If your old epoxy is good then you can apply over it, but there are many facts to consider before applying over existing epoxy coating.
Go with the Epoxy coating. Epoxy is well-known for being a top-notch protector any time it is used as a coating.
Epoxy-polyester powder coating is a hybrid of epoxy and polyester powder coating, and galvanised is coating thickness for steel bars and components is between 3 and 4 mils.
Epoxy floor coating systems are made up of two distinct elements: an epoxy resin and a polyamine hardener.
Epoxy and polyurethane can be mixed. An epoxy and polyurethane coating system is often used in the marine industry to protect against the weather.
You must remove the old epoxy coating before pouring the new floor, for otherwise there will be no bonding. If the epoxy coating is thin (e.g, paint) then it may be possible to remove it by hand sanding. If it is a thick coating, then sandblasting is probably the best method. In either case, appropriate dustmasks and other safety precautions are essential. Good luck
Epoxy floor coating gives one's floor an appealing shine. However, it also has technical benefits. This coating is a strong adhesive which is waterproof and oil-proof.
No, Seal-Krete Epoxy-Seal is an acrylic-epoxy blend. By mixing 2 unlike resins (patio paint and Epoxy-Seal) the hard Epoxy-Seal acrylic-epoxy resins would become weak resulting in a coating failure.

Epoxy floor coating is thicker than other coatings and more durable. It's chemical resistant, resistant to scratches, and resists fading. The following is a good site to read about epoxy coating: http://www.epoxy-coat.com/why_use_epoxycoat.php
Epoxy coating is most commonly used to protect steel pipes in pipeline production, concrete reinforcement bars and a wide variety of piping connections and valves to protect them from corrosion.
