Used for painting all surfaces on a mineral base: ordinary cement-lime plasters, cement-lime, plasterboard, plasterboard, concrete and old resistant paintwork. The clean primer is impregnated with ADEPLAST® Primer Primer with 1: 4 dilution depending on the absorbability of the substrate, the basic rule being that after drying it does not form the film (glossy layer); small area samples will be applied. Apply in 2 coats with roller, brush or spraying.
