Toxicity : Chemically inert and non-toxic.
Mixing ratio : Approximately 42% water on dry material.
Packing : 25 kg.


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 WALLSKIM 488.

Add a 25 kg bag of CMI WALLSKIM 488 to approximately 10.5 liters of clean water. Use a power drill to mix thoroughly. Allow mixture to stand for 1O minutes for additives to dissolve. Before using the plaster, mix again. Apply by using a steel trowel or spatula. CMI WALLSKIM 488 should be applied as a smooth finishing plaster for rendered or base coat plaster when the surface is damp or touch dry. This should result in a consistent colour finishing with minimum shrinkage cracks visible.


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