Flex Seal is a special type of sealant that has lots of unique properties. It’s thicker than regular paint and as a result, it can do a great job at sealing surfaces from moisture, air, and water.
Flex Seal is also quite versatile. You can use it on roofs, awnings, and windowsills, amongst others. But can you use Flex Seal on a garage floor? That’s what I’ll be discussing in this article.
Can You Use Flex Seal on a Garage Floor?
Flex Seal can be used on garage floors. It can help with waterproofing the garage floor, repairing cracks, and even weatherizing it for winter.
On a garage floor, Flex Seal is more than capable of sealing moisture, mold, air, and water. It’s very easy to apply Flex Seal because all you need is a brush.
It’s also important to mention that the manufacturer has approved the use of Flex Seal on concrete which is the most common garage floor material.
However, before you apply Flex Seal on a garage floor, there are a few things you need to keep in mind.
Key Factors to Consider Before Using Flex Seal on a Garage Floor
1. It’s a Temporary Solution
The first and most important thing you have to know is that Flex Seal will not last for a long time. Whether you’re using it to seal cracks on a garage floor or seal moisture from passing through, Flex Seal will only serve you for a few months.
2. It Only Works on Small Cracks
Do not use Flex Seal on a garage floor with huge cracks. It will not work. Flex Seal is only designed to repair tiny cracks on a garage floor. As for the bigger ones, you’ll need to utilize special concrete repair products.
3. Flex Seal Doesn’t Thrive in High Traffic Garage Floors
A garage floor that is exposed to lots of traffic needs a better sealant such as epoxy. Otherwise, if you use Flex Seal, it will wear out prematurely.
Before brushing Flex Seal on your garage floor, evaluate how much traffic this part of your home experiences.
4. You’ll Need to Re-Apply Flex Seal Frequently
The ugly truth is that garage floors are treated harshly. It’s always being driven over. The garage floor also doubles as a workshop in most homes. Due to this extensive use, if you decide to use Flex Seal, you may find yourself re-applying it almost every year.
5. Long Term Costs
I understand that the main reason most people prefer to use Flex Seal on a garage floor is that it’s cheaper than other concrete repair or sealing solutions.
But if you project the long-term costs and performance, you’re better off exploring other lasting solutions.
The key takeaway from the above is that Flex Seal can be used on a garage floor. And there are a lot of benefits you can get which I’ll discuss below. But before you apply it, evaluate the factors above and confirm if it makes sense.

How to Apply Flex Seal on a Garage Floor?

You should start by getting some Flex Seal. Go for the liquid version because it’s much easier to apply on your garage floor with a brush. Get some painter’s tape and protective clothing as well.
Step 2: Clean the Garage Floor
The presence of dirt and contaminants on your garage floor can affect the adhesive strength of Flex Seal. So, make sure that you clean the floor with soap and water. Then let it dry. You can use a vacuum cleaner to suck out debris.
Step 3: Inspect and Make Necessary Repairs
Because Flex Seal won’t work on huge cracks, make sure that you repair them first. Otherwise, the Flex Seal will fail prematurely.
Step 4: Mask the Surrounding Areas
If you don’t want Flex Seal on your garage wall, make sure that you mask them using painter’s tape. This also helps prevent paint overspray.
Step 5: Start Brushing the Flex Seal on Your Garage Floor
Thoroughly shake the Flex Seal container to ensure all the ingredients are evenly mixed. Pop the lid and start brushing the paint on your floor. It’s best to divide the area into sections so that you can apply even amounts of the Flex Seal.
Step 6: Add an Extra Coat
Considering that this is a garage floor we are talking about, you need to add at least an extra coat for added protection. Flex Seal recommends that you wait for 24 hours before adding another coat. Make sure you adhere to these regulations.
Step 7: Let It Dry
Please note that Flex Seal dries to the touch within three hours. However, it’s not yet fully cured and shouldn’t be exposed to traffic. You need to wait for at least 24 or 36 hours before opening up the garage floor to traffic.
What Type of Garage Floors Can You Use Flex Seal On?
I have already mentioned that Flex Seal can be used on concrete garage floors. But garage floors come in different materials and it’s a good idea to know whether your floor is compatible with Flex Seal.
Here is a list of garage floor materials that are approved for Flex Seal application;

How Much Garage Floor Coverage Can I Get from Flex Seal?
If you’ll be using the brushable version of Flex Seal, a quart-sized container can cover around 75 square feet of space. so, you’ll need to calculate how many cans are needed.
As for the sprayable version, a fourteen-ounce can cover 6 square feet. The number of coats and how thick you are applying the Flex Seal contributes significantly to the coverage.
Should You Spray or Brush Flex Seal on a Garage Floor?
We all have our favorite approaches when it comes to spraying paint or sealants. But on a garage floor, it’s better to brush the sealant instead of spraying it.
Brushing Flex Seal guarantees precise application and minimal chance of overspray. If you spray it instead, there is a high chance of overspray and you won’t have sufficient control.
Whichever method you settle for, make sure that you are comfortable with it. Also, don’t forget to wear a mask and gloves.
How Long Can Flex Seal Last on a Garage Floor?
On a garage floor that experiences minimal traffic and exposure to the elements, Flex Seal can last for more than three years.
However, if your garage floor is always busy, you may get a year or a year and a half at most. In the latter scenario, you can always reapply Flex Seal every year. That should keep it in perfect condition.
