Actually, the surface gravity on Mercury is much heavier than Luna; almost identical to Mars, in fact: 37.8% of Earth's gravity on Mercury, as opposed to 38.03% on Mars. Luna is in the next class down, at 16.56%.

And as for the daytime temperature on Mercury, it isn't just that it's 'higher' than on Luna it's a Hell of a lot higher: 836F for Mercury (which is hot enough to melt Lithium, Tin, Cadmium, Lead, and Zinc), as opposed to a mere 224F on Luna.

Worse yet, the nighttime temperature on Mercury is actually colder than Luna's -298F on Mercury, -243F on Luna which gives Mercury the greatest temperature range in the entire solar system, and such radical changes in temperature would wreak havoc on any machinery on the surface.

And then there's the deadly daytime radiation levels.

Nope Mercury is not a friendly place for human colonization, except on a very limited scientific scale. The only safe place you could build on it is inside a crater near one of the poles, where you'd be protected from the Sun and you'd only be able to venture out of your crater base at night.
