Teknos Nordica Matt Finish | White & Black

It is recommended to paint new surfaces as soon as possible. At least the impregnation and priming would be best done in the summer of construction. Remove from the surface all loose matter, dirt, dust and mildew. If needed, use RENSA FACADE facade cleaner. Apply a coat of clear wood preservative from the WOODEX series. Allow to dry for one day. Prime wooden surfaces with NORDICA PRIMER and allow the surfaces to dry for 1 – 3 days depending on the weather. Wash the metal parts with TEKNOSOLV 1621 (solvent naphtha) and prime with FERREX AQUA.

Replace deteriorated wooden parts with new ones. Remove loose matter, dirt and dust. Remove the deteriorated paint coats entirely. Note, that the adhesion of an old thick paint layer to the substrate may have been weakened, therefore the paint should be removed although the paint film looks intact. The old paint layer is removed primarily by scraping or wire brushing and possibly by heating the surface with infra-red heater designed for that purpose. Secondarily paint remover or blasting can be used. The surface of old oil paint coats may be in poor condition: heavily chalked, dusty and brittle. These types of surfaces must be carefully cleaned so, that the new paint adheres properly to the substrate. Some traditional paint types, such as red ochre paint and paraffin oil paint, produce such a brittle and dusty surface, that they can’t be maintenance painted with NORDICA CLASSIC. If there is doubt about the adhesion, it must be ensured by test painting. Wash surfaces with RENSA FACADE façade cleaner and rinse thoroughly.

Old, untreated wooden surfaces can before the priming be treated with clear wood preservative from the WOODEX series, see ‘NEW WOODEN SURFACE’. Prime bare wooden surfaces with NORDICA PRIMER. Allow to dry for 1 to 3 days depending on the weather. Wire-brush the rusty metal parts. Wash all metal parts with TEKNOSOLV 1621 (solvent naphtha) and prime with FERREX AQUA.
