Help With Trap Door on Chimney

Hello, took out my 4 inch old gas stove vent in my chimney and everything looks good, no cracks in the mortar at all. Bought a new chimney cap at Lowe's and all ready to go. I opted to open the clean out on the bottom of the chimney and it just fell out. I am assuming that is a problem. It is a piece of metal, pretty thick and I am going to clean it up and paint it before I put it back, but I have two questions:

1. What should I paint it with? Can I just use a rust-o-leum product or should I go with something for a high temperature since it is part of the chimney, or since it is just a trap?

2. How or What should I use to put it back in place? I am assuming some sort of furance cement. Any suggestions on how to place it until it "sets." Since it isn't screwed in at all.

Thanks again everyone!

Dan

Any paint, standard portland or ready mixed... Just lean something against it so it doesn't move until the cement sets. There's no heat there at all so nothing special needed.

What you may want to do is chip away any cement that is on the chimney in that area so you can get thick enough layer of crete.
