Coating your garage floor with epoxy seal paint will provide you with the best clear finish. For a better finish, coat your garage floor multiple times.
There are different ways to seal concrete. One way to seal concrete is to do it while the concrete is drying by applying a sealant with a paint roller. Another way is to use epoxy. Another great way is to use interlocking tile for the garage. Swisstrax has a good durable product that makes a garage looked. I would recommend the tile because it makes the garage look better and it is easy to install.www.swisstrax.com
It is best if you do remove the old paint first.

Your cement or concrete garage floor needs to be maintained properly for it to look good and stay safe to walk on. Spills of paint, oil and other slippery substances should be cleaned up as quickly as possible. Clay cat litter is a good material for soaking up spills. Once you sweep up the cat litter, spray the affected spot down with water and scrub it with a bristled brush. Only concrete cleaning solutions should be used. Pouring bleach, detergents or other chemicals onto garage floors can cause damage to the concrete. Weakened concrete is more likely to crack during the winter's cold temperatures or when you drive a heavy vehicle over the spot. If you are concerned about spills soaking into the concrete, try sealing the surface with an epoxy based coating or a concrete paint. Paint is easily to apply, but won't last as long as epoxy if you park in the garage.
Rustoleum's concrete paint is made from acrylic and can be applied with only one coat. It is hot tire and chemical resistant as well as UV resistant.
