Yes, expensive epoxy floor paint would be a further improvement, but the multi-coats of sealer would have to be completely acid?removed after the concrete cures, with yet another delay in area use.

Think it best to use and enjoy the nice, new deck, maybe wipe thy feet and minimize splats, smears and spills.

Bet the next project will be a concrete floor in bay 1.
Heating...what's the latest?
