Novaprimer is a water-based acrylic sealer which ensure insulating performances even if in contact with highly alkalinity plaster coatings. Novaprimer represents the expression of Novacolor commitment to the environmental sustainability. To reduce the "carbon footprint", Novaprimer is formulated with a special binder, made from sustainable biomass, that replaces the fossil raw materials. This is possible thanks to a technical-productive system called “mass balance approach” certified REDcert².
