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 Sikafloor®-91 mixture while the primer coat is still tacky, and rake out evenly. Level with a beam laid across steel screeding rails and finish with a steel float.
CLEANING OF TOOLS
- Clean all tools and equipment immediately after use with Sika Thinner C (NZ).
- Once hardened, the material can only be removed mechanically.
- Wash soiled hands and skin thoroughly in hot soapy water.
