Base-coat plaster made with the purest natural hydraulic lime and mineral dolomitic aggregates with a constant grading curve of between 0 and 2 mm. The product is optimised for mechanical application, is resistant to salts and guarantees full suitability and chemical inertia on surfaces and compatibility with both modern and period masonry. OPUS MEC offers long workability times and is suitable for a range of architectural solutions.

OPUS MEC is suitable for application on any brick, masonry, stone or mixed wall, or on any homogeneous and even internal or external surface, and allows for the creation of base-coat plaster on vertical walls and/or ceilings in a single layer of a thickness of 15/20 mm. Thicker applications require multiple coats of 10 mm each and in accordance with best practices and wait times to allow drying between one coat and the next. OPUS MEC has been optimised to maximise compatibility with period masonry and is particularly suited to restoration works.
