COOL COAT ELASTOMERIC PAINT REDUCES HEAT BUILDUP ON WALL & ROOFS

Rainguard COOL COAT Ready-to-Use White is a premium quality, heat reflective paint and thermal barrier high build, 100% acrylic water-based white color elastomeric waterproofing coating with ceramic sphere technology to reflect infrared radiation that provides insulating benefits in both the summer and winter.  Over 200% dynamic elongation and recovery strength ensures that the coating will move and flex with the thermal changes of the masonry surface to help prevent rupturing or cracking.

COOL COAT is vapor permeable yet resists the effects of wind driven rain.  It restores and beautifies damaged masonry surfaces and unifies color and texture on new surfaces.

Comes standard in white color with a Satin Gloss Finish.  COOL COAT also comes in a  Clear Satin Gloss. Use on new or existing surfaces including block, brick, stucco, cement, concrete, wood, metal and EFIS. COOL COAT is quick drying with excellent adhesion and hide.

For outdoor projects requiring a colored surface including pool decks, patios, porches or other horizontal surfaces that require up to a 25% to 30% cooler surface, we offer our E28 Cool Life Deck Coating | Infrared Heat Reflective Technology Available in 12 Pre-tinted Colors

As a Thermal Paint, Works Like a Liquid Pane Of Thermal Glass. Offering Both Heat Reduction And Cold Protection Paint Film.  To cool in the summer apply on exterior walls or roofs to keep heat out  and in the winter to keep heat from escaping outside apply to interior walls.  Cool Coat is an effective insulator by reflecting infrared radiation from whatever surface it is applied to since most heat is transferred by infrared radiation.

Great Customer Reviews:

“We live in a hot climate and our garage side door gets full sun all day and gets very hot, heating up the garage. We used the Cool Coat Thermal Paint on it and now it stays cool all day, bringing the temperature of the garage down considerably. We can’t believe the difference it has made”

“Very satisfied with product…easy application, easy cleanup. My building is not completely covered yet, but can I already see a difference with the thermal aspect of this product”

“Excellent product, easy paint to work with and once I finished painting I was happy with results”

“Very impressed with how much cooler my aluminum shed is now”

Primer:

For painting bare ferrous steel, galvanized steel, aluminum first prime with a corrosion resistant metal primer such as Plugger Universal Primer.  Plugger Universal Primer can also be used on porous concrete, brick, stucco and previously painted surfaces when a primer is needed prior to application of Cool Coat Thermal Barrier Coating.

For smooth, slick, non-porous surfaces such as vinyl, plastic, polycarbonate, fiberglass, glass recommend bonding primer like Extreme Bond Primer.

The solar reflectance, thermal emittance and SRI value of a wall or roof surface are important surface properties affecting temperature, which, in turn, drives the heat flow through the wall or roof. Cool Coat test results below demonstrate its effectiveness.

Solar reflectance determines the fraction of the solar radiation incident from all directions that is diffusely reflected by the surface. The higher the solar reflective value the more efficient the product is in reflecting sunlight and heat away from the building and reducing roof and wall temperature.

Thermal emittance describes how well the surface radiates energy away from itself as compared with a blackbody operating at the same temperature.   In warm and sunny climates highly emissive roof and wall products can help reduce the cooling load on the building by releasing the remaining heat absorbed from the sun  Scientists use a number between 0 and 1, or 0% and 100%, to express emittance (the higher the number the more effective the coating).

Solar Reflective Index (SRI)    SRI is calculated by using the values of solar reflectance, thermal emittance and a medium wind coefficient.  The higher the SRI value, the lower its surface temperature and consequently, the heat gain into the building

COOL COAT is supplied ready to use. Mix contents thoroughly prior to application. If material becomes too heavy to spray, thin with up to 1 quart of water per 5 gallons of material. To prevent skinning, cover pail with a damp cloth. Apply materials to properly prepared and primed surfaces. Apply COOL COAT to surfaces at the recommended coverage rates depending on surface type and porosity. Cool Coat is a 2 coat system.  Follow recommended coverage rate guidelines for each coat for best results.

On hot summer days, to avoid problems, recommend applying 1st coat in the early morning and 2nd coat following morning.

Mixing Mix thoroughly for several minutes to completely blend the ingredients.  For a larger 5 gallon pail, recommend using a drill mixer for 5 minutes.  Insufficient mixing can lead to a uneven color.  A great mixing tool for best results in mixing high viscosity coatings is the Jiffy Style Drill Mixer.

All Surfaces: Moisture content of surfaces shall be less than 15% moisture as measured with an electronic moisture meter. New concrete and masonry construction shall be allowed to cure for 10 days to neutralize alkalinity and release residual moisture. All surfaces shall be structurally sound, clean and free of dirt, grime, efflorescence, lime run, construction debris, form oils and release agents, chalked materials, loose and peeling paint, mold and mildew or other surface contaminants, etc.

Wood: Properly clean and prepare wood surfaces. Pre-treat knots with stain blocking primer material. Prime surfaces.

Metal: Etch or otherwise clean metal surfaces and prime with appropriate metal primer.

Previously Painted Surfaces: Remove chalk, grime, loose and peeling paint and other contaminants. Repair surface and mortar joint defects. Allow patching materials to cure prior to application of primers.

Spray Application: For easiest application on larger projects suggest using a sprayer.  Spray apply COOL COAT to surfaces using a crosshatch spray pattern. Back-roll materials into surface to create a uniform and pinhole free surface film. Be sure to angle the spray tip from a point higher than the surface to allow coating to build proper mil thickness.

For airless sprayer recommend between a 5-15 (slower application and easier to control – good for beginners) to as large as a 5-19 spray tip (the 5=10″ fan pattern and the 19=.019 orifice opening for faster application recommended for experienced users wanting to spend less time).  Use any airless sprayer.  Pressure adjustment based on based on pump used and hose setup and tip size.

How to Setup Your Spray Pump For a Perfect Spray Pattern

Roller: Apply 2 coats to surfaces at the recommend coverage rate for each coat to create a uniform and pinhole free surface. Re-coat time in 4 hours or more.  In climates with significant summer heat suggest 24 hours between coats, applying in cool of morning or late in the day when both surface and air temperature is at its coolest.

PRECAUTIONS & LIMITATIONS 1. All surfaces to be coated should be clean of any dirt and grime, efflorescence, lime run, form oils and release agents, grease, mud, excess mortar, and mold and mildew, etc. 2. All cracks should be pointed or caulked. All voids, bee holes, masonry surface defects and openings such as conduits, pipes, drains, door frames, vents, air conditioner openings, electrical openings, control joints, or any dissimilar materials should be repaired using urethane or other approved patching.

STORAGE Store materials in a well-protected area between 45° and 90°F. Avoid freezing temperatures, direct sunlight, and moisture. Keep away from heat sources.
