blacktop flooring?

[trushelrl]

Hi guys - I have a small garage (about 14' x 20') with a blacktop driveway. I would like to epoxy my floors next summer, but I think that my floors are blacktop. It appears that there were concrete floors in it, but the concrete in the garage was blacktopped over once the driveway was finished. It may very well be some other substrate as well (it looks like a cross between blacktop and concrete if that makes any sense).
There are also filled spots with a tar-type substance. I know that this tar-type substance will need to come out before any painting...would concrete repair work for this?
Does anybody know any methods to test to see what my floor is? If it is blacktop, can I epoxy over this, or will it secrete too much oil for the epoxy to stick? Any help is appreciated!

Thanks,

Rick Trushel

Blacktop/asphalt is oil based. Pour gasoline on it and it will degrade to rocks if enough is used.

I'd say no-way to epoxy on it.

Can you see aggregate/rocks in it? Possibly (hopefully) it is black asphalt coating over concrete. Still dont know if that can be rectified or not.

Sorry guys - I am unable to post any pics. Upon a little further inspection, I believe that it is just blacktop. The surface is very dirty, and has sort of a gray-brown tint until it was powerwashed. Now it is definitly a darker gray. The surface looks like it is unfinished and has a very rough texture.
I am going to cut a small peice out to expariment with. I figure I'll take a peice of the garage flooring and a small peice of my driveway and soak them each in a small container with gasoline in it. If they behave in the same manner, they are the same substance and them painting will be a no-goand I guess I'll have to live with ugly floors for now.

Thanks,
Rick
