Application Instructions
- 1
Surface Preparation
The substrate must be sound, clean, and free from dust, oil, and any other contaminants that may reduce adhesion. Voids and damaged areas should be repaired with a suitable repair mortar before application, and the water absorbency of the substrate should be checked.
- 2
Mixing
Pour 6 – 7 L of clean water into a clean mixing container and gradually add the powder mortar. Mix with a low-speed mixer until a homogeneous, lump-free consistency is obtained. Allow the mortar to rest for 5 minutes, then remix before application.

Application
After the primer has been applied and allowed to dry completely, spread the decorative finish coat evenly over the surface using a steel trowel. Depending on the ambient conditions, texture the surface with circular movements using a plastic float after approximately 20 – 30 minutes.
Important Notes
- The application and ambient temperature should be between +5 °C and +35 °C.
- During and after application, protect the surface from direct sunlight, strong winds, excessive moisture, and other adverse environmental conditions.
- The substrate must be free from oil, dust, dirt, and any other contaminants that may reduce adhesion.
- To obtain a homogeneous mortar, mix the product using a low-speed mixer operating at a maximum speed of 120 rpm.
- Do not add lime, sand, cement, or any other additives other than clean water to the mix.
- The prepared mortar should be used within 2 hours. Do not use mortar that has exceeded its pot life or has started to set.
Storage and Shelf Life
Store in the original, unopened packaging in a cool, dry place, protected from moisture, frost, and direct sunlight. When stored under appropriate conditions, the shelf life is 12 months from the date of manufacture.
