Application Method
Surface Preparation
The substrate must be free from dust, oil, paint, and loose particles. The surface should be damp but without standing water.
Mixing
Mix the product with the recommended amount of clean water using a low-speed mixer until a homogeneous consistency is achieved.
Application
Apply the prepared mortar with a steel trowel or suitable plastering equipment. Follow the recommended curing intervals between layers.
Curing and Protection
After application, protect the surface from rapid moisture loss, strong winds, and high temperatures.
