When it comes to choosing a garage floor coating, there are several types of products that can be used. The best garage floor coating for sealing your garage floor will depend on several factors, including:
- Your budget
- The amount of time you can or want to invest into prep work
- The amount of time you can or want to invest into maintaining the coating
- What you use the garage floor for
- What you need the coating to offer from a performance perspective
There are five types of products that can be used to seal a garage floor:
- Penetrating Sealer
- Acrylic Sealer
- Epoxy Coating
- Urethane Coating
Penetrating Garage Floor Sealers
The two most common types of penetrating concrete sealers used to seal garage floors are water repellent sealers and concrete densifiers. Concrete densifiers are used to increase the strength of the garage floor, while water repellent sealers are used to reduce deterioration caused by water absorption.

Garage Floor Paint
I cringe when I hear that someone wants to use paint for their garage floor. They are very cheap and easy to applying which makes them a popular choice, but they don’t bond well, are hard to maintain, and after a few re-coats will turn your nice garage floor into a rough and clumpy looking disaster. Most articles written on garage floor paint are how to remove them.
For the same amount of effort and a little more cost, you can apply an acrylic sealer to your garage floor.
Acrylic Garage Floor Sealers
Acrylic sealers offer a very hard finish once fully cured and are great sealers to use on garage floors. There are many benefits to using an acrylic sealer, including:
- Acrylic sealers are very easy to apply and require little to no prep work
- Acrylic sealers can be applied in clear or in color options
- Acrylic sealers will protect against dusting, staining, and deterioration
- Acrylic sealers are very easy to maintain and re-coat
Acrylic concrete sealers are great to use if you are looking for a cost effective, easy to apply, long lasting coating for your garage floor. If you have high moisture issues, or use your garage to constantly repair cars, an epoxy or urethane coating may be better.

Epoxy Garage Floor Coatings
When you think of a garage floor coating, you think of an epoxy. They are very popular coatings for garage floors mostly because they are very easy to come by. Epoxy coatings can be purchased at just about any hardware store, and online. They come in clear, color options, and with flake/chip options. There are a few things to consider when thinking about an epoxy coating:
- The surface of the concrete must be acid etched or ground to allow for proper coating adhesion
- The surface of the epoxy coating must be screen sanded before recoating
- Epoxy coatings vary significantly from one manufacturer to the next
When it comes to epoxy coatings, they vary significantly from one manufacturer to the next. Some epoxies are designed to reduce moisture, while others will peel if moisture is present. Some epoxies can be colored, others can only be applied in clear. Some epoxy coatings can be applied as is, while other epoxy coatings require a top coat. Everything from the solids content to the resins are very different.

Urethane Garage Floor Coatings
There are a couple of different types of urethane coatings that can be used on garage floors. The two most common categories are polyaspartic and aliphatic. There are minimal differences with durability.
- Aliphatic urethanes have a slower cure time which gives you more time for application. This also allows for a nice, constant flat finish. Polyaspartics often result in orange-peel type surface ripples because of their overly-fast cure times.
- Aliphatic urethanes are more resistant to chemicals.
Urethane coatings require a lot of surface preparation. The surface must be ground with a diamond grinder or a shot blaster. It must be clean and free of all materials, and completely dry during the time of application. Urethane coatings can be applied directly to the concrete surface, or to epoxy primer coatings within the recoat window.
Urethane coatings are long lasting, high performing coatings. They are used for industrial and residential applications, and can be applied in clear or color options.
