ASTM D6762: Spray Coating Hiding Power Testing Services
ASTM D6762 test method determines the properties of spray coatings by quantitatively detecting the film thickness required for full hiding. The thickness of the film determines the hiding power of the test paint. This method is only applicable to spray-applied coatings, but the concepts can be applied to other application methods as well.

What Is ASTM D6762 Spray Coating Hiding Power?
ASTM D6762 is a standard test method for visually assessing the hiding power of spray-applied coatings. This test method determines the film thickness required for a paint or coating to conceal a contrasting background pattern.
By evaluating hiding power, this test can predict the coating’s performance, efficiency, durability, and cost-effectiveness. The outcome of this test will provide a clear indication of the coating’s quality and coverage.

Our ASTM D6762 Testing Procedure
Panel Preparation & Spray Application
Patterned panels are prepared, and paint is applied in a wedge-shaped film.
1Drying
The coating film is allowed to dry under standard conditions.
2Visual Inspection & Hiding Point Detection
The film is examined to identify the point where the background is entirely hidden.
3Thickness Measurement
Coating thickness is measured at the hiding point.

ASTM D6762 Spray Coating Hiding Power FAQs
ASTM D6762 determines the film thickness required for a spray-applied paint to achieve complete hiding of the underlying substrate. This thickness is used as the paint's hiding power.
The test coating is spray-applied in a wedge-shaped film over a contrasting pattern. After drying, the coating is visually examined under standardized illumination to identify the point where the underlying pattern is just fully obscured. The corresponding film thickness represents the hiding power.
ASTM D6762 is specifically intended for spray-applied paints and coatings. Although the concepts may apply to other application methods, the standardized test method itself is designed for spray application.
Hiding power indicates how effectively a coating conceals the color, pattern, or substrate beneath it. It is useful for evaluating coating formulation, pigment efficiency, application requirements, and the amount of paint needed to achieve uniform coverage.
ASTM D6762 uses visual evaluation of a spray-applied film, making it closely related to practical coating application. ASTM D2805, in contrast, uses controlled film thickness and photometric measurement and generally provides greater precision.
