Measuring the Wet Film Thickness of GE Enduris* 3500 Silicone Roof Coating

When applying GE Enduris* 3500 or any other GE silicone coatings, the wet film thickness is important as it dictates whether a coating is covered under any product warranties applicable. Also, it signifies the durability of coating, the thicker, the stronger it will be! GE provides a wet film thickness gauge that is useful for any coating applications with GE Silicones that you may encounter. 

Measuring the wet film thickness is simple. After applying GE silicone coating, either by spraying or after backrolling a squeegee application, gently place the wet film thickness gauge supplied by our distributors onto the coating. Read the reading on the deepest tooth that has coating material on. This is the wet film thickness at the test location. After taking reading, gently wipe the thickness gauge clean with a cloth to prevent silicone material from settling. 

For every project, it is required to take multiple readings, from different spots around the surface to make sure minimum wet film thickness is met in all areas.
