If you are looking for a covering for your garage floor in order to make it safer or just to improve the aesthetics of the garage you have three main choices.  You can use some sort of mat system, you can apply a standard floor paint or you can choose a long term solution and apply an epoxy coating.  By far, if you plan to stay in your current residence for an extended period of time the best garage floor covering is going to be the epoxy because it lasts for so long.

If you plan to move relatively soon, or you are just renting, then floor mats would be a good choice.  There are two options here for you to think about.  First, you can buy a roll out mat that does just what the name implies.  You buy the matting in a roll which is usually 10’ wide.  You roll it out and if your garage is wider than ten feet, which most are, you can tape two sections together.  The second method involves interlocking squares which seal the floor from any water or fluids.  These are much more expensive but they last a long time and look great.  Both of these style are actually anti-slip mats.

Garage floor paints will last for a while but you usually have to re-apply them every couple of years.  Also, do not use a floor paint unless you apply a non-skid additive on top.  This is spread out after the paint is rolled on and before it starts to dry.  Without this the floor surface becomes like ice when wet.

Although these options work, you are going to be much happier if you bite the bullet and apply a good quality floor epoxy to the concrete in your garage.  These coatings have been known to last for years and even a couple of decades.  By far, the epoxy coating is the best garage floor covering but like the paint you absolutely must apply a non-slip additive to the top surface or your floor will be dangerous when wet.
