Concrete Sealer, before or after metal building install?

First time post here. A lot of useful information on this site. I am in the Process of Building a 30X40X13 tube style metal building. It will asked have a 12X40 lean to. I have pretty much decided on the Ghostshield densifier and sealer. My question to you all is should I put the densifier/ sealer down before the building is installed? Concrete is roughly two weeks old right now I’m still about a month out on the building.

Always do the floor last. In our experience the contractors damage the surface no matter how careful they are. Gostshield though being a penetrating product most likely wouldn't show any damage, but in our opinion wait until the building is completed.

I guess that’s why I was wondering, since the sealer penetrates and doesn’t change the look of the concrete why wait till the building is already up?

Typically, concrete should cure for at least 6 months before you seal or paint it. Some sources say a year.
