The test sample is chilled for several days in a freezer. The cold sample is then subjected to a very slow bending, with one board secured in a vise. We carefully observe which sample fractures first, and by noting how many degrees of flex each sample endured, we can compare samples from other tests. Using different types of primers helps us determine whether one primer provides a better grip for a given caulk. Applying samples to the end grain, as opposed to the sides of the boards, will prevent the boards from splitting during the bending test.
