The measurement method is simple and non-destructive. Measuring Paint Thickness over Surface TextureĪpplication #1: Measuring Total Thickness of a Paint Systemįor those familiar with magnetic coating thickness gages, using ultrasonic coating thickness gages is easy and intuitive.The PosiTector 200 B3 Graphics Capability.Measuring Paint Thickness on a Textured Surface.Using the PosiTector 200 B1 to Measure Total Thickness of the Paint System.PosiTector 200 Drywall Measuring Applications: It also features a graphics mode for detailed analysis of the coating system The PosiTector 200 B3 (Advanced model)* is capable of measuring both TOTAL coating thickness AND up to 3 individual layer thicknesses in a multi-layer system.The PosiTector 200 B1 (Standard model)* is the economical and most common solution for measuring the TOTAL coating system thickness. ![]() Other challenges include a tendency for primer to absorb into the paper membrane of drywall, the effects of paint surface roughness or texturing, the impact of measuring over joint compound, and the potential need to measure individual paint or primer layers. Today, the primary purpose of ultrasonic paint thickness testing is to non-destructively measure the TOTAL thickness of the paint system, typically in the range of 3 to 5 mils (75 –125 μm). ![]() Traditionally a destructive test method is used to determine paint thickness. Fig.1 PosiTector 200 B1 measuring the combined thickness of a single layer of paint and the under layer of primer.ĭrywall is typically painted with 3 layers (one primer and two paint layers).
