The outside lip of the garage floor turned yellow because epoxy is not UV resistant. Direct sunlight anywhere on a epoxy will yellow or discolor over time. By using a UV resistant coating such as a urethane, it will hold up longer to the elements of sunlight. Even a urethane in certain parts of the country will yellow. The photo below is from a home in Florida that had used a urethane clear topcoat. We do not recommend using an epoxy on any exterior surface.
