Application
Mixing Ratio
The amount of Hardener required is dependent on the ambient- and substrate temperature (see table below).
Sikafloor-13 Pronto: 12.5 kg
Sika-Pronto Hardener (%pbw):
-10°C | 875 g | 7,0 % |
0°C | 625 g | 5,0 % |
+10°C | 500 g | 4,0 % |
| +20°C | 375 g | 3,0 % |
| +30°C | 250 g | 2,0 % |
The hardener powder can also be ordered under the product name „Perkadox CH 50 X“ by Akzo Nobel, www.akzonobel.com or “Interox BP-50 FT” by Degussa, www.degussa.com or “BP 50 W+” by Pergan GmbH, www.pergan.com.
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.
Pot Life
| Time (minutes) | |
| -10°C | ~ 22 |
| 0°C | ~ 15 |
| 10°C | ~ 13 |
| 20°C | ~ 12 |
| 30°C | ~ 10 |
Times are approximate and will be affected by changing ambient condition.
Curing Time
Before applying Sikafloor-13 Pronto / -14 / -15 Pronto on Sikafloor-13 Pronto allow:
| Substrate temperature | Minimum (minutes) | Maximum (hours) |
-10°C | 70 | * |
0°C | 50 | * |
| +10°C | 45 | * |
| +20°C | 40 | * |
| +30°C | 35 | * |
*No time limit, the Sikafloor-Pronto materials can be applied on each other after thorough cleaning
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
Applied Product Ready for Use
Foot traffic (minutes) | Full cure (hours) | |
| -10°C | 70 | ~ 2 |
| 0°C | 50 | ~ 2 |
| 10°C | 45 | ~ 2 |
20°C | 40 | ~ 2 |
30°C | 35 | ~ 2 |
Times are approximate and will be affected by changing ambient conditions.
Consumption
Coating System | Product | Consumption |
Primer | 1-2 x Sikafloor-13 Pronto | 1-2 x 0.40 - 0.50 kg/m² per coat |
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile ,variations in level or wastage etc.
MIXING
Mix part A thoroughly, then add the Hardener in the correct quantity and mix for a further 1 minute.
Over mixing must be avoided to minimise air entrainment.
For ease of handling, 25 kg units may be split (2 x 12.5 kg) (refer to Mixing table). Always weigh out components.
For indoor work, spark-free mixing equipment must be used (explosion-proof)!
Sikafloor-13 Pronto must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.
APPLICATION
Prior to application, confirm substrate moisture content, r.h. and dew point.
For external applications, apply on a falling temperature. If applied during rising temperatures “pin holing” may occur from rising air.
Priming:
Normal non-porous surfaces:
Apply one coat of Sikafloor-13 Pronto. Make sure that a continuous, pore free coat covers the substrate, i.e. minimum 0.4 kg/mm². If in doubt, apply another priming coat.
Absorbent surfaces:
Apply two coats wet on wet of Sikafloor-13 Pronto until saturation of the substrate is achieved. For waiting time before overcoating see table “Waiting Time / Overcoatability”. Apply Sikafloor-13 Pronto using a “non-fuzzing”, short-pile nylon roller.
The freshly applied priming coat can be blinded lightly with quartz sand
0.7 - 1.2 mm, consumption approx. 0.2 - 0.5 kg/m². If the subsequent layer is Sikafloor-15 Pronto, lightly blinding is mandatory.
CLEANING OF EQUIPMENT
Clean all tools with Sika Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
