Applied colours selected from colour charts will be approximate. Colour deviations may occur due to filling with quartz sand. For colour matching: Apply colour sample and confirm selected colour under real lighting conditions. When product is exposed to direct sunlight, there may be some discolouration and colour variation, this has no influence on the function and performance of the floor finish. |

Application Information Mixing Ratio Part A: Part C: Pigment = 12.5 : 25 : 1 parts by weight (pbw) The amount of hardener required to be added to 12,5 kg of Part A: (Sikafloor Pronto Resin) is dependent on the substrate temperature. | Substrate Temperature | Sikafloor Pronto Hardener ( % pbw) | Sikafloor Pronto Filler | Sika Pronto Pigment | | 0 °C | 750 g
(6.0 %) | 25 kg | 1 kg | | +5 °C | 750 g
(6.0 %) | 25 kg | 1 kg | | +10 °C | 500 g
(4.0 %) | 25 kg | 1 kg | | +15 °C | 375 g
(3.0 %) | 25 kg | 1 kg | | +20 °C | 250 g (2.0 %) | 25 kg | 1 kg | | +25 °C | 190 g (1.5 %) | 25 kg | 1 kg | | +30 °C | 125 g (1.0 %) | 25 kg | 1 kg |
The hardener powder can also be ordered under the product name "Perkadox CH 50 X“ or "Perkadox GB-50X" by Akzo Nobel, www.akzonobel.com. Ambient Air Temperature +0 °C min. / +30 °C max. Relative Air Humidity ~80 % max. Dew Point Beware of condensation.
The substrate and uncured applied floor material must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the floor finish. Substrate Temperature +0 °C min. / +30 °C max. Substrate Moisture Content ≤4 % parts by weight The following test methods can be used: Sika-Tramex meter, CM-measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet). Pot Life | Temperature | Time | | 0 °C | ~20 minutes | | +5 °C | ~20 minutes | | +10 °C | ~15 minutes | | +15 °C | ~15 minutes | | +20 °C | ~15 minutes | | +25 °C | ~12 minutes | | +30 °C | ~10 minutes |
