“Hotcake” Wet Film Thickness Gauge

Makes Measurements On Slightly Curved Or Irregular Surfaces. Custom Hot Cake Gauges Available. Call for quote based on quantity and color

Meets ASTM D 4414 Standard Practice For Measurement of Wet Film Thickness of Paints by Notched Gauges.

Hotcake Gauge The “Hotcake” Wet Film Thickness Gauge is so called because it is round and flat. It is an inexpensive, precision made gauge designed for on-the-job measurements of the wet film thickness of applied paints. The gauge is versatile as it can measure with a relatively small footprint, wet paints on objects of practically any size and shape.

Features

top
The “Hotcake” gauge can be used to measure the wet film thickness on small as well as large areas of most any size object. Examples: In Use
  • Areas measuring only 3/8" x 1/8"
  • Inside and outside of pipes & ducts.
  • Thin edges & corner areas of I-beams.
  • Simple convex and concave shaped objects.
  • On flat surfaces
 
The “Hotcake” gauge is particularly suitable to control film thicknesses of industrial and safety coatings. There are many examples such as:
  • Aboard ships
  • Aircraft
  • Structural steel
  • Auto bodies & parts
  • Underwater surfaces
  • Above ground gas tanks
  • Railway gas tanks
  • Wood & metal furniture
  • Highway & airfield marking
  • Flammable surfaces

Principle

top

Paint failures can start anywhere, but most frequently occur in corners and edges where the paint film is either too thin or too thick. When the paint film is too thin, coverage is poor, and loss of hiding and essential protective characteristics are the result. When the paint film is too thick it tends to sag and crack, defacing the film and causing premature paint failure. Overall estimates of film thicknesses are readily made, but are often inaccurate. Such errors can result in waste of time, money, and materials, as the job has to be done over. However, the wet film thickness can readily be measured with the “HOTCAKE” gauge ( Fig.1). Such measurements are important to check the rate of paint application, thereby controlling the ultimate film thickness, and assuring a proper paint job. This gauge in all likelihood will pay for itself on just one job. The price of the gauge is nominal.

 

Characteristics

top
The “Hotcake” gauge consists of a circular aluminum disc with spaced calibrated notches, and recessed flat faces below the rim.

The hole in the center allows the thumb and index finger to hold the gauge and roll it over easily across the wet paint film to be measured.

The outer rim of the disc is completely wetted, while the inner flats, at depths from 1 - 100 mils (.001" - .100") are only wetted according to the thickness of the wet paint film.

Operation

top
Roll the “Hotcake” gauge across the surface in a perpendicular position to wet the numbered faces below the surface of the paint film. After rolling the gauge (or slightly rocking when areas are small) inspect the notched faces. The wet film thickness lies between the highest non-wetted and wetted faces.

 

Maintenance

top
The “Hotcake” gauge should be cleaned immediately after use to avoid drying of the paint. Dried paint is more difficult to remove. Brush repeatedly with a stiff brush (tooth brush) using thinner or water depending on whether the paint is oil or water based.

Thin Film Wet Thickness Gauge

High Precision 1/10th to 4 Mil Range (2.5 to 100 Microns)

Complies WITH and exceeds ASTM D4414

Thin Film Gauge
 
  • Calibration is traceable to the U.S. National Institute of Standards and Technology

  • Calibration procedures qualify under ANSI/NCSL Z540-1 or MIL-STD-45662A as applicable & ISO 9000

  • Certificate of Calibration available at additional cost when ordered with gauge.

  • This polished stainless steel Gardco gauge has forty scale divisions from 0.0001” to 4 mils in 1/10 mil increments.

 

 

Operation

top
The Thin Film Gauge consists of a flat, circular 1/16" thick stainless steel disc with forty machined notches around the periphery and below the rim surface.

Roll the gauge across the surface in a perpendicular position to wet the numbered flat surfaces below the surface of the paint film. After rolling the gauge (or slightly rocking it when areas are small) inspect the notched faces. The wet film thickness lies between the highest not-wetted and wetted faces.

When measurements are made on a clear coating, after rotation of the gauge over the wet film, dust talcum powder on the flat faces and then blow it off. Talc will adhere only to the wetted faces.
