ALABASTER FARG started in a small factory in Broby south of Sweden. Since then a lot has happened. Today you find us in a big old farm with beatiful buildings and environment in Klågerup outside Malmö. Here we benefit from much bigger production facilties, great logistics and experienced personel. Also another paint company, CODEC FARG, has the same location since many years.

THE BENEFITS OF THE SILICATE PAINT
The genine silicate paint is resistant to the acids formed by carbon dioxide, sulfur dioxide, sulfur trioxide and nitrogen oxides. Through the paints silicatization with the mineral substrate it is protected from acid rain and degradation.
Environmental friendliness. The genuine silicate paint does not smell and is free from solvents and biocides and does not emit gases.
Light fastness. Only inorganic pigments (mineral oxides) are used for highest color stability to withstand degradation from UV radition.
Chemical anchoring. The binder is liquid potassium silicate. The genuine silicate paint binds through silicatization to mineral substrate. Between the silicate paint and the substrate water insoluble silicate based compunds (similar to cement) are formed with outstanding durability as a result.
High permeability. The genuine silicate paint has high vapor diffusion openness. This means that moisture in the housing is released unobstructed and the walls ability to ventilate moisture is not hindered. As a result, no moisture is formed between the paint and the substrates and therefore there is no risk of flaking.
Mold inhibiting. The high vapor permeability prevents moisture formation and thereby inhibits mold formation. In addition, the genuine silicate paint has a high pH (11-12), which in itself inhibits mold growth and contributes to healthy homes that breathe.
Fireproofing. With silicate paint on wood indoors, improved fire protection is achieved by delaying fire. This because of the silicate paint (see Kristallat) consists of 100% of mineral non-combustible material.
CHEMISTRY BEHIND THE SILICATE PAINT
Pure silicate paint consists of fused quartz sand and potash, called water glass, with the addition of inorganic color pigment and water. Water glass is the paint binder.
Water glass is produced by expelling carbon dioxide (CO2) from a mixture of quartz sand (SiO2) and potash (K2CO3). The process takes place at high temperature and high pressure according to:
SiO2 + 2K2CO3 → Si(OH)4 + 2CO2
The carbon dioxide to the right of the formula goes into the air and what is left is called potassium silicate (Si (OK) 4) and is therefore water glass.
Silicate paint is made by mixing water glass with mineral color pigment and water. The water layer is capillarily sucked into the pores of the substrate. With the help of carbon dioxide in the air and the lime in the substrate, it is gradually transformed into quartz and calcium silicate hydrates.
The silicate paint is part of a chemical bond, a silicatization, with the mineral substrate, and therefore differs from the film-forming colors.
A plastic dispersion such as acrylate can be added to the silicate paint. Acrylate binds physically to the substrate via an adhesion process similar to glue. But acrylate is also a film-forming binder. If too much is added, the properties of the mineral substrate will be destroyed and the color will appear as film-forming color.
ABOUT ALABASTER FARG
The idea of ALABASTER FARG began at Källstorp Gård next to Västra Klagstorp in Skåne. All the façades of the farm, the marble cross (serponit) and the lime had to be redone.
My chemistry background and experience in developing products as well as renovating houses allowed me to start studying old German patents about genuine silicate paint and water glass. Through smaller experiments in the kitchen at Källstorp and some quick attempts, the first Alabaster Silicate product saw the light of the day.
First out, Källstorp Gård became dazzling white in the Skåne landscape. Then the neighbouring farm, Backens Gård, was painted with Alabaster Silicate. Since then, Alabaster's paints have been put into the market through collaborations with a number of construction companies in Österlen.
To expand and improve the logistics around my manufacturing, the construction of a small factory began in the summer of 2014. It is tailor made for the purpose and is built with natural materials and recycled materials.
The structure consists of plastered leca built on a 15 cm thick concrete floor. Old windows come from Folkes Bygg's building store and old double doors are from the old main building in Glimminge. The roof chairs are made of wood from a dismantled outdoor space from the villa in Knislinge. The factory is insulated with the hygroscopic sheep wool insulation.
The wood ceiling was painted with KRISTALLAT, which gives a fire retardant effect with its 100% mineral composition.
