Recipe: Lime White/ Whiting/ Limewash

Lime has become more and more popular over the last years. Once considered as a rather trifling historic building material it now is more and more in use again mainly due to its excellent physical properties. Lime paints and washes are suitable for the following surfaces: lime plaster, lime-cement plaster, cement plaster, brick masonry, clay plaster, and natural stone. Lime paints and washes are not suitable for gypsum, dispersion paints and similar surfaces.

Processing

For exterior application one should avoid wind and direct sun exposure. Humid and windless weather conditions will help the lime bind. It will then slowly react with the carbon dioxide in the air. Wooden surfaces, surfaces covered with oil paint and aluminum areas should not be painted with limewash or -paint. Pre-wetting the plaster is necessary prior to the application of the limewash. You can also apply the limewash to fresh, new lime plaster, once the plaster has sufficiently cured. Dilute the Pit Lime with 3 parts of water, and apply the solution thinly with a tassel or a wide brush. Step 1#595: For exterior application one should avoid wind and direct sun exposure.

The limewash coat must be fully dry in order to become completely opaque. Usually, 3 coats are necessary, but 5 coats are even better. The rate of consumption depends on the roughness of the surface and will be around 100-150 ml/m² per coat. Step 2#242: The limewash coat must be fully dry in order to become completely opaque. Usually, 3 coats are necessary, but 5 coats are even better. The rate of consumption depends on the roughness of the surface and will be around 100-150 ml/m² per coat.

Ingredients

1 l Pit Lime (#31800)
3 l Water
Pigment

Note

Always whiten/limewash the wall in its entirety in order to avoid visible lines and edges. Limewash will never be completely abrasion resistant, but you can enhance its abrasion resistance by adding 2-5% of Casein Binding Medium (#63210) to the Pit Lime (in this case the lime has to be used immediately). You can color the limewash by adding up to 5 % lime-stable pigments. Pigments should be soaked in water one day prior to their use in limewash. The final color hue is visible once the limewash is completely dry, so pretests on a small area prior to application are recommended. WARNING Lime is very alkaline and caustic - always wear eye protection, gloves, and a dust mask!

We assume no liability for the processing instructions described above. In any case, we recommend the production and evaluation of sample surfaces.
