EVERKOTE 300

Mineral Coating Systems

DESCRIPTION

EverKote 300 coatings are waterborne inorganic paints and stains based on potassium silicate binders. Potassium silicate masonry paints have been in use for over a century to provide extremely durable, breathable color coatings on all types of mineralbased substrates, including stone, masonry, concrete and cement plaster (stucco).

Two standard grades of are available:

      Penetral Low Viscosity, SemiTransparent Stains

      Patinar Medium Viscosity, Opaque Coatings

      EverKote 300 coatings are stabilized, reactive formulations which form chemical bonds within the substrate to provide long term color retention and durability.

HOW DO EverKote 300 POTASSIUM SILICATE COATINGS WORK?

EverKote 300's potassium silicate binder is produced by fusing potassium carbonate with silica at high temperature. The result is a soluble silicate, which can be dissolved in water to produce a  liquid "waterglass".

Although soluble silicates can be air dried to form a film, maximum water resistance, bond strength and long-term durability depend on chemical reactions with the substrate or added catalysts. Substrates with which silicates can react include:

    Calcium salts, typically found in Portland cement, lime and calcareous natural stones such as limestone and marble

    Silica, typically present in siliceous sandstones, silica sand, mortars, concrete and glass

    Ceramics, including brick and terra cotta

    Iron and other metals

When EverKote 300 is applied to suitable substrates, it penetrates and reacts to form a hard, insoluble silicate. It can also increase substrate hardness, particularly in cementitious materials. When applied to materials containing Portland cement, the silicate reacts with incompletely hydrated cement particles, converting unreacted calcium hydroxide (CaOH2 or hydrated lime) to harder calcium silicate hydrates.

APPEARANCE

EverKote 300 is available in over 900 standard colors. Custom colormatching is also available. Product dries to a flat (matte) finish..

APPLICATION

Always pretest a small, inconspicuous test area for color, adhesion and compatibility prior to large scale application. Allow up to 7 days cure time before judging final color. Previous treatments, including water repellents and chemical cleaning agents, and substrate composition can effect mineral coating reaction rates and appearance. Mineral coatings are natural materials and some color variation or shading is normal. Colors may tend to lighten somewhat with aging.

EverKote 300 is can be used in a one or two coat application. The first coat may be thinned with up to 10% demineralized water, followed by one or more undiluted EverKote 300 top coats. On porpous or rough substrates, however, product should be diluted as required to maintain target coverage rate. DO NOT OVERAPPLY. Allow a minimum 6 hours' drying time between coats. Extend drying time when subsrates are saturated or weather is cool and damp.

Surface Preparation

Surfaces to be treated must be clean, dry and free of dirt, dust, form oil, efflorescence, previous coatings (other than existing cement or silicate mineral coatings) and other materials which may hinder penetration and/or reaction with the substrate. Previous cementitious and silicate mineral coatings must be spot tested for compatibility in an inconspicuous area prior to large scale application.

CAUTION!:

Protect glass and other surfaces which are not intended to be coated by covering completely with polyethylene, sealing the edges continuously with heavy moisture resistant tape. Unprotected glass and other surfaces may be etched or "frosted" by contact with silicate coatings. This is a chemical reaction, which cannot be reversed by cleaning.

New Concrete, Stucco and Mortar must be allowed to cure for a minimum of 7 days prior to mineral coating application. For maximum effectiveness, surfaces must be sufficiently dry to allow the mineral coating to penetrate porous substrates. Allow extended drying time as required under cool, damp conditions.

Factors Affecting Penetration Depth

While penetration depth may not be critical for many architectural applications, greater penetration will have a significant effect on strength and durability of applications on cementbased substrates, porous stone and traffic bearing surfaces. Penetration depth is influenced by the substrate's pore structure and permeability, moisture content and surface preparation.

Application:

Mix product thoroughly before use as contents settle upon standing. Remix periodically during use to maintain consistent color and saturation.

Apply EverKote 300 by brush, roller or airless spray. Avoid product rundown. A thin, continuous film is required for nonporous substrates such as glazed terra cotta or hard stone.

Allow first coat to dry for a minimum of 6 hours before top coat application of EverKote 300. An additional minimum 6-hour period is required before application of a second top coat (optional).

Protection & Curing:

Protect coated surfaces from rain or other water exposure for at least 24 hours after application. Full cure requires at least 7 days, and colors may change in hue or intensity during this period. Do not expose treated surfaces to acid cleaners, hot water or steam cleaning.

COVERAGE:

Coverage rates can vary with surface texture and porosity. Maintain nominal coverage rate of 200 sq.ft./gal.per coat.
