MONODUR is a transparent, colorless, insulating, acrylic-based binder primer for building paints. It is suitable for all surfaces that will be coated with plastic, acrylic water or solvent paints, Relief and insulating materials, as well as trowel surfaces. More specifically for surfaces made of concrete, plasterboard, plaster, plaster, chipboard, bricks, as well as for all old surfaces that have a strong adhesion problem because they were painted with lime, watercolor or poor quality paints. It stands out for its ability to isolate dirt and not let it pass into the final colors. It is the ideal solution for priming the surfaces before applying the final colors. It also has high resistance to alkaline surfaces, waterproofs them and ensures strong adhesion and high penetration into the pores of the surfaces. MONODUR replaces the traditional way of priming with linseed oil.
