Consumption
Primer :
Sikafloor® 161 HC | 0.3 – 0.5 kg/m2 |
Screed :
Sikafloor®-161 HC Screed | ~2.0 kg/m2/mm |
Notes : 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
- Stir Component A thoroughly with an electric stirrer prior to batching.
- Add Component B in the correct mix ratio and mix for 2-3 minutes at a low speed.
- Place the correctly batched quantity of Component C in the mixer (forced action type).
- Add the prepared resin mix (Components A + B) while the mixer is running, and continue to mix until a homogeneous and uniformly moist mix is obtained.
APPLICATION
Place the mortar while the primer coat is still tacky, and rake out evenly (Always apply “wet on wet” over Sikafloor®161 HC Primer). Tamp down with a beam laid across steel screeding rails and finish with a steel float.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with thinner C immediately after use.
Hardened/cured material can only be removed mechanically.
