The two-cup mixing method helps ensure that epoxy resin and hardener are blended thoroughly before application. First, combine Part A and Part B in one clean mixing container. Mix thoroughly for 2 to 3 minutes, scraping the sides and bottom of the container as you stir.

Next, pour the mixed epoxy into a second clean container and mix again for another 2 to 3 minutes before pouring or applying it.

This method helps reduce the chance of unmixed resin or hardener remaining in pockets along the bottom or sidewalls of the first container. This is especially important with thicker epoxy systems, where unmixed material can be harder to incorporate completely and may lead to soft spots or incomplete curing.
