Yes. Because a chemical bond is no longer possible because the epoxy coating has dried, a mechanical bond is required. This merely means that the cured epoxy must be lightly sanded before applying the next layer: the first coat should have a matt, nearly white finish.
You should always check for compatibility of the products you are using, but epoxy coating can and probably should be top-coated with a polyurethane product.
Epoxies are not UV stable and will yellow over time exposed to sunlight. Additionally, epoxy is a hard material that scratches easily. A polyurethane top-coat is more difficult to scratch and is UV stable. It will also provide a very rich deep shine to your coating.
NO. Nothing sticks to poly or gloss.
----------
The above statement is totally false !!! You can paint over and stick all sorts of other applications to polyurethane with the proper preparation.
You are wrong. With the proper preparation [scuff with 60 or 40 grit], polyester and epoxy resins will stick!
Yes, you can paint epoxy over polyurethane.
Yes.

Epoxy floors are very strong and durable, a well installed epoxy floor can last up to 25 years. They are also scratch resistant and are ideal for areas with heavy traffic
compact discs are made of polycarbonate plastic followed by a thin layer of aluminum coating over the polycarbonate plastic then finished with a clear protective acrylic coating over the aluminum layer some companies use silver or gold instead of the aluminum layer
Powder coating is the application of powder paint on a surface for a variety of reasons. The powder used in powder coating comes in many different colors and types depending on the surface that must be coated, and reasons for coating. The most popular colors for powder coating is black and white, but a variety of other colors are available. Power coating can be accomplished through different methods using two different powders; they are thermosets and thermoplastics. Both methods use polymers, which range from polyester to acrylics to urethane chains. The different polymers differ because of functional groups present on the chemical structure of each polymer. Through different application processes, one can powder coat a surface and create a surface that is more durable and scratch resistant. The two powders coating, themosets and thermoplastics, differ in how they can applied to the surface. The thermoplastic powder becomes plastic when temperatures are increased, due to formation of strong nonpolar bonds between the polymer molecules. The thermosetting powder hardens after heating because the polymers in this powder form strong chemical linkages. To apply these two different types of powders, both professionals and individuals use a powder-coating gun. These powder guns, like the powders themselves, are manufactured by different companies and can be purchased at different home improvement stores. The gun used and the temperature used to apply the powder will depend on the surface that is being coated. The coating gun functions to electrostatically spray the surface and under the heat, the polymers in the powder link together. The function of the gun depends on friction, ionization and charge on molecules. The chemical linkage of the molecules, at a micro level, leads to the formation of firm and rigid material. Additionally, depending on the material being coated, different sizes of powder polymer might be used. Powder coating is used on a variety of surfaces for a variety of reasons. One might apply powder coating to walls at home to prevent damage through scratches or to prevent cracking and peeling in the wall. One might apply powder coating to metal surfaces, such as on a car or bike, to prevent rust formation that develops after a certain period of time. Power coating has also been used on fences, frames of different items and structures, and grills. Therefore, the powder coating serves as a layer of protection against any damage to the surface. In fact, it has been established that the chemical linkages that form from powder coating are stronger than regular paint. It has been recommended by professionals that powder coating can be used to protect surfaces better than regular liquid paint. Additionally, experts have continuously noted that powder coating is environmentally friendly because no dangerous chemicals are produced or used in the process. If one desires to remove power coating from a surface that has been powder coated, one can use a chemical called methylene chloride as a solvent. In addition to its environmentally friendly qualities, powder that is over sprayed and unused can be recycled for future use and is not discarded.
you can't as such make them nickel free but it does help if you put a coating if clear nail polish over the area that is in contact with your skin.
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.

As long as none of the paint is flaking, you can.
Usually when you're planning on going over it with additional concrete or cement, or in preparation for an epoxy or waterproofing coating.
no
The Sharpie will eventually wash off the epoxy. The only way to keep any drawn image on it is to sand it down and do it or possibly draw with your Sharpie and apply a couple coats of epoxy clear coat over it.
Yes. Seaforce 90 is a self-polishing antifoul (it is however relatively hard in comparison to Micron Extra) and so it compatible with other self-polishing antifouling. Give the existing antifoul a wet sand and apply Micron Extra. If you go back to the epoxy, or there are areas where the current antifoul is suspect then apply a sealer coat of International Primicon.
I am guessing this is on the floor. This is probably a two component carbon bond coating. This means it is chemical resistant to even ketones. To recoat, you must use another epoxy or urethane mixture. To prepare the surface, it must be wet sanded with at least 220 grit water paper. After a good sanding, the surface must be cleaned with some sorta tack cloth. If you use a waxed based tack, do not press hard. This will cause transfere of the bees wax to the surface and cause poor adhesion. Anyway, get the surface clean as possible. Make sure the humidity is below 50% before coating the area. If you try to coat with humidity aboue 50%, you may get bubbles in your coating. They are caused by the coating trying to cure quicker than the moisture can escape. I hope you can use this information.
Yes, it can.
You can definitely use latex paint over epoxy. In fact, it is recommended to use latex over epoxy by the paint manufacturers, rather than using epoxy over epoxy. The latex adheres better and if you then want to use epoxy next time you paint, you have a nice coat of latex between the layers. If you use epoxy over epoxy, often the paint will just peel off in layers once some time passes (and sometimes right away).
Yes, it is always necessary when carrying out repairs . The area surrounding the repair is sanded , and the primer patch extends outside the repair onto this "feathered" area. Both epoxy and urethane based primers are suitable.
No, since glaze is a process that requires it to be fired. There are professionals who use an epoxy on glazed ceramic to change colors if that is what you want to achieve.
