sikafloor®-156/-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 |

| Primer Scratch coat (If required) | 1 × Sikafloor®-160/-161 Sikafloor®-161 filled 1:0.5 filler 503 | ~ 0.25–0.35 kg/m²
1 kg/m² |
| Wearing coat | 1 x Sikafloor®-263 SL 2 and 3mm comprising of 1kg of Sikafloor®-264 and 1kg of filler 503 | ~ 1.9kg/m²/mm |
| Finish coat - optional | Sikafloor 264/-264T AU | ~ 0.20–0.30 kg/m² |
| UV stable Topcoat | Sikafloor 359 AU | 6-8 m²/litre |
Note: For addtional texture, incorporate 60 mesh size alumimium oxide at 5-6% by vol. into finish coat.
SUBSTRATE QUALITY
Substrate be free of contaminants.
Refer to individual Sikafloor 161/263SL and 264T AU TDS.
25Mpa - Cohesive bond pull off value of >1.5 mpa.
Note; Bond tests should be conducted to confirm the suitability of the substrate.
SUBSTRATE PREPARATION
Surfaces should be clean, dry and free of contaminants.
Prepared surface should produce a cohesive bond pull off 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 ES-24 will not re profile irregularities in the concrete surface.
Profile and defects greater than approx.1.5-2mm will require re-levelling.
This can be achieved using Sikafloor 160/161 mortars and or scratch filling layers.
For application of Sikafloor® MultiDur ES-24 over existing resin finishes, refer to Sika Technical Dept. for direction.
