Keim Granital-System Advantages
Keim Granital - the "generation paint"
Environmentally friendly: Keim Granital is a silicate based top quality exterior paint and very suitable for buildings, considering building physics. In the production of Kem granital, the same inorganic pigments, fillers and liquid silicates are used as in the production of 2-component silicate paints. Keim Granital therefore is environmentally friendly in its production, during application and throughout its lifespan. Through the use of a minimum of organic additives, this silicate paint becomes an optimally applicable 1-component facade finish.
Protective: Keim Granital protects the substrates against heavty weather conditions and aggressive environmental influences. This silicate based exterior paint penetrates deeply into the substrate, thus creating a solid mineral insoluable compound with the substrate. Brittle and sanding may be consolidated in the most natural of ways. Keim Granital does not form a film and therefore retains a high vapor permeability in combination with a very good water repellency. Moisture inherent in the building material can therefore evaporate unhindered to the outside. Because of its mostly inorganic composition and high alkalinity, Keim Granital has a natural protection against growth of microorganisms. Keim Granital finishes are highly weather and heat resistant and incombustible.
Lightfast:: Keim Granital paints are supplied in ove 250 standard, historic and natural stone color shdes. Special color requirements can also be met if color samples are submitted. The matt and mineral-like appearance of Keim Granital paints allows te natural appearance of the facades to be retained. An unlimited variety of absolutely lightfast paints provides answers to all requirements. The repertoire and the possibilities extend from large surface area facades to paintings, from the darkest of dark to the lightest of pastel shades. Keim Granital can be quickly and easily tinted by using the lightfast Keim Tinting-Concentrates, therefore providing optimum possibilities for your color designs.
Economical:: Keim Granital paints form an insoluble compound with the substrate and are resistant to aggressive environmental influences. This, amongst other things, is a reason for the exceptionally longlife of Keim Granital finishes. Many years of durability is a factor of importance for economic viability, when one takes into account the high costs of wages and scaffolding. Keim Granital paints are easy to apply. Optimum appicatin properties, even on difficult substrates, excellent leveling properties and perfectly homogenous drying, together with low material consumption are all further arguments in favor of their economic viability. A furher cost saving factor of Keim Granital finishes istht it can be recoated without any problems.
Substrate Preparation :: Keim Granital can be used on all mimeral, clean, solid substrates without prior preparation . Extremly sintered renders are pre-treated with Keim Lime-Remover. Old, film-forming finishes which prevent water vapor permeability or which cannot take the new coating are removed with Keim Bio-Stripper or by mechanical methods. Old organic finishes which can take up a new coating must first be treated with an application of Keim Contact-Plus as a bridging coat. In the case of difficult substrates such as repaired renders or hairline cracks or diffeences in textures, Keim Contact-Plus or Granital-Grob are used as priming coats. In cases of extreme moisture and for fair-faced brickwork, we recommend a pretreatment with Keim Silan-Primer. Surfaces not to be treated should be covered up. Do not apply on heated surfaces or under direct sunlight, or at temperatures below 5 degrees C.
Work Procedure :: The priming coat is applied by brush, whereby Keim Granital is diluted with approx. 20% Keim Spezial-Fixativ, depending on the absorbtion property of the substrate. The paints must not be diluted wit water. After waiting 12 hours, the interim coat or th final coat is applied. The final coat is applied undiluted. It can be applied by brush, by roller or airless spraying equipment ()0.79 mm nozzle).
