- The product is gradually added to the water
- It is mixed with a low-speed mixer
- A homogeneous and lump-free consistency must be achieved
3. Application
- The prepared mortar is applied to the surface with a trowel
- It should be applied in layers of 1 – 1.5 cm thickness
- The surface is leveled with a gauge (screed bar)
4. Smoothing and Finishing (Polishing)
