Application
Mixing Ratio
Part A : Part B = 85 : 15 (by weight)
Layer Thickness
Refer to the System Data Sheets: Sikafloor® MultiDur ES-39, Sikafloor® MultiDur ET-39 V and Sikafloor® MultiDur EB-39
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 | ~60 minutes |
| +20 °C | ~30 minutes |
| +30 °C | ~10 minutes |
Curing Time
Before applying Sikafloor®-390 N on Sikafloor®-390 N allow:
Substrate temperature | Minimum | Maximum |
+10 °C | 48 hours | 3 days |
+20 °C | 30 hours | 2 days |
| +30 °C | 20 hours | 30 hours |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
Consumption
Wall top coat (textured)
~1,2 kg/m² per layer (Includes 2,5–4 % by weight Extender T)
Wearing layer
~1,6 kg/m² / mm
Broadcast layer seal / top coat
~ 0,75-0,85 kg/m² (Includes 5 % by weight Thinner C)
General
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® MultiDur ES-39, Sikafloor® MultiDur ET-39 V and Sikafloor® MultiDur EB-39.
MIXING
Prior to mixing all parts, mix separately Part A (resin) using a low speed single paddle electric stirrer (300–400 rpm). Add Part B (hardener) to Part A and mix part A + B continuously for 3,0 minutes until a uniform mix has been achieved. When Parts A and B have been mixed, if required, gradually add Extender T or Thinner C. Mix for a further 2,0 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 = 3,0 minutes. A+B+Extender T= 5,0 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. If moisture content > 4 % parts by weight, Sikafloor® EpoCem® may be applied as a Temporary Moisture Barrier (T.M.B.) system.
Wall top coat (textured)
The first coat of Sikafloor®-390 N mixed with 2,5- 4 % of Extender T, must be applied by trowel. After waiting the appropriate curing time, apply a second coat of Sikafloor®-390 N, mixed with 2,5- 4 % of Extender T by trowel.
Wearing layer
Pour mixed Sikafloor®-390 N onto prepared substrate and spread evenly using a suitable trowel or pin leveller to the required thickness.
Spike roller immediately in two directions at right angles to each other to remove trowel marks, aid air release, ensure an even thickness and obtain the required surface finish.
Slip resistant broadcast layer
Pour mixed Sikafloor®-390 N onto prepared substrate and spread evenly using a suitable trowel or pin leveller to the required thickness.
Spike roller immediately in two directions at right angles to each other to aid air release and ensure an even thickness. After about 15 minutes (at +20 °C) but before 30 minutes (at +20 °C), broadcast with quartz sand or silicon carbide, at first lightly and then to excess to produce an even distribution surface profile. Allow Sikafloor®-390 N to initially cure and remove all loose sand by vacuum extraction equipment.
Broadcast layer seal / top coat
After waiting the appropriate curing time, pour the mixed Sikafloor®-390 N + 5 % by weight Thinner C 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 and/or cured material can only be removed mechanically.
