FAIRCOAT DAMPPROOF – DAMPPROOF COATING FOR INTERNAL WALLS, CEILINGS AND RCC WATER TANKS

Why do we need water proofing? There is a simple answer to this.
Water proofing is required to stop the ingress of water in the structure making it water resistant. It acts as a protective coating from other elements as well such as oil and grease, chemical attacks, acid rain etc. The dual purpose of Faircoat Damproof allows us to achieve both our purposes of waterproofing and protective coating.

Faircoat Dampproof is best suited when used to protect the internal wall, ceilings etc from all possible attacks of dampness, leakage to the structure & also when you need an antimicrobial coating. It is widely used to prevent any leakage of oil and chemicals from bund areas where large quantity of such harmful substance is stored. We all have come across external walls where graffiti art is done which is extremely difficult to remove. Faircoat Damproof is the absolute solution, as it is easily cleanable and hygienic. Hence, maintaining the clean look of the structure.
Being environmental friendly and of very low odour is it easy to apply.

Faircoat Dampproof is a 2 component material off white colour material. The Base and hardener is required to be mixed using a mechanical tool. The component can be thinned down by adding water to it, not more than 20-30% by volume of total material. To make the surface more even and to achieve a putty like finish add white cement by 20-30%.

Before applying Faircoat Dampproof to the structure it is necessary to make sure that the substrate is completely free from any kind of contamination such as oil, grease, paint etc. After the surface cleaning is complete, it is required to fill all the hole on the substrate cause by air trapped on the face of the formwork during pouring or any kind of pin holes present using Fairscreed VF (a concrete repair compound).

Minimum two coats are required to achieve the desired results. The pot life of Faircoat Dampproof is 80 minutes at 20ºC. Apply the first coat using a spray (airless), brush or roller. After the application of first coat to achieve a non slip finish spread silica sand on the wet surface and let the surface dry for a minimum of 18 hours before applying 2nd coat. The overall thickness of both the coats shall be 200-250 micron, with and approximate coverage of 0.20 – 0.25kg/m2.
In case the substrate is in damp condition a priming material such as Safecore WB primer shall be applied before the application of 1st coat of Faircoat Dampproof.

Salient Features:
• Provides excellent resistance to water, oil , grease and other solvents etc
• Odourless material
• It is Non flammable, Non toxic and Non- Hazardous
• It is easily cleanable and possesses anti fungal properties
• It can be applied on both dry and damp surfaces
• Have good adhesion to concrete

Mixing Method:
1) 4 Liters of clean water per 25 kg bag of grout.
2) Add the powder component to approximately 80% of the total amount water component while mixing.
3) Add the remaining 20% of the water component to the grout at a steady rate while continuing to mix.
4) Mix until the grout appears homogenous (3-5 minutes). Allow to stand so any entrapped air can escape. Do not add more water to increase flow of the grout if a mix has stiffened due to time delays. If the grout is unworkable discard.

FAIRCURE WC – WHITE PIGMENTED CONCRETE CURING AID

Buildings have major environmental impacts over their entire life cycle. Resources such as ground cover, forests, water, and energy are depleted to give way to buildings. A green building depletes the natural resources to the minimum during its construction and operation. The aim of a green building design is to minimize the demand on non-renewable resources, maximize the utilization efficiency of these resources, when in use, and maximize the reuse, recycling, and utilization of renewable resources. It maximizes the use of efficient building materials and construction practices; optimizes the use of on-site sources and sinks by bio-climatic architectural practices; uses minimum energy to power itself; uses efficient equipment to meet its lighting, air-conditioning, and other needs; maximizes the use of renewable sources of energy; uses efficient waste and water management practices; and provides comfortable and hygienic indoor working conditions.

PERVIOUS CONCRETE

Pervious Concrete is a special type of concrete that has a high porosity so that water can percolate through it easily. The major advantage of this type of concrete is that it can be used in the areas where it is very important to remove the stagnant and there is no proper draining facility for removal of water.

The pervious concrete is made only by implementation of course aggregates and cement for binding the aggregates. The fine aggregates are not used so that the pores between the course aggregates are not blocked. This pore serves as a gateway for the water to percolate through the concrete substrate.

Pervious concrete is used in parking area, subways and residential streets and walkways. The pervious concrete s used in a wide range for stromwater management. It is one of the sustainable product and concrete of future generation.

History Pervious concrete was first used in the 1800s in Europe as pavement surfacing and load bearing walls. It can also reduce city temperatures and alleviate urban hot island phenomena. Pervious concrete was first invented in Britain in 1824. It was first introduced into the United States in the mid-1970s and has since been rapidly developed. The Sponge City was introduced in China in approximately 2012.

Need of Pervious Concrete A large amount of rain water ends up falling on impervious surfaces such as parking lots, drive ways, sidewalks rather than soaking into soil. This creates an imbalance to the natural ecosystem and leads to the host of problems such as erosion, flood, and groundwater level depletion and pollution of rivers. The best solution to avoid this is to alter the impervious construction surface such as concrete and asphalt by the pervious concrete. Pervious concrete also acts as a filter which removes the debris from the flood to enter into the rivers and ground water and recharge the water level.

Properties of Pervious Concrete It has just enough cement paste to bind the aggregate with each other. The aggregates that are used should be only course aggregate and fine aggregate is avoided.

Fresh Concrete Property: The plastic pervious concrete mixture is stiff compared to traditional concrete. The slump that is measured is 30 mm which is enough for placing the concrete.
However, slump of pervious concrete has no correlation with its workability it is not be specified as an acceptance criterion.

Hardened Concrete Property:
The density of the concrete is found to be 1800 kg/M3.
The void contents of the pervious concrete ranges from 20 to 25%.
Permeability:
Typical flow rates for water through pervious concrete are 120 L/m²/min.

FAIRCOAT Anti-Carbonation, Protective, Decorative Coatings for Interior & Exterior concrete surfaces

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.
