Sealing The Floor Of Your Garage

Whether you have just started shopping around for garage doors or are currently in the process of repairing the parts that have broken down, it’s time to consider how to seal the floor of your garage. There are many positives to doing this such as easier to clean, stays cleaner and it looks cleaner. Most garages are commonly poured with concrete and over time the wear and tear of vehicles and foot traffic can do damage to it. For many years it was thought that concrete is the only material suitable for garage door floors due to the durability. Over time though, innovations have been invented and now there are better materials that should be used for the floor of your garage. So properly upgrading and sealing your garage door will make it look better but it will make the entire home seem nicer as well.

This may seem daunting, but I promise you, it’s not as hard as it seems to seal up your garage door floor.

Types of Garage Floor Sealers

To be successful in any job you need the right supplies and material. There are multiple types of floor sealants used on garage floors and can be classified into two different categories: penetrating and topical.

Topical Sealers

Topical sealers actually stick to the top of the garage floors concrete but it adds a much needed protective layer. They are different from penetrating sealers because they adhere to the concrete surface and do not bond with upper layers which penetrating sealers are designed to do.

Acrylic Sealers

Acrylic sealers are the most affordable type of garage floor sealer. These sealers can be applied with either a roller or a sprayer. It’s recommended that you use two coats of acrylic sealer, and allow 24 hours for it to settle in before driving over it.


Epoxy is the next most common topical sealant used in garages after acrylic. It’s thicker and more expensive than acrylic but if does form a stronger bond. Most people prefer to use epoxy floor sealer with slip-resistant coatings such as metal chips or granite.


Polyurethane is an uncommon topical sealant, probably due to it’s higher price tag and more involved application process. A primer must be applied to the floor before applying this sealer. The main advantage of polyurethane sealers is that they are more durable than other topical sealers and inherently protect against UV radiation.

The other main type of sealers is known as “penetrating sealers” which differ from topical sealers in the sense that they actually bond with the available lime in the upper layer of concrete and form calcium silicate.

Prepare Your Garage Floor

The first thing to do is prep the garage door floor. You can do this by cleaning out any junk and dirt with a washer or sprayer. This helps ensure the best bond between the concrete and the sealer you have chosen. Here are some guidelines:

  • Avoid temps below 50 degrees as they will impede your sealers ability to bond to the concrete.
  • The floor needs to be as clean as possible, so give a thorough cleaning and sweeping.
  • Apply an etchant, which is a type of acid that helps remove any chemicals that remain after the sweeping and pressure washing.

Applying and Maintaining Your Sealer

Now it’s time to apply your sealer. It’s actually a simple process. You will most likely use a pump sprayer or some type of paint roller. Be sure to add a thick layer of your sealant and be sure to give it plenty of time to dry out. The advice is to add 10-20% more time than the manufacturer suggests. The more time it has to bond with the concrete, the better.

To make sure it lasts as long as possible, there are some basic maintenance steps you should take. Clean immediately any oil spills, gas or grease. The less time these spills have to bond the better. That’s really all there is to it! A well-sealed garage will provide years of improved durability and aesthetic value to your garage.
