Will this urethane bond over the Dritac 7700 adhesive? I have an area where I have feathered out the 7700 and would like to use urethane for the next roll of 3/8" rubber.

We don't recommend using the two different types of glue over each other. If you need to use one over the other, we would recommend removing the glue first applied and then placing the new glue down.
