• For concrete and plaster, wash surface with water under high pressure, let dry, then apply one thin coat of Wall Primer (<50 µm).
• If the old coating and/or its substrate have blisters or other defects, it would indicate that total removal of the old coating is advisable. Remove by mechanical means or by stripping with Paint Remover. On powder old coatings, apply 1 coat Clear Binder.
  If substrate shows presence of fungi or algae, please proceed with the following surface preparations:
• Apply FUNGICIDAL WASH by roller and leave to react for 12h minimum. Rinse with high-pressure water again. Brush if necessary. Once dried, apply a coat of Fungicidal Treatment on the surface which will be coated the same day. Apply a thin coat of Clear Binder where necessary and leave to dry for 3h minimum. Apply 1 thin coat of WALL PRIMIER.

Apply two coats by roller or brush onto clean, dry and sealed surface.
