NIGRA PADOANA is a prepackaged plaster made of air lime and natural hydraulic lime, that faithfully reproduces the historical mixture typical to the Veneto (around Venice) area.
With carefully chosen raw materials, faithful to historical originals, the outcome in an extremely breathable plaster, with a low content of water-soluble salts.
Depending on the type of masonry, e.g. stone, solid brick or new porous block – in order to improve the adhesion of the plaster or to better protect the masonry itself – the application of a base layer made of natural lime and pozzolans called RINZAFFO MGN might be necessary.
