Massis Ameryah

Massis Ameryah is a traditional gypsum binder extracted from Barkan quarry used for multi-application - nonstructural civil works- such as floor covering, additives for sand & cement mortars, marble fixing, etc.

Key facts

  • Fast setting stucco
  • Pre-mixed powder -only addition of water is required
  • Economic
  • floor covering as a protective layer
  • Marble fixing
  • Additives for sand & cement mortars to accelerate setting time



Substrate must be sound, free from dust, loose particles, cement laitance, curing compounds, oil, grease or any other contamination.

Ensure the mixing container and the application tools are clean especially form waste of previous mix and it’s recommended to clean the tools directly after usage.


Massis Ameryah is sprayed on water with the right ratios (Don’t add water to powder), then leave for 2 mins till it soaks completely. Stir the mix perfectly in all directions till reaching a homogeneous mortar with the convenient consistency for the application. It is preferred to use mechanical mixing.

After preparation and mixing, apply the Massis Ameryah for the required purpose
