• If the old coating and/or its substrate have blisters or other defects, then old coating removal must be done 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 POLYCOLOR FUNGICIDAL WASH by roller and leave to react for 12 hours minimum. Rinse with high pressure water. Brush if necessary. Once dried, apply a coat of POLYCOLOR FUNGICIDAL TREATMENT on the surface which will be coated the same day. Apply a thin coat of POLYCOLOR CLEAR BINDER where necessary and leave to dry for 3 hours minimum. Apply 2 coats of IZYCOLOR WHITE, leaving each coat to dry 3 hours minimum.

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