In my recently finished barndominium (in far northeast Texas, a.k.a. Texoma) I asked for concrete floors to be ground, stained, polished, and sealed. Builders did 3 out of 4 and I wasn't savvy enough to understand since they said it was all done and the floors looked good...sigh. So walls are painted and trim (baseboards) is in.

So...I guess I need to understand a few things:

1) What are pros/cons of not sealing the floor? I am pretty sure it is all "con" but I am trying to get moved in, and this situation just became apparent.

2) My research tells me I have two basic choices...a penetrating sealer and an epoxy top coat. Is one or the other specifically better given the situation?

3) If I do decide to hire a contractor to do this, I am petrified about how to not get scammed, which includes a well-intentioned person that doesn't understand he doesn't know what he is doing but talks a good game. Basically I am asking how do I separate the people I want to do this from the people I should avoid.…
