Receiving surface for plastering must be sound and free from dirt, dust, grease and traces of foreign materials that will affect adhesion. Where necessary, dampen the dry concrete or rendered surfaces before application of CMI RC COATING 2781.

Add a 40 kg bag of CMI RC COATING 2781 to approximately 16.8 liters of clean water. Use a power drill to mix thoroughly. Allow mixture to stand for 10 minutes for additives to dissolve. Before using the plaster, mix again.
Apply by using a steel trowel or spatula.


Storage life is approximately 6 months if stored in a cool and dry place.
