We want to repaint on very smooth marmorino stucco coated with black soap (shiny aspect) because the color does not please us. What preparation (sanding giraffe? With what grain?), And what type of undercoat and paint to have no problem with lime?

Marmorino stucco is a plaster made of lime and marble powder. Traditionally smoothed with black soap, this coating has a very smooth and shiny appearance. Painting on such a coating is not an easy task and requires stripping, scraping and sanding. The simplest solution in my opinion would be to glue a glass cloth on this support and then apply the paint of your choice.
