- Water-borne
- Water-borne
A water-borne acrylate paint intended for use on interior walls and ceilings. It is easy to apply and produces a matt, even film.
BIORA 4 can be applied onto concrete, plaster, stopper, brick and building board surfaces.
Surface preparation
Clean new surfaces from dust and dirt. Wash previously painted surfaces with RENSA SUPER paint cleaner. Matt down hard or gloss surfaces by sanding and thereafter remove the dust. Remove all of the old paint from the surfaces which have been painted with glue paint or lime wash. Spray filler ceilings, which are not waterproof, are recommended to be primed with solvent borne primer e.g. FUTURA 3 Adhesion primer. For smoothing of irregularities in the surface choose a suitable filler from the SILORA series. The dried filler is sanded down and the dust removed.
Application
Steel surfaces are primed with FERREX AQUA Anticorrosive paint. Paint concrete, plaster, stopper, brick, chipboard, gypsum board and fibre board surfaces straight on with BIORA 4 wall paint or prime with BIORA 3 primer and ceiling paint. Before use stir the paint thoroughly. The paint is thinned with water when needed. Apply once or twice by brush, roller or spray. Suitable nozzle for airless spray is 0.017 - 0.021".
Application conditions
The surface to be painted has to be dry. 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%. Good ventilation during the application and drying period quickens the drying process.
