First you must pressure wash as best as possible. Next you need to acid wash the concrete. Finally you should be able to neutralize the acid with a vinegar and water solution. Let dry. You should prepare the whole floor this way.

yes
The two parts are: epoxy monomer and hardener/catalyst. Upon mixing the hardener/catalyst triggers polymerization of the epoxy monomers and the adhesive sets.
