- The applicator in this video is injecting with polyurethane packaged in an Emecole Metro universal cartridge.
- Whether injecting a crack with polyurethane or epoxy, the step-by-step process is nearly the same.
- The video mentions flushing the crack with water prior to injection. This step should not be done when injecting with epoxy. The added water inside the crack may affect the injected epoxy, where as water serves as a catalyst for injected polyurethane.
- Near the end of the video, the narrator references how “the resin expands into a foam.” The foaming characteristic only applies when injecting with polyurethane, as epoxy cures to a hardened material as opposed to foaming.
