Application
Mixing Ratio
Part A : Part B: Part C: Part D = 100 : 15 : 75 : 22 (by weight)
Product Temperature
+10°C min. / +30°C max.
Ambient Air Temperature
+10°C min. / +30°C max.
Relative Air Humidity
30% min. - 75% max.
During curing the humidity should not exceed 75 % max. Adequate fresh air ventilation must be provided to remove the excess moisture from the curing product.
Dew Point
Beware of condensation!
The substrate and uncured floor must be at least 3°C above the dew point to reduce the risk of condensation or blooming on the floor finish.
Substrate Temperature
+10°C min. / +30°C max.
Waiting Time / Overcoating
| Substrate temperature | Minimum | Maximum |
| +10°C | 30 hours | 2 days |
| +20°C | 24 hours | 1.5 days |
| +30°C | 16 hours | 1 day |
Applied Product Ready for Use
| Temperature | Tack Free | Light traffic | Full cure |
| +10°C | ~ 30 hours | ~ 48 hours | ~ 6 days |
| +20°C | ~ 16 hours | ~ 24 hours | ~ 4 days |
| +30°C | ~ 12 hours | ~ 18 hours | ~ 3 days |
Note: Times are approximate and will be affected by changing ambient conditions.
Consumption
| Coating System | Product | Consumption |
| Sealing of smooth surfaces | Sikafloor®-315 | ~ 0.08 liter (= 0.128 kg) per m2 of DFT of approx. 0.08 mm |
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage etc.
Lower consumption can cause roller marks, gloss differences and irregular surface structure, higher consumption result in water retention.
EQUIPMENT
Sikafloor®-315 must be thoroughly mixed using a electric stirrer or other suitable equipment.
MIXING
Empty completely the Part A, into a clean mixing container large enough to accommodate the whole set, then mix with a Jiffy mix paddle and drill, add the Part B, mix at low speed for approx.1 minute. Then, if pigmented version is required, add the part D, mix for further 2 minutes. Finally, add slowly (don’t dump!) the part C (filler for textured surface) while mixing to avoid clumping, mix for approx. 2 minutes. To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix. Over mixing must be avoided to minimise air entrainment.
Note: Part C must be mixed in Un-Pigmented Set and Pigmented Set. Do not mix more material than can be applied within the working time limits at the actual site temperature
APPLICATION
- Prior to application confirm relative air humidity and dew point.
- The floor should be divided into section sections that can be completed without stopping.
- Section should be divided at expansion joints or doorways when possible. The end of the section should be taped off to form a straight line providing a clean edge for an adjacent section.
- Pour the mixture of Sikafloor®-315 onto the application area, and spread it uniformly with smooth trowel. In order to get better appearance, texture and uniform glossy, the wet film thickness must be controlled in approx. 0.08mm.
- Then immediately back roll the material using short pile roller. The roller should be wet in the roller tray or bucket wet and the excess coating is removed to avoid drips.
- If applied too thick, the material may blister, or have roller marks, if too thin; the coating will appear very flat in sheen.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
CLEANING
- To maintain the appearance of the floor after application, Sikafloor®-315 must have all spillages removed immediately and be regularly cleaned.
- Please refer to the Sika Cleaning Regime.
