Here is the start to a custom marmoleum job I did for Dykeman architecture. This was a very difficult project that I really enjoyed working on. First we removed all of the existing marmoleum. The substrate was then leveled with uzin nc 170 self leveler. In addition to that sections of the substrate still needed more work which we did with ardex feather finish.
After spending quite a bit of time with an architect we came up with a way to recreate an arc using two different points you see in the first two drawings.
