Unhappy Painted floor problem

I mistakenly painted semi-gloss over high-gloss paint on my porch floor and now moving things causes the top layer to peel.
I am thinking of using my belt sander to remove as much paint as possible - any simpler ideas would be appreciated.

If the original paint was not removed or sufficiently scuffed up to allow the new paint to adhere then the top layer will simply peel off. No easy way to remove and sanding is probably the best way to remove and prep for the new material.

Use a good primer!

Semi-gloss over gloss in itself isn't normally a problem. I suspect you used a latex semi-gloss over an oil base gloss - that is a problem. Latex paints don't generally adhere well over oil base enamels. If that is the case, you need to remove as much latex as feasible [either mechanically or chemically] and either use a solvent based primer prior to using latex or go back to oil base.
