Biora 3 is a full matt primer and ceiling paint. It is a waterborne, odourless acrylate paint for dry indoor spaces. It gives a brilliant white finish to ceilings and a smooth primer coat, promoting the optimal adhesion of all Biora top coats. Biora 3 is light and easy to apply.
Can be applied directly onto building boards and puttied surfaces, as well as most previously painted surface.
As a ceiling paint it is safe to use as it is fully solvent free and only water evaporates from the paint film.
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 fill using a suitable. The dried filler needs to be sanded down and the dust removed.

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".
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 sholud be above +5 °C and the relative air humidity below 80 %. Good ventilation during the application and drying period quickens the drying process.
The final forming of the paint film takes about 4 weeks under normal circumstances and after that the ultimate durability and hardness is reached. Before this the painted surface must be treated with care. Cleaning by moist wiping or with detergents damages the painted surface. Dry cleaning methods, such as careful wiping, brushing, vacuum cleaning etc., must be used for dirty surface.
