How Does Rhino Shield Perform Against Wind-Driven Rain?
Rhino Shield’s exterior coating system was tested for resistance to wind-driven rain using ASTM D6904-03, a standard designed to evaluate whether water can pass through coated masonry when exposed to continuous water spray and air pressure. ASTM describes the test conditions as equivalent to approximately 98 mph wind-driven rain.
Rhino Shield passed the wind-driven rain test, with no water penetration reported under the tested conditions. The test was conducted by KTA, and the result is included in Rhino Shield of Georgia’s published testing data. For Georgia homeowners, this testing provides measurable evidence of the coating’s ability to help resist exterior moisture during heavy rain, thunderstorms, and wind-driven weather.

Important: ASTM D5590 measures fungal resistance under controlled laboratory conditions. Real-world growth can still vary based on moisture, temperature, substrate condition, shade, and maintenance.
How Strongly Does Rhino Shield Adhere to Exterior Surfaces?
Rhino Shield has been tested for adhesion strength to measure how securely the coating bonds to common exterior surfaces. Testing reported 567 psi adhesion on wood and 533 psi on concrete, demonstrating a strong bond to properly prepared substrates. The concrete adhesion result is identified in Rhino Shield’s internal testing data as 533 psi from DRM testing.
Test Summary:
- Wood: 567 psi
- Concrete: 533 psi
- Purpose: Measures coating-to-surface bond strength
- Result: Strong adhesion on both tested substrates
- Testing Data: View additional Rhino Shield Georgia testing results
Why Does Adhesion Matter for Georgia Homes?
Strong adhesion helps the coating remain bonded as exterior surfaces are exposed to heat, humidity, rain, and seasonal temperature changes. When combined with proper surface preparation, strong adhesion can help reduce the risk of peeling and premature coating failure, supporting longer-term durability and lower maintenance needs.

Important: Adhesion results reflect tested substrates and conditions. Real-world performance also depends on the condition of the surface, repairs, preparation, and proper application.
What Does Rhino Shield’s Class A Fire Rating Mean?
Rhino Shield was tested under ASTM E84, which evaluates the comparative surface-burning behavior of building materials by measuring flame spread and smoke development. Rhino Shield achieved a Class A rating, with a Flame Spread Index of 5 and a Smoke-Developed Index of 0 under the tested conditions. The testing data identifies Commercial Testing Company as the testing organization. Learn about ASTM E84
Test Summary:
- Test Standard: ASTM E84-21a
- Fire Classification: Class A
- Flame Spread Index: 5
- Smoke-Developed Index: 0
- Purpose: Measures surface flame spread and smoke development
- Testing Organization: Commercial Testing Company
- Testing Data: View Rhino Shield Georgia testing results
What Does This Mean for Georgia Homes?
A Class A rating indicates low flame-spread performance under ASTM E84 test conditions. For Georgia homeowners—particularly those in wooded, rural, or heavily vegetated areas—this provides an additional fire-performance characteristic alongside Rhino Shield’s other exterior protection benefits.
Homeowners can also explore Rhino Shield’s broader exterior coating benefits.
Testing Note: ASTM E84 measures comparative surface-burning characteristics. A Class A rating does not mean the coating is fireproof or that the underlying wall assembly is noncombustible; ASTM specifically notes that the test should not be used by itself to classify a material as noncombustible.
How Can Rhino Shield Help Save Money Over Time?
Rhino Shield has been tested for solar reflectance and thermal emittance to measure how its exterior coating interacts with solar energy. Solar reflectance measures how much incoming sunlight is reflected rather than absorbed, while thermal emittance measures how effectively a surface releases absorbed heat. These measurements are commonly used to evaluate the thermal performance of exterior materials. ASTM C1549 covers solar reflectance testing, while ASTM C1371 measures thermal emittance.
Test Summary
- Matte Finish Solar Reflectance: 83.7%
- Satin Finish Solar Reflectance: 85.2%
- Thermal Emittance: 0.90 for both finishes
- Purpose: Measures solar reflection and the release of absorbed heat
- Testing Data: Review additional Rhino Shield Georgia testing results
What Does This Mean for Georgia Homes?
Georgia homes experience prolonged sun exposure and high summer temperatures. A coating with high solar reflectance can help reduce the amount of solar energy absorbed by the exterior surface, while high thermal emittance helps the surface release absorbed heat. Together, these properties may help reduce exterior surface temperatures and cooling demand, although actual household energy savings depend on insulation, HVAC efficiency, exterior color, orientation, and other building conditions. ASTM notes that solar reflectance and thermal emittance are important factors in determining surface temperature.

Testing Note: Solar reflectance and thermal emittance results describe the coating’s tested surface properties. Actual energy savings will vary based on the home’s insulation, HVAC system, exterior color, orientation, and other building conditions.
Rhino Shield Testing FAQs for
Georgia Homeowners
What do Rhino Shield’s elongation test results mean for Georgia homes?
Elongation measures how far a coating can stretch before breaking. Rhino Shield testing reported 538% elongation for the white base and 550% for the deep base, demonstrating substantial flexibility under tested conditions. This flexibility is relevant in Georgia, where exterior materials expand and contract through hot summers, cooler winters, and daily temperature changes. ASTM D2370 is used to evaluate tensile properties, including elongation, of organic coating films.
Why is vapor permeance important for homes in Georgia’s humid climate?
Vapor permeance measures how readily water vapor can pass through a coating. Rhino Shield recorded 15.1 US perms under ASTM D1653 testing, indicating that the coating allows water vapor transmission rather than functioning as a completely impermeable barrier. That characteristic is particularly relevant in Georgia’s humid climate, where moisture management can affect wood and masonry exteriors. Learn more in Rhino Shield Georgia’s Testing Results, or review how ASTM D1653 evaluates water-vapor transmission through coatings.
How does salt-spray testing relate to homes in coastal Georgia?
Rhino Shield was evaluated using ASTM B117 salt-spray testing and received a result of 10 with no blistering in its published testing chart. Salt exposure is especially relevant for exterior materials in Savannah, Brunswick, St. Simons Island, and other coastal Georgia communities. ASTM B117 creates a controlled salt-fog environment for evaluating relative corrosion resistance, although ASTM notes that the test alone should not be treated as a direct prediction of natural outdoor service life. Explore the Georgia areas Rhino Shield serves.
What does Rhino Shield adhesion testing show on wood and concrete?
Rhino Shield’s published testing reports 567 psi adhesion on wood and 533 psi on concrete using ASTM D4541 testing. Adhesion testing measures the force required to pull a coating from its substrate, providing evidence of how strongly the coating bonds under the specific test conditions. Strong bonding is important for Georgia exteriors exposed to rain, humidity, heat, and changing temperatures. ASTM D4541 explains the pull-off adhesion test method in greater detail.
What does Solar Reflectance Index mean for homes in Georgia?
Solar Reflectance Index, or SRI, combines solar reflectance and thermal emittance to describe how a surface responds to solar energy. Rhino Shield’s published results report an SRI of 105.3 for matte and 107.4 for satin finishes. For homes exposed to Georgia’s long, sunny summers, solar performance can help reduce exterior surface heat absorption, although it does not guarantee a specific reduction in household energy costs. ASTM E1980 explains how SRI is calculated.
Which Rhino Shield tests are most relevant in different parts of Georgia?
Different performance characteristics may become more relevant depending on where a home is located. Metro Atlanta and Central Georgia homeowners may place greater emphasis on solar performance, humidity resistance, and flexibility; North Georgia homes experience greater seasonal temperature variation; and Savannah and coastal Georgia properties also face elevated humidity, rainfall, and salt exposure. Rhino Shield’s testing covers these characteristics separately so homeowners can evaluate the data most relevant to their location. View Rhino Shield’s Georgia service areas and independent testing reports.
Can laboratory testing predict exactly how Rhino Shield will perform on every Georgia home?
No. ASTM testing evaluates specific coating characteristics under controlled and defined conditions, making the results useful for comparing measurable performance but not for predicting the exact lifespan or performance of every installation. Real-world results can also be affected by the substrate, preparation, application, exposure, moisture, and local environment. ASTM itself notes limitations on extrapolating certain laboratory results directly to natural environments.
Why does surface preparation matter even when a coating has strong adhesion test results?
Laboratory adhesion results measure the coating under controlled test conditions; performance on an actual home also depends on the condition and preparation of the underlying surface. Rhino Shield Georgia’s 11-step installation processincludes inspection, cleaning, repairs, scraping, caulking, and priming before the finish coat is applied. Proper preparation helps create the clean, stable substrate needed for the coating to bond as intended.
