Application
Mixing Ratio
Part A : Part B = 82 : 18 (by weight)
Ambient Air Temperature
+10 °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.
Low temperatures and high humidity conditions increase the probability of blooming.
Substrate Temperature
+10 °C min. / +30 °C max.
Substrate Moisture Content
≤ 4 % parts by weight
Test method: Sika®-Tramex meter, CM-measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).
Pot Life
| Temperature | Time |
| +10 °C | ~50 minutes |
| +20 °C | ~25 minutes |
| +30 °C | ~15 minutes |
Curing Time
Before applying Sikafloor®-378 on Sikafloor®-378 allow:
Substrate temperature | Minimum | Maximum |
+10 °C | 30 hours | 3 days |
+20 °C | 24 hours | 2 days |
| +30 °C | 16 hours | 1 days |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
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 |
| +30 °C | ~18 hours | ~2 days | ~5 days |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
Consumption
~0.7–0.9 kg/m² applied as a roller coating
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc. For detailed information, refer to the System Data Sheets: Sikafloor® Multiflex PB-21, Sikafloor® Multiflex PB-52.
MIXING
Prior to mixing all parts, mix separately Part A (resin) using a low speed single paddle electric stirrer (300–400 rpm) other suitable equipment. Mix liquid and all the coloured pigment until a uniform colour has been achieved. Add Part B (hardener) to Part A and mix Part A + B continuously for 3 minutes until a uniformly coloured mix has been achieved then, if required, gradually add the appropriate amount of Sika® Extender T. Mix for a further 2 minutes until a uniform mix has been achieved. To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth consistent mix. Excessive mixing must be avoided to minimise air entrainment. During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing. Mix full units only. Mixing time for A + B + Sika® Extender T (if required) = 5 minutes.
APPLICATION
Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.
Prior to application, confirm substrate moisture content, relative air humidity, dew point, substrate, air and product temperatures.
Seal coat
After waiting the appropriate overcoating time / curing, pour the mixed material onto the slip resistant broadcast layer and spread evenly using a squeegee at the required consumption rate to completely encapsulate the sand. Then using a short-piled roller, back roller in two directions at right angles to each other. A seamless finish can be achieved if a ‘wet’ edge is maintained during application.
CLEANING OF TOOLS
Clean all tools and application equipment with Thinner C immediately after use. Hardened material can only be removed mechanically.
CLEANING
To maintain the appearance of the floor after application, Sikafloor®-378 must have all spillages removed immediately and must be regularly cleaned using rotary brush, mechanical scrubbers, scrubber dryer, high pressure washer, wash and vacuum techniques etc. using suitable detergents and waxes. Refer to Sika Method Statement: Sikafloor®-Cleaning Regime.
