There is a possibility of putting vinyl flooring in the shed thanks to a relative in the flooring biz that can get me the flooring for free so we put down a layer of ?? thick underlayment. Why add vinyl flooring to a shed?? If its free and if we would care to butcher animals inside, it will be easier to clean the floor without having to paint the floor to protect it from blood, etc. Any spills, drips, etc will be easier to clean up and that way we don?t have to paint the floor to protect it.
Also, we got the underlayment from Home Depot from their cull wood area (purple wood) which is 70% off due to edge damage of the 4 x 8 sheets but since the inside of the shed is 11 ft 5? x 11 ft 5?, trimming the damaged edges of 4 x 8 sheets makes it a good option.
Then we started adding shelving around the west wall (more will be added to other walls). Since the shed has 8 foot high walls a 13 inch deep shelf was added and a 9 inch deep shelf below that. This will save floor space.
