Restone® Silicate Chalk Single Stick, Colour-No. S 075
System Bohring / Patent 2000.
Colour system developed for the special requirements of stone restoration in terms of colour selection and yield. The colours correspond to the KEIM Natural Stone Shades.
Painting technique for a weatherproof colour application in pastel character, primarily developed for use on mineral, inorganic substrates such as lime and lime-cement plaster, concrete, stone, unglazed terracotta, glass (blasted or etched). Can also be used on all other surfaces that allow abrasion, e.g. wood and paper.
- Weatherproof, i. e. can also be used for outdoor applications and fixed permanently
- Lightfast pigments
- Smudgeable
- Without organic additives, i. e. purely mineral
- Stick size: approx. 14 x 4 x 2.5 cm
Silicate chalks differ from all chalks in that pigments, binders and fixatives are of pure, anorganic mineral. Due to the production with lightfast pigments and potassium water glass as binding and fixing agent, the colours obtain their high luminosity and weather proofness. Increasingly, silicate chalks are also being used in stone restoration. The Restone® silicate chalks were developed for these special requirements and differ from conventional silicate chalks in terms of colour selection and yield. The large sticks are available in 57 shades plus six additional special shades.
This painting technique was developed by restoration specialist Lothar Bohring specifically for use on mineral, anorganic surfaces, such as stone, lime plaster, concrete non-enameled terracotta and glass (blasted or etched) and a patent was applied for in 1996. Also suitable, of course, for use on wood, paper or any other abrasive material. Silicate chalks allow new design variations like linear drawing, flat, thinned colour applications and smudging using akapad sponge or wet working in with a sponge or brush.
It is important to choose the appropriate fixative, which should always be sprayed. Silicate chalk FIXATIV made of modified potassium water glass is suitable for purely anorganic-mineral substrates. As an alternative, silicic acid ester can also be used as a fixative on sandstone. Acrylic-based silicate chalks UNIFIX is suitable for non-mineral substrates.
Until fixation, the colour application can still be corrected or removed. After fixation has been completed, it is possible to continue working on it with silicate chalks.
