Lime paint

What is lime paint?

The lime paint produced by Tadelaktmanufaktur is a particularly breathable and environmentally friendly coating with natural antibacterial properties. Made from pure slaked lime, carefully selected additives, and high-quality oils, it offers excellent workability. The binding agent is slaked lime [Ca(OH)₂] of exceptionally high purity (98%), which is traditionally obtained from selected limestone at low firing temperatures (850–900 °C). The paint is characterized by its high diffusion capacity, is free of harmful substances, and offers natural protection against mold and other microorganisms. In addition, it is completely recyclable and can even be reused as an additive—an ideal solution for ecological construction and a healthy indoor climate.

Suitable substrates for lime paint

Our lime paint is suitable for indoor and outdoor use. Suitable substrates include:

• All mineral plasters
• Lime plaster, fresh or old
• Clay plaster

Advantages of lime paint

• Use of harmless raw materials for a healthy living environment
• Odorless and moisture-regulating
• Mold-inhibiting and fungicidal properties
• Antistatic and dust-repellent effect
• Matte, highly opaque marble white

Preparing the surface

The surface must be dry and free of separating substances such as oil stains. Loose layers should be removed with a wire brush or scraper.

Can lime paint also be tinted in different colors?

Our lime paint can be colored with all color pigments except iron mica. Up to 10 percent by weight of pigments can be added to the lime paint. For 13 kg of paint, this corresponds to 1.3 kg of dry paint. The slaked lime cannot bind a higher amount, which would cause the paint to chalk. The pigments are first mixed into a paint paste and then added to the lime paint. Instructions for making the paint paste can be found here. For a colored coat, it is recommended to apply one or two white base coats with a lime brush or roller. The colored coat is best applied with a lime brush. Unevenly absorbent substrates can cause patchy results; pre-treatment with casein primer helps here.

Consumption and application

On smooth substrates, consumption is 0.2 - 0.3 kg/m² per coat. It is recommended to apply two coats. A prior coat of casein primer helps to even out the absorbency of the substrate, facilitates application, and reduces paint consumption. The full covering power of the lime paint only becomes apparent after it has completely dried. Before painting, check how absorbent the substrate is. If necessary, light pre-wetting is recommended to enable even application. The lime paint is adjusted to the desired consistency with clean water. For the first coat, it is recommended to apply the paint crosswise with a lime brush. Once completely dry, the second coat can be applied – also crosswise, either again with a lime brush or with a suitable lime pump. If necessary, a third coat can be added. For colored variants, always work with the brush in crisscross movements to achieve a harmonious, cloudy appearance. Ensure sufficient drying time between coats. Failure to follow the application instructions may result in visible defects or technical problems.
