Swatch Wipe
NACE Level 3 CIP Barry McCoy from Surface Technologies Corp. contributed this “Swatch” test as it is consistent from project-to-project and easily taught.
Make a “swatch” or wad of the dry cloth. Tape the tail to make a handle.
Lightly wipe the swatch once over the surface. This path was about 3 inches (7.5 cm)
Be consistent in type of cloth, path length, and swipe up or down or sideways.
This results in a wiping motion without pressure points from individual fingers.
Example of Swatch- Light Flash Rust
Comparison of two types of clothes. Cloth can make a difference. Be consistent in your selection of cloth.
Swatch Test with Two different cloths in another field case of “Heavy” Flash Rust.
In this comparison, we got two different results.
