CLEAR COOL COAT ELASTOMERIC PAINT REDUCES HEAT BUILDUP ON WALL & ROOFS

Rainguard’s CLEAR COOL COAT is a premium quality, heat reflective paint and thermal barrier high build, 100% acrylic water-based elastomeric coating with ceramic sphere technology that provides waterproofing and insulating benefits to reduce cooling costs in the summer and heating costs in the winter that comes in a decorative clear translucent matte finish that allows the surface color to come through (it can be slightly hazy over dark accent colors only). 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. Use on new or existing surfaces including block, brick, stucco, cement, concrete, wood, metal (painted) and EFIS. COOL COAT is quick drying with excellent adhesion and hide.

As a Thermal Paint, Works Like a Liquid Pane Of Thermal Glass. Offers Both Heat Reduction And Cold Protection, Paint Film.  Reflecting infrared radiation, use on exterior walls in the summer to reduce cooling costs and on inside walls in the winter to reduce heating costs.

Can also use on skylights (recommend testing for adhesion) to cool interior rooms (see Skylight Project Example) from the summer heat with only a small reduction in lighting.

For use on windows we now offer a complete selection of interior and exterior clear film options that can reject up to 89% of IR (infrared radiation) to dramatically cool a room while at the same time reducing glare and blocking up to 100% of UV rays.  See our Heat-UV-Glare-Reflective-Window-film

Cool Coat is also available in a Ready-to-Use White Color.  For outdoor projects requiring a colored horizontal surface including pool decks, patios, porch’s 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.

Looking for more colors? View our E68 Cool Life Color Options page for additional color options.

PRIMER:  If a primer is required for Clear Cool Coat, see our AcrylicPoly DTM Primer which is available in a clear version that will not yellow and can be applied over concrete, masonry, wood, plastic, fiberglass, painted metal surfaces

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, 2nd best option is do it late in the day.

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 whitish look in Clear Cool Coat when dry.  Ceramic spheres which are mixed into the Cool Coat and are a key element in cooling the surface are lighter than the rest of the coating and tend to sit on the surface, therefore need to be thoroughly blended for best looking results when dry.

When mixed properly the Clear Cool Coat offers a translucent clear (it “can” be slightly hazy over dark accent colors only) surface. 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: 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 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.

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.
