High-quality, ready-to-use filler based on “dispersed white hydrated lime”
Coating, varnishing and hydrophobisation
Rediscovering tradition on the basis of dispersed white hydrated lime
At the end of the 1990s, a new treatment technique for lime was developed in the ‘Restoration and Conservation of Art and Cultural Assets’ department at Cologne University of Applied Sciences. Dispersing combines the familiar and proven properties of lime as a binding agent with the possibilities of modern technology in order to eliminate the classic disadvantages.
Advantages of the Historic lime colour system
- Accelerated carbonation (hardening)
- Increased binder capacity for pigments
- Increased substrate adhesion
- Wipe resistance
- Increased weather resistance
- Improved application properties
- Improved mixing properties of all system components
- Without plastic additives

Remmers silicate paints
Mineral paint with fine-grained quartzite texture
The classic silicate or mineral paint is surrounded by the myth of high-quality design and durability. The reason for this is the mineral binder, water glass, as well as its numerous applications in outstanding architectural monuments, particularly of early modernism. Towards the end of the 19th century, water-glass-bound painting and coating systems opened a new chapter in paint chemistry and technology, providing a qualitatively and quantitatively suitable means for long-lasting and weather-resistant artistic façade designs.
Water glass is essentially dissolved glass in water. A distinction is made between potassium water glass and sodium water glass. For paint production, only potassium water glass (paint water glass) is suitable. The drying process of a silicate paint occurs through the evaporation of water and by absorbing carbon dioxide from the air. During this process, the water glass "silicifies" and binds the pigments to the substrate. To prevent overly hardened surfaces, only relatively solid plaster substrates should be painted with silicate paints.
The natural, mineral color pigments are absolutely lightfast and weatherproof. Due to their binder, water glass, silicate paints appear matte but particularly "bright." The color selection is limited by the water-glass-resistant, inorganic pigments and therefore corresponds more to the colours of historical architecture. Colour variations may occur due to uneven drying conditions and do not represent a defect. Silicate paints are regulated under DIN 18363. They are among the most breathable paints available. For use on facades, they are usually equipped with hydrophobic properties.
Remmers silicone resin paint system
The reversible alternative against moisture
An alternative to structural water repellency through hydrophobic impregnations is the opaque or clear Remmers silicone resin paint system. The outstanding property of silicone resin paints lies in their microporous structure.
This is evident in their performance metrics. A diffusion resistance value of approximately 150 is achieved, which corresponds to an sd-value significantly below 0.10 m. This makes them comparable to commonly used single-component silicate paints. The capillary water absorption of the normal paint layer reaches the low value of 0.035 kg/(m²h⁰.⁵), providing optimal protection against driving rain, surpassing all silicate paints and most dispersion paints.
More transparency through adjustable varnishing evel
In accordance with monument preservation guidelines or client preferences, the varnishing level of Remmers silicone resin systems can be adjusted. The binder base of Color LA Add transparent, similar to true silicone resin paints, is a combination of silicone resin emulsion and pure acrylate dispersion.

Advantages of Remmers silicone resin paints and varnishes
Funcosil impregnation
Reliable protection for dry masonry
Water plays a central role in the weathering of mineral building materials. The aim of a hydrophobic impregnation is to significantly reduce capillary water absorption, as occurs during watering or exposure to splashing water. It is a sensible, preventive measure to avoid damage (prophylactic) when the capillary uptake of rainwater or splashing water can trigger or accelerate a damage process, or when corresponding damage is already observable.
Additionally, reducing the moisture content improves the thermal insulation of the facade masonry. With Funcosil hydrophobation, you can protect your bricks from damage and save valuable energy. The effectiveness of hydrophobic impregnation is based, regardless of the composition of the active substance, on a reduction of the adhesive forces between the pore walls and the penetrating water molecules.
By reducing this interaction, the normally prevailing capillary suction is transformed into a capillary depression. The range of variations and properties of hydrophobic agents based on silico-organic compounds is very broad. Therefore, the chosen agent must be matched to the requirements of the substrate. In the past, hydrophobic agents were always liquid and thus only conditionally suitable for weakly absorbing bricks. With the Funcosil FC cream technology, which allows all substrates to take in the necessary amount of protective agent over time, Remmers has solved this problem.
