Jim Godward said:OK, the easy answer is YES to both. In some areas I removed the old in others I cleaned it and covered it with the EternaBond. Where I removed the old, it was easier to make sure the EternaBond was well adhered. In the other areas where the old was still there, I had to make sure there was a good margin between the edge of the old and the new edge. The recommendation as I recall was for at least 1/2" of the EternaBond beyond the old. That is why in a few cases I did additional removal in order to get that margin.
