Not sure what brand you're considering, but I put some Armstrong and here's what their installation manual says:
"9. Curing, Sealing, Hardening or Parting Compounds
“Curing compounds leave a film that can interfere with the adhesion of
other materials to the treated surface; … Their use should be avoided on
surfaces that will later be covered with resilient floor coverings, … Where
applicable, a letter of compatibility should be issued prior to the use of a
curing compound on a floor receiving a subsequent finish.” (Quote from
American Concrete Institute, ACI, publication 302.1R-96, “Guide for
Concrete Floor and Slab Construction,” page 50.) Any letter of compatibility
must come from the manufacturer of the compound.
When curing, sealing, hardening or parting compounds have been used, the
following general statements can be made:
a. If they contain soap, wax, oil or silicone, they must be removed before a
resilient floor can be installed.
They can be removed by using a terrazzo or concrete grinder, by sanding
with a drum sander or by using a polishing machine equipped with a
heavy-duty wire brush.
b. There are many materials that do not contain soap, wax, oil or silicone
and are advertised as being compatible with resilient flooring adhesives.
No specific statement can be made regarding their use or need for
removal. Conduct bond tests to determine the need for removal. If after
72 hours the bond fails, the compound must be removed."
My summary is that it would probably be fine, you might be able to check with the manufacturer of your epoxy product about it's compatability. If not, maybe an adhesion test before doing the whole thing.
