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 clear translucent matte finish that allows the surface color to come through (it is not a water clear decorative coating). 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.
Cool Coat is also available in a Ready-to-Use White Color and in 3 different tint bases which can be tinted to a wide range of colors by your local paint store. Custom colors require first selecting your desired color and then choosing the appropriate Cool Coat Tint Base; pastel, deep or accent depending on what color you are wanting to create. Then your local paint store will mix with the same water based colorant they use to tint other acrylic paints.
WHERE IS CLEAR COOL COAT USED?
- Construction & Remodel Projects: Exterior Building Walls, Sloped Roof Surfaces Not Subject To Ponded, Pooled Water (Contact Mfg To Confirm Application If Questions)
- Interior And Exterior Walls
- Painted Metal Roofs
- Painted Metal Handrails
WHY CLEAR COOL COAT?
- Clear protection – allows underlying surface color to be seen (not water clear)
- Reflects Infrared Radiation Using Advanced Ceramic Sphere Technology

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.
OPTICAL PROPERTIES
| TESTED | SOLAR REFLECTANCE AT AIR MASS 1.5 | THERMAL EMMITANCE AT 300K |
|---|---|---|
| Cool Coat | .812 | .875 |
| Uncoated Sample | .653 | .040 |
SOLAR REFLECTANCE INDEX (SRI)
| CONVECTION COEFFICIENT | COOL COAT | UNCOATED SAMPLE |
|---|---|---|
| Low, 5 W/m (2) K | 101 | 6 |
| Medium 12 W/m 92 K | 101 | 45 |
| High, 30 Wm (2) K | 101 | 63 |
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
