PROTECTIVE COATING

CEMSCREED FAIRING COAT is acrylic polymer modified cement based fairing coat. Its main purpose is to prepare concrete surfaces prior to application of a protective coating system. It just requires addition of sufficient quantity water and ready to use. When it is applied on concrete surface, it fills the surface irregularities up to 3mm. The specially selected and formulated polymer present in CEMSCREED FAIRING COAT eliminates the curing for internal application.

CEMSCREED FAIRING COAT is ideal for filling blow holes and all surface blemishes on concrete. It can be used on concrete structures like beam, slab, column, concrete walls, etc.

SALIENT FEATURES
•Requires only the addition of mixing water
•Excellent adhesion to concrete
•Excellent resistance to freeze / thaw action and carbonation
•Reduces ingress of water borne salts, such as chlorides
•Reduces atmospheric / chemical attack
•Reduce shrinkage
•Ensures good fair-faced concrete

APPLICATION PROCEDURE

1. Surface preparation
•Remove all dust, dirt, loose particles from the surface by means of oil free compressed air.
•Remove any corrosion deposits, paint coating, oil, grease, and algae by means of wire brush or any appropriate liquid.
•Wet the surface with water and remove access water before application of CEMSCREED FAIRING COAT.

2. Mixing
•Small quantity mixing can be done in drum mixer or bucket.
•Add 1 part of water in a clean container and slowly add 3 parts of CEMSCREED FAIRING COAT in it.
•Thoroughly mix it until homogeneous and smooth mix is achieved.
•For large quantity mixing, must be done in mechanical mixer.
•Add 8.75 litre of water in mixer drum and operate the machine.
•Now add 25kg bag of CEMSCREED FAIRING COAT in that mixer and continuously mix it for 3-5 minutes until homogeneous mix is achieved.

3. Application
•Apply prepared mixture on surface in 3mm thickness with help of steel trowel.
•Let it set partly, after that, apply a smooth coat over it.
•For very smooth surface, water can be sprinkled over it before final coating.

In today world, concrete is the most used material / product in construction industry. Concrete structures exposed to atmospheric carbon dioxide emitted from various sources, in presence of moisture / water, atmospheric carbon dioxide diffuses slowly through the concrete and the process of carbonation is initiated, the pH of concrete slowly turns acidic and starts rusting the reinforcing steel bars. Anti-carbonation coatings are used as surface treatments that have a high resistance to carbon dioxide. They shield the concrete from carbonation by acting as a barrier. For example, Fairmate’s ‘FAIRCOAT’ is well known and is protecting several renowned structures in India.
Features of FAIRCOAT Anti-Carbonation Coatings
FAIRCOAT is a smooth protective, decorative anti-carbonation coating for interior & exterior surfaces with exceptional weathering characteristics. It is based on aliphatic elastomeric acrylic. It has been specially designed for the decoration and protection of concrete against attack from atmospheric carbon dioxide, airborne chlorides, acid rain, weathering etc. When it is applied on surface, it forms a flexible layer allows the surface to breath and acts as carbon dioxide barrier thus protecting the concrete in aggressive weather conditions. Properties include the following:

• Anti-carbonation properties
• Excellent waterproof coating
• High flexibility with crack bridging capabilities up to 2mm
• UV resistant
• Excellent bonding characteristic with the substrate
• Chloride ion diffusion is zero as per ASTM C 1202
• Resistance to carbon dioxide diffusion is > 50mm thickness of equivalent air layer as per EN 1062
• Non-toxic and non-flammable
• Good weathering properties (anti-algal & anti-fungal).

Concrete is a highly alkaline material and if un-carbonated it has a pH in the region of 12.6. Carbonation starts on the surface of the concrete and can ultimately reach the depth of the steel reinforcement within the concrete. The alkaline state of the concrete provides a passive resistive layer to the surface of the steel reinforcement that prevents corrosion.
Once concrete comes into contact with carbon dioxide and other pollutants within the air, then a reaction may occur. Carbon dioxide can form carbonic acid with the water in the cement that then neutralizes the alkaline state of the concrete. If this happens, then carbonation moves through the concrete as a front that gradually reduces the pH value to 8pH; neutral is 7pH. However, corrosion to the reinforcement can occur if the pH value falls below 11pH.
Carbonation occurs when carbon dioxide reacts with calcium hydroxide of concrete and deposits as calcium carbonate, which reduces the protection of embedded steel reinforcement. This, in turn, results in reinforcing steel becoming susceptible to attack by water and oxygen, causing corrosion of the steel and eventually spalling of the concrete.

Application Areas
Existing Building & Bridges: It can be applied as a protective coating in existing buildings and bridges to protect them from carbon dioxide, air borne chloride, and rain.
New Buildings & Bridges: FAIRCOAT can be applied as an anti-carbonation coating in new buildings and bridges, which will enable it to resist attack by carbon dioxide, airborne chloride, and rain.
Interior Decoration of Buildings: As FAIRCOAT is non-flammable and has excellent waterproof characteristics, it can be used in interior decoration.
To achieve effective anti-carbonation coating, a two-coat application is recommended. FAIRCOAT covers 3-4m2 per kg with a recommendation of two coats for a dark shade. The surface texture and porosity must be taken into account while estimating quantities.

Should a non-slip finish is required, a suitable silica sand should be scattered onto the first coat of SAFECORE WBCOATING whilst still wet. The following day any excess sand may be swept from the surface using a clean brush prior to application of the second coat.

Coverage : A 5 Kg pack is sufficient to prime 25 m² of surface.

Environment friendly protective and Decorative coating for interiors and Exteriors

THE BASIS OF ECO FRIENDLY PAINTS
Natural ingredients are at the heart of the unique qualities of FAIRCOAT E-GREEN. The binder is liquid silicate whose structural form and hardness is perfectly compatible with its inorganic colorants and the inorganic concrete and masonry structures it is applied to.

PENETRATION PROPERTY
The principle strength of silicate paints is their penetration within the substrate. This results in a solid mineral and insoluble compound of paint and substrate (concrete, natural stone, marble, etc). The cross-section through the render shows this penetration, which is also known as silification. This chemical bond locks the paints into the subsurface as opposed to organic coatings that sit on the surface.

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 cement based substrates, porous stone and traffic bearing surfaces. Penetration depth is influenced by the substrate’s pore structure and permeability, moisture content and surface preparation.

When FAIRCOAT E-GREEN 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.

WATER VAPOUR PERMEABILITY
The high water vapour permeability of silicate paints is due to their crystalline nature which ensures that humidity present in the masonry can freely pass from the substrate. Thus water cannot build up between the paint and the substrate – which normally leads to paint cracking/ blistering and being pushed off the surface. Instead, the substrate remains dry and the breathability of the building is maintained.

INCOMBUSTIBILITY
FAIRCOAT E-GREEN do not burn, unlike emulsion and other organic based paints. In the event of a fire breaking out, damage to the substrate is reduced and the paint does not give off any toxic fumes.

NO FUNGUS, ALGAE OR MOLD
The pure inorganic inert composition and high pH of silicate paints prevents any fungi, algae or mold growth, thus assuring a hygenic and clean paint layer. The absence of surface condensation due to the coatings high water vapor permeability, promotes a clean, healthy environment. Traditional organic paints provide smooth film coatings that do not breathe, attract moisture and fungi, algae and mold spores. Toxic mold growth is the number one health problem in building structures today. FAIRCOAT E-GREEN can improve the health of the building environment.

REGULATION OF TEMPERATURE
Silicate paints have a micro-crystalline structure, which reflects lightand heat. In hot climates this reflective property reduces the thermalstress on the structure and reduces the amount of cracking the substratewould normally undergo.

LIGHT FASTNESS
Neither harsh climates nor high UV radiation can alter the color of a FAIRCOAT E-GREEN Redecoration in the same color shade is possible after many years. Traditional organic paint coatings are subject to UV deterioration from day one, breaking down the paint film which changes the color and causes the coating to fail. Silicate paints have an extremely long life providing important economies over the long term.

ENVIRONMENTALLY SAFE
This water based Silicate paints are harmless to the environment, consisting of natural mineral compounds including quartz, inorganic mineral colorants and liquid silicate used as a binder. Silicate paints represent a technology which has no detrimental effects on the environment in terms of manufacturing as well as in terms of application. Under fire conditions no toxic fumes evolve as the FAIRCOAT E-GREEN does not ignite.

Thus FAIRCOAT E-GREEN is Breathable, Moisture Resistant, Does not contribute to growth of mold, algae or mildew, Durable and UV Resistant; does not yellow, fade or peel.
