NEW WOODEN SURFACES: Treat the surface 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. PREVIOUSLY PAINTED OR OLD WOODEN SURFACES: Change 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 this product. If there is doubt about the adhesion, it must be ensured by test painting. Wash surfaces with RENSA FACADE facade cleaner and rinse thoroughly.

Reserve a sufficient amount of paint in the same vessel for each uniform surface. Colour differences will thus be avoided. Stir thoroughly before use. Apply once or twice. The best weather resistance is achieved by applying 2 layers.

The surface to be treated must be dry. The moisture content of the wood is to be below 20%. During the application and drying period the temperature of the ambient air, the surface and the product shall be above +5°C and the relative air humidity below 80%. Avoid application in direct sunlight. Paint contains components which slow down the bleeding of extractives from the wood, but in the painted surface there could appear discolouration from knots which is typical to wood.

Must not freeze.

If the product is applied by airless spray, the surface is to be finished by a brush to ensure the adhesion. Recommended airless spray nozzle is 0.015–0.021”.
