ZM-41 Smooth machine cement-lime plaster


Universal fine grain plaster, manufactured industrially in the form of a dry mixture using mineral binding fillers and modifying agents, improving the operational properties. After mixing with water forms a uniform plaster solution, easy in processing, with high adhesion to the substrate. Suitable for interior and exterior works.

Use ZM-41 of the plaster solution

The solution is designed for machine or manual application of smooth multi-layer plaster coatings directly on the walls with ceramic elements on lime-sand and concrete substrates. Allowed to use as a base coat for decorative plaster and paint.
