Preparation: 

Ensure Casein Distemper is within shelf-life period. All surfaces should be sound, dry, and free from dirt, oil, grease or other contamination. Previously distempered surfaces should be wiped/ washed free of any powdery surface material. Unpainted porous surfaces should be primed with a wash-coat of casein distemper diluted with 10% clean water. New lime plaster should be allowed to carbonate and dry for at least four weeks prior to application. Any fungus or mould must be treated with a fungicide and making good and filling should be carried out with a material appropriate to the substrate. Casein Distemper can normally be applied to prepared previously emulsion painted surfaces in normal domestic environments. It is not recommended that distemper be applied to emulsion and other modern paint types in poorly heated and poorly ventilated churches. Seek Technical Advice. Sample trials should be carried out well in advance to ensure that the surface is suitable for application.

Application: 

Method Two coats normally recommended. Apply by brush. Cannot be spray applied. Brushes and equipment should be cleaned with warm, soapy water immediately after use. Thinning Thinning is not normally necessary for primed or previously painted surfaces. Casein Distemper is temperature sensitive and will thicken in cold conditions. If paint has thickened, it can be returned to the correct consistency by placing in a warm room or standing the can in a bucket of hot water. Only if absolutely necessary dilute by no more than 10% (by volume) with clean water. Coverage 10 - 12 m2/litre/coat coat on smooth surface of average porosity.

Observations: 

Performance Drying: In good drying conditions: Touch dry in 4 hours. Allow 12 hours between coats.

Limitations: 

DO NOT apply in temperatures below 5°C or above 25°C. DO NOT use on surfaces previously painted with oil-based paints.
