    Silicate Silica Paint  HP

     

    Silicate Paint provides a long-lasting, breathable paint finish both internally and externally. It can be applied onto a wide range of surfaces, including lime and cement based renders, gypsum plasters and stonework. It can be used on both traditional and modern structures and is ideal for troublesome areas, such as damp basements.

    Silicate paints are the high-quality and professional coating materials of choice when it comes to ecological and colorfast interior and exterior coatings. Unlike the usual coating materials, silicate paint does not form a film on the substrate material but instead bonds directly with the substrate. The result is highly stable and durable coatings, with particularly convincing long-lasting color and natural effect.

    The special property of silica paint  offers diverse possibilities for exterior color design, for example, in new build work or for the restoration of historical building materials. Silicate paints are also the economic and durable alternative to conventional color coatings for interiors. The permanent, capillary-active bonding with the substrate with low resistance to water vapour diffusion ensures the extremely long lives of the mineral paints and enables a natural, coating result.

     

    The use of breathable paints is essential in traditional, solid wall constructions which may contain moisture from a range of sources.  Trapping this moisture in the walls with film-forming acrylic paints can cause serious structural and dampness problems.

    For most purposes, apply one coat of  Silicate Primer and two coats of Silicate Paint.  Silcate paint is easy to apply with a brush or roller and dries in hours (although we advise applying no more than one coat per day).

    Silicate Paint is a flat matt finish, and is available in over 250 colors

    Silicate paints have an interesting history. They were designed at the behest of King Ludwig I of Bavaria in the last 18th Century. Ludwig commissioned a paint that looked and worked like limewash, of which he was a great admirer, but was more durable in the harsh winter climate. The small pore size of silicate paint allows high water vapour permeability (breathability), while at the same time these small  pores don’t allow the larger rainwater molecules to penetrate. There are instances in Germany of silicate paints lasting 100 years !

    Like limewash, silicate paint soaks into the mineral substrate. In addition to this, potassium silicate (waterglass) reacts chemically to form a microcrystaline bond – a process known as silicification.

    Silicate paints have a comparable thermal expansion co-efficient to a mineral substrate. This minimises the stresses and damage caused by differential expansion.

    Silicate Paint has a number of advantages over other masonry paints and washes:

    ✔︎ Highly breathable paint: allowing water vapour to escape from the structure whilst being resistant to rain.
    ✔︎ Unaffected by UV light: acrylic paints can become brittle over time.
    ✔︎ Very durable: a life expectancy of many years if applied correctly onto a suitable surface.
    ✔︎ Resistant to airborne pollutants and acid rain. 
    ✔︎ Suitable for a wide range of substrates including lime and cement renders, gypsum plasters and stonework. Please contact us for advice on other substrates such as existing painted surfaces.
    ✔︎ The solvent is water rather than petrochemical – so virtually no VOCs.
    ✔︎ Scrubbable: ideal for high-traffic areas.

    Exterior / Interior Use

    The Term mineral colors describes paint coats with mineral binding agents. Two relevant mineral binders play a role in the field of colors: Lime and silicate.

    Under influence of carbon dioxide, lime-based binders carbonate, and water silicate-based binders solidify. Together they form calcium silicate hydrates.

    Lime paints (aside of Fresco-technique) are only moderately weather resistant, so people apply them primarily in monument preservation. Mineral colors are commonly understood to be silicate paints. These paints use potassium water glass as binder. They are also called water glass paints or Keimfarben (after the inventor).

    Mineral silicate paint coats are considered durable and weather resistant. Lifetimes exceeding a hundred years are possible.

     

    Properties

    Mineral paint contains aside of inorganic colorants potassium-based alkali silicate (water glass), also known as potassium silicate, liquid potassium silicate or LIQVOR SILICIVM. A coat with mineral colors does not form a layer but instead permanently bonds to the substrate material (silicification).

    The result is a highly durable connection between paint coat and substrate. Above that the binding agent water glass is highly resistant against UV light. While organic binders such as dispersions based on acrylate or silicone resin under UV over the years tend to grow brittle, chalky and develop cracks which finally result in damage to paint coats, the inorganic binder water glass remains stable. The chemical fusion with the substrate and the UV stability of the binder are the fundamental reasons for the extraordinarily high lifetime of silicate paints.

    Silicate paints require siliceous substrate for setting. For this reason they are highly suitable for mineral substrates such as mineral plasters and concrete. They are only of limited use for application on wood and metal, though. The permeability for water vapor of silicate paints is equivalent to that of the substrate. This effectively means that silicate paints do not inhibit the diffusion of water vapor. Moisture contained in parts of a structure or in the plaster may diffuse outward without resistance. This keeps walls dry and prevents structural damage. This addition helps avoid condensation water on the surface of building materials. This reduces the risk of infestation by algae and fungi. The high alkalinity of the binding agent water glass adds to the inhibitive effect against infestation by microorganisms and completely eliminates the need for additional preservatives.

    As mineral paint coats are not prone to static charging and thermo-plasticity (stickiness developing under heat), which is common for surfaces coated with dispersion or silicone resin, soiling takes place to lesser extent . For this reason fewer dirt particles cling to the surface and also can be washed off far easier.Silicate paints are incombustible and free of organic additives or solvents (DIN 18363 Painting and coating work Section 2.4.1).

    Silicate paints are highly color-tone stable. As they are solely dyed with mineral pigments that do not fade with exposure to UV radiation, the silicate paint coats remain constant in color for decades.

    Silicate paints are based upon mineral raw materials. They are environmentally compatible in manufacture and effect. Their high durability helps to preserve resources and their contaminant-free composition preserves health and environment. For this reason silicate paints have gained popularity especially in the segment of sustainable construction.

    Types

    Commonly three types of silicate paints are distinguished: Pure silicate paint consisting of two components, a color powder in dry or water-paste form and the liquid binder water glass. (DIN 18363 Painting and coating work Section 2.4.1). The processing of pure silicate paints require great experience and know-how. These are especially common for the historic area.

    Around the middle of the 20th century the first single-component silicate paint was developed. The addition of up to 5 mass percent of organic additives (e.g. acrylate dispersion, hydrophobisers, thickeners or similar) makes ready-to-use paint in containers possible. These are also called "dispersion silicate paints" (DIN 18363 Painting and coating workSection 2.4.1). The range of application for such silicate paints is significantly higher than for pure silicate paints as the dispersion allows coats for less solid substrates and/or organic composition. Above that handling and processing is simpler than pure silicate paint.

    Since 2002 a third category of silicate paints is known: sol-silicate paint. The binder is a combination of silica sol and water glass. The organic fraction is limited to 5 mass percent similar to dispersion silicate paint allowing for chemical setting and retaining of the silicate specific advantages. The sol silicate paint allows use on non-mineral plaster.[4] For these the bonding occurs chemically and physically. The sol-silicate paint has revolutionized the field of application of silicate paints. These paints can be applied easily and safely to nearly all common substrates.
