Paint drying watcher
Yep, this is a real thing. Just like dog food and skincare products, paint needs to be tested – and one of the factors that have to be assessed is its behavior during the drying stage.
Here is how it’s usually done: the watcher puts a bit of paint onto a surface (could be a wall, could be a piece of cardboard) and uses a stopwatch to measure the drying time. All the while the sample has to be monitored for changes in color, texture, etc. The job is probably a bit boring, but those in the know say it pays really well.
