I mixed up my deck mud, and protected my weep holes, now it was time to actually put down the floor.   I drew a couple guide lines on the walls, and adjusted the drain to the proper height so that I would get the specified 1/4″ per foot slope.  Then I dumped about half of the deck mud into the shower, and got to work, spreading it out and compacting it (using the top of a small sledge hammer) after I got the first half roughly down, I reinforced it with a piece of galvanized metal lathe, and dumped out the rest of the deck mud on top.  The second layer is much more work than the first, since the slope has to be close to perfect so that water actually goes down the drain, as this will be the layer that the tile goes on.  So after an hour or so of leveling, compacting, checking, and leveling I was finally happy with the end result.  I had my wife check and make sure that she couldn’t find any spots where the floor wasn’t sloped towards the drain, and after fixing the one spot she found, I was finished, with a very exhausted arm, after stamping down the mortar for an hour or two.  Happily after letting it dry overnight I was very happy with the result.
