Opaque wood stain

  • Water-borne

Water-borne opaque wood stain based on an alkyd-reinforced acrylate binder. For outdoor use. Fine composition which gives an opaque protection while leaving the surface texture of the wood visible. Gives a water-resistant but well breathable surface. Finish: semi-matt

To be used for renewed treatment of old, faded wood stain surfaces, and also when a uniform colour is desired on old and new wood stain surfaces. Suitable also for use on new and press-impregnated wood as well as for log surfaces. Typical objects are walls, covering boards, fences, window frames, etc. May also be used for maintenance painting on most old oil and alkyd paints, if the surfaces are in good condition.

Surface preparation

NEW WOODEN SURFACE: Treat the wooden surface which is subjected to weather strain as soon as possible. At least the pre-treatments, impregnation and priming would be best done in the summer of construction. Remove from the surface all loose matter, dirt and dust. Wash dirty and/or mildewed surfaces with RENSA FACADE facade cleaner. Brush the detergent into the surface and leave it to take effect as long as possible. However, the surface must not get to dry. After this rinse the surface thoroughly with clean water and allow to dry completely. Treat the wooden surface with clear wood preservative from the WOODEX series. Allow to dry for one day. Apply by spray or brush. Treat end grain especially carefully. The surface treated with priming oil is then primed with either undiluted or 5 - 10 % diluted VISA. Allow to dry for abt. 2 h. Apply by brush. When spray painting, finish the wet painted surface with a brush. Treat end grain especially carefully. PREVIOUSLY PAINTED/WITH PRIMING OIL TREATED OR OLD WOODEN SURFACE: Replace or repair wooden parts that are in poor condition. Remove loose matter, loose or poorly adherent paint or priming oil as well as greyed or fluffy layers of wood by e.g. scraping, wire brushing or using an infra-red heater. Avoid unnecessary damaging of the wooden surface. The adhesion of an old, thick paint layer to the substrate may have been weakened so much that the paint should be removed even if it seems intact. 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 VISA. If there is doubt about the adhesion, it must be ensured by test painting. Wash surfaces with RENSA FACADE facade cleaner. Brush the detergent into the surface and leave it to take effect as long as possible. However, the surface must not get to dry. After this rinse the surface thoroughly with clean water and allow to dry completely. Avoid unnecessary wetting of the wooden structures during the washing. Bare wooden surface of the damaged parts are treated with wood preservative from the WOODEX series. Allow to dry for 1 day. After that prime the damaged parts with VISA. Allow to dry for abt. 2 h.

Application

Before use stir the paint thoroughly. In order to avoid colour differences when painting large uniform surfaces, paint of the same tinting batch should be used for the whole surface and/or mix sufficient amount of paint into the same vessel. Apply VISA by brush. When spray painting, finish the wet painted surface with a brush. Recommended nozzle size for airless spray is 0.017–0.021”. Primed or previously painted surfaces are top coated 1–2 times depending on the coarseness of the surface, the colour of the substrate and/or the the coverage of the colour. Avoid overly thick paint films on log surfaces.

Application conditions

The surface to be painted must be dry. The moisture of the wood must be below 20% of the dry weight of the wood. During the application and drying period the temperature of the ambient air, the surface and the paint shall be above +5°C and the relative air humidity below 80%. Avoid application in direct sunlight.
