It’s this color that started our company. Originally conceived as a pure demonstration to illustrate historical non-toxic colour preparation as an alternative to environmentally harmful dispersion paints (ecomarket in Hildesheim, approx. 1985), it quickly developed into a bestseller which led to the foundation of our company KREIDEZEIT.
Make your own casein paint from low-fat curd cheese, soda and a chalk sump. Experience the excellent spreadability, the enormous opacity and the suitability for everyday use of this simple paint.
Casein paints are wall and ceiling paints whose binders are pure natural milk protein (casein). Even in ancient Egypt, colours were produced and processed from milk and earth pigments. The same can be seen from ancient Hebrew texts. Wall paintings in the Sistine Chapel (Secco Technique) owe their durability to the same old recipes.
Modern casein paints are produced as powders. Shelf life is extended to several years. There is no need for preservatives, the transport weight and thus transport costs are reduced to a minimum and packaging waste is minimised. Casein paints are biologically harmless throughout their entire product life cycle (raw material extraction, use, disposal). Residues of paint can even be composted.
Wall and ceiling paint for interior use. Suitable for all structurally-sound, absorbent indoor renders (clay, lime, gypsum and cement), fillers, ingrain wallpaper, pure wallpaper, paper fleece, plaster-board, gypsum fibreboards and concrete.
Also suitable for firmly ingrained, matt and absorbent emulsion paints (please always test on a small sample area first.)
For wet rooms, we recommend KREIDEZEIT Lime Paint.

When using the product, the complete Product information must be observed.
Apply a base coat to all renders, fillers, levelled drywall, concrete and old emulsion paints with Vega Primer or Casein Primer and leave to dry completely. Do not apply to paper fleece/wallpaper.
Mixing the Paint
Required are: 2500 g low-fat curd cheese, an empty 10-litre bucket, a 5-litre bucket or mixing bowl, a drill with whisk, a stirring spoon or kitchen mixer.
- Open the paint bag and take out the small red bag with soda.
- Pour 2.5 litres of cold water into the large bucket, add the white paint powder (7kg), stir vigorously with a drill and whisk and leave to stand for 2 hours.
- Dissolve the soda (red bag in the colour bag) in approx. 200 ml hot water.
- Pour 2500 g low-fat curd cheese into the small bucket, pour in the soda solution, stir thoroughly with stirring wood or mixer and leave to stand for 2 hours. During this time, the soda turns the casein into a glue.
- Pour the curd mixture into the large bucket with the paint sump and mix it vigorously with drill and whisk. The paint is now ready for use.
Adjust paint/water mixture to suit the surface; i.e. a little more water may be required for a particular application.
Application temperature at least 8°C. Stir occasionally during application.
Two coats are typically required for full opacity. Do not attempt to cover dark and high-contrast substrates with only one coat of paint; excessive application thicknesses can lead to damage to the coat-ing! Allow previous coats to dry completely before applying another coat. During the application, the wet paint is translucent; it only becomes fully opaque once drying is complete.
Using a paint brush Apply evenly with a facade brush in a criss-cross pattern.
Using a roller Apply the paint liberally and evenly in a criss-cross pattern. Then immediately use a roller in a single direction, without applying any further paint.
The Paint must be applied on the same day as mixing. Do not use paint that smells bad or rotten under any circumstances: Danger of prolonged odour problems even after drying!
Drying times at normal climate
Safe to coat after approx. 8 hrs. Thoroughly dried after approx. 24 hrs.
Good quality, medium-pile paint roller and paint brush.
Cleaning the Tools
Immediately after use with water.
Overcoating of old dispersion paints
The old paint must be stable, matt and slightly ab-sorbent. For better adhesion to the substrate we recommend an addition of 30 ml Safflower oil (low-yellowing) for 1 kg of paint powder used.
The oil is added to the readily mixed Casein Paint DIY, stirring vigorously.
Dirty dispersion paints must be cleaned before applying the Casein Paint, e. g. with soda. In these cases, the suitability of the paint should generally be tested on site by setting up a trial area.
Casein Paint DIY can be tinted with up to 10% Kreidezeit earth and mineral pigments (max. 100 g pigment per 1 kg paint powder).
• Pigment guide Wall Paints and Renders
Either stir the pigment directly into the preparation water until smooth before mixing in the white paint powder, or create a paste with a little water and then mix in with the finished Casein Paint. Instruction
