Understanding Dry Film Thickness Measurement with the Landtek CM-8820
Dry Film Thickness (DFT) measurement is one of the most important quality control procedures in painting, powder coating, steel fabrication, and industrial manufacturing. Measuring the thickness of a fully cured coating helps ensure adequate corrosion protection, coating durability, and compliance with project or customer specifications.
The Landtek CM-8820 Coating Thickness Meter is designed to accurately measure dry, non-magnetic coatings on ferrous (steel and iron) substrates. It is widely used by manufacturers, coating contractors, inspectors, and quality control professionals throughout Malaysia.
What is Dry Film Thickness (DFT)?
Dry Film Thickness (DFT) refers to the thickness of a coating after it has completely dried or cured. Unlike Wet Film Thickness (WFT), which is measured immediately after paint application, DFT represents the final protective coating remaining on the surface.
Measuring DFT helps determine whether the coating provides the required level of protection while avoiding excessive paint usage.
Why is DFT Measurement Important?
Proper Dry Film Thickness ensures that protective coatings perform as intended.
A coating that is too thin may not provide sufficient protection against corrosion, chemicals, moisture, or weather exposure.
A coating that is too thick may increase material costs and cause cracking, peeling, blistering, or poor adhesion.
Regular DFT inspection helps maintain product quality and ensures compliance with project specifications.
Applications of Dry Film Thickness Measurement
The Landtek CM-8820 is commonly used for measuring DFT on:

How to Measure Dry Film Thickness
Step 1 – Allow the Coating to Cure
Ensure the paint or powder coating has completely cured before taking measurements.
Step 2 – Calibrate the Instrument
Calibrate the Landtek CM-8820 using the supplied calibration accessories according to the user manual.
Step 3 – Prepare the Surface
Remove dust, grease, moisture, and loose contaminants from the inspection area.
Step 4 – Measure Multiple Points
Take readings at several locations to identify coating consistency across the entire workpiece.
Step 5 – Compare with Project Requirements
Compare the measured values with customer specifications or internal quality standards before approving the product.

Frequently Asked Questions (FAQ)
What is the difference between Wet Film Thickness and Dry Film Thickness?
Wet Film Thickness (WFT) is measured immediately after coating application, while Dry Film Thickness (DFT) is measured after the coating has fully cured.
Can the Landtek CM-8820 measure Dry Film Thickness?
Yes. The CM-8820 is specifically designed to measure dry non-magnetic coatings on steel and iron substrates.
Can it measure powder coating?
Yes. It accurately measures cured powder coating thickness.
Why should multiple measurements be taken?
Coating thickness may vary across different areas. Multiple readings provide a more representative average and improve inspection reliability.
Who should use the CM-8820?
The instrument is suitable for quality inspectors, engineers, coating contractors, manufacturers, maintenance teams, and steel fabricators.
