This is what the kitchen floor looks like after it has been "mudded over" (a completely technical term for covering the floor with concrete-like mud). It basically provides a hard undersurface free from the defects of the 30 year old floor. It was poured in about 3 different layers, each one oozing out further than the previous one.

This is a shot of the dining room area, also quite completely mudded. This was also done in about 3 days, as was the kitchen. The mud does not take very long to prepare (one part water, 5 parts "mud dirt") and it basically evens itself out over the floor.
