Gennaro with a brush in two or three layers. Make sure the first coat is completely dry before applying the second coat. On a new plaster previously finished by blade: If the support is homogeneous just apply the product on it. If the support has to be made homogeneous use only Igea’s RASOCALCE first (see chart) then apply three or four Pittura S.Gennaro’s layers with a brush. Make sure the first coat is completely dry before applying the second coat. On old walls previously finished with chemical products: clean the whole wall carefully and energically with sandpaper, remove the dust and then apply the product. For indoor usage it is suggested to protect the paint from rain until it is completely dry.
Su intonaco vecchio, sia interno che esterno già trattato con prodotti sintetici, bisogna carteggiare abbondantemente l’intera superficie, pulire dalla polvere e quindi passare alla fase di tinteggiatura.
Per applicazione all’esterno è importante proteggere la tinteggiatura dalla pioggia fino alla totale essiccazione.

Light dark shadows or nuances are Lime’s aesthetical characteristics. Don’t apply the product on hot walls, under direct sunlight exposure or in a windy day. The intensity of the colour depends on the layer’s thickness and on the absorbing properties of the wall and its porosity. It is suggested to check the intensity of the layer’s colour once the products is completely dried.
