Solacoat COOL-IT-CERAM Heat Reducing Paint Coatings

Solacoat COOL-IT-CERAM Heat Reflecting Paint Coatings: is a range of highly durable, selected topcoat colors for use on roofs where lowered roof temperatures due to better heat management are combined with appealing conventional roofing colors. The cutting-edge technology used in the Solacoat COOL-IT-CERAM Heat Reflecting Paint Coating colors permits significantly lower heat ingress to penetrate the under-roof space which then radiates through into the living/working spaces of homes and buildings while maintaining maximum durability and service life of the roof coating and the actual roofing material. Dependent upon the color selected, temperature reductions inside the living/ working areas can be between 8 - 12°C * cooler than with similar colors made using traditional roofing coatings. This reduced heat influx through the roof cavity can then be translated into much reduced demand on air-conditioning power units resulting in actual cost savings and also green-house gas emissions through reduced electricity generation. * The 8 – 12 °C temperature reduction inside homes etc relates to the heat permeated from the roof cavity which is located between the roofing underside and the ceiling. The actual temperature reduction in the roof cavity area would be around 20 - 30°C less in hot conditions than that if conventional roof coatings had been used.

Features

• Highly durable pigments resulting in extended life. Color fading resistance of up to 20 years.
• Significantly lowered heat ingress to homes/buildings through better heat management capabilities leading to internal heat reductions of 8 - 12°C inside homes/buildings.
• Selected range of architectural colors to enhance contemporary appearance of homes/buildings. Refer to color swatch.
• Cost-effective savings for the home/building owner as well as enhanced benefits for the environment. Savings of around 25 – 55% on electricity cooling costs can be realized.
• Environmentally better alternative as significantly less green-house gases are generated with the reduced need for power consumption of air-conditioners etc.
• • Low toxicity components used in these coatings making the coatings suitable for use on roofs used for the collection of tank water. See note on water tanks.

Uses

COOL-IT-CERAM Heat Reflecting Paint Coatings is eminently suitable for coating primed external metal surfaces where control of temperature extremes is paramount. It is also suitable for use on all interior/exterior surfaces including masonry, bricks, fibro cement and correctly primed timber and metals.

Surface Preparation

The Solacoat COOL-IT-CERAM Heat Reflecting Paint Coatings range is a product system consisting of one coat of primer and two coats of the selected Solacoat COOL-IT-CERAM Heat Reflecting Paint Coatings topcoat. It is only this system that will provide the longevity of the coating system combined with the reported heat reductions for these products. Omission of any coating or failure to apply the coatings at the recommended application rates will reduce the benefits and service life of these products.

Material repairs to roofs such as re-pointing of tiled roofs, replacement of cracked tiles, replacement of perforated sheets and fixing of gaps together with securing of loose sheeting is recommended prior to application of this coating system.

Surfaces must be clean, dry and free of all contamination including dirt, moss, lichen etc. High pressure water cleaning together with treatments for organic growths and/or rust following the directions for use on the relevant commercial products must be diligently exercised in order to achieve long service life of these coatings. New metal roofing requires degreasing prior to coating. Where water tanks are connected to roofs which are to be cleaned or coated, these must be totally disconnected from the roof prior to commencement of cleaning and must remain disconnected until at least 12mm of rain has fallen on the roof after the coatings have dried. Please refer the document on roofs with connected tanks.

Metal Roofs – Unpainted.

After attending to the above listed repairs/ preparation as appropriate, apply one coat of Solacoat WB Metal Primer by spray, brush or roller at a spreading rate of 10 – 12 square meters per liter. Allow a minimum of 4 hours for the primer to dry before application of the first coat of Solacoat COOL-IT-CERAM Heat Reflecting Paint Coatings topcoat at a spreading rate of 10 – 12 square meters per liter. The second coat of Solacoat COOL-IT-CERAM Heat Reflecting Paint Coatings top coat can be applied at a spreading rate of 10 – 12 square meters per liter after a minimum of another 4 hours drying period.

Metal Roofs – Previously painted.

After attending to the above listed repairs/ preparation as appropriate and ensuring that all loose or flaking paint has been removed, apply one coat of Solacoat WB Metal Primer spray, brush or roller at a spreading rate of 10 – 12 square meters per liter. Allow a minimum of 4 hours for the primer to dry before application of the first coat of Solacoat COOL-IT-CERAM Heat Reflecting Paint Coatings topcoat at a spreading rate of 10 – 12 square metres per litre. The second coat of Solacoat COOL-IT-CERAM Heat Reflecting Paint Coatings topcoat can be applied at a spreading rate of 10 – 12 square metres per litre after a minimum of another 4 hours drying period.

Tiled roofs – either concrete or terracotta.

After attending to the above listed repairs/ preparation as appropriate, apply one coat of Solacoat CP Primer by spray, brush or roller at a spreading rate of 10 – 12 square metres per litre. Allow a minimum of 4 hours for the primer to dry before application of the first coat of Solacoat COOL-IT-CERAM Heat Reflecting Paint Coatings topcoat at a spreading rate of 10 – 12 square metres per litre. The second coat of Solacoat COOL-IT-CERAM Heat Reflecting Paint Coatings topcoat can be applied at a spreading rate of 10 – 12 square metres per litre after a minimum of another 4 hours drying period.

NOTE:

• Do not apply coatings if rain is expected within 4 hours.
• Substrate temperature must be at least 12°C at application and must remain above this temperature until the coating has dried.
• Allowance to be made in the application spreading rate to allow for the roofing profile and porosity of the substrate.

Application

contents of can thoroughly with a wide flat stirred ensuring the bottom of the can is reached. Apply a full coat of Solacoat COOL-IT-CERAM Heat Reflecting Paint Coatings by brush, roller or spray at the recommended spreading rate over the appropriate Solacoat CP Primer or Solacoat WB Primer.

Brush/Roller

Pre-wet brushes and roller covers prior to use. Use a quality wide bristle brush, flow paint on generously and do not overspread. Alternatively, use a quality 12mm nap roller cover for best results. On rough surfaces, a 20mm nap roller will give better coverage but the finish may show more roller patterning.

Spray

Airless spray application is recommended. Recommend tip size is 0.38 – 0. 48 mm (0 .015 – 0.019”). If necessary Solacoat COOL-IT-CERAM Heat Reflecting Paint Coatings topcoat may be thinned slightly with water to assist application. If thinned, allowance must be made in the spreading rate to compensate for the added thinning.

Approximate coverage

Covers approximately 8 square metres per litre per coat depending on the surface porosity. To determine actual roof measurements, multiply the linear roof length by 1.25 for profiled roof substrates and the roof width form edge to apex by 1.10 for low pitched roofs (less than 10°); 1.15 for steep pitched roofs (10 to 20°) and 1.40 for very steep roofs. To calculate the actual roof area to be covered, use the following equation: Area = (Linear roof length X linear factor) X (Roof width X pitch roof factor) Example: Profiled roof 10 metres long and measured 5 meters from edge to apex on low pitch roof. Area = (10 x 1.25) X (5 X 1.10) = 68.75 square meters.

Drying Times

Approximate drying times at 25°C and 50% Relative Humidity. Touch dry: 30 – 45 minutes Recoat: minimum 4 hours. Drying times may be extended by adverse drying conditions or high film builds.

Clean Up

Clean all equipment promptly with water. Dispose of washings in accordance with local council requirements.
