Buying Guides on the Best Sealer for Concrete Shop Floor
A quick search on the internet will reveal many different types of concrete sealers available on the market. With so many options, how do you know which one is right for your shop floor?
The easiest way to find out is to read some buying guides that will help you compare and contrast the different products. Here are a few things to look for in a good buying guide:
Item Amount and Coverage:
The amount of concrete sealer you’ll need to cover your shop floor depends on the size of the floor and the product you choose. For example, if you have a large shop floor that sees a lot of traffic, you’ll need a sealer that covers a wide area and can stand up to heavy use.
On the other hand, if you have a small space that doesn’t see much foot traffic, you can get away with using a smaller amount of auto shop concrete sealer. Most products will cover approximately 90 to 300 square feet per gallon.
Select a sealer with the correct coverage for your project to avoid running out halfway through. Applying too much sealer can result in a slippery surface, while not enough may not provide adequate protection.
Dry & Cure Time:
The dry time is when the sealer dries to the touch, and the cure time is when it hardens. If you have a busy shop, you will want to choose a sealer with a shorter cure time to complete the job as soon as possible.
When you are not in a hurry, use a sealer with a longer cure time. If you’re short on time, you might want to consider a sealer that dries faster. Generally, penetrating concrete sealers will have a dry time of 1 to 12 hours and a cure time of 24 to 72 hours.
You can find many sealers that are eco-friendly and made from sustainable materials. Water-based concrete sealers have low volatile organic compounds, so they are safe for you and the environment.
Solvent-based sealers contain high levels of VOCs, which can be harmful to your health if inhaled. A water-based concrete sealer also has a low odor, so it won’t cause any irritation while you work and emit little to no fumes.
It depends on the type of concrete sealer, the environment, how frequently it is used and how long it will last. You will need to reseal your shop floor more often if you do a lot of welding or grinding.
When cars drive over concrete, the tire treads can cause small particles of the sealer to come off. For this reason, you should use concrete that is designed for high-traffic areas if you are sealing a driveway or parking lot.
Penetrating sealers are typically more durable than sealers because they soak into the concrete and become a part of the floor. This makes them less likely to peel, chip, or flake off over time.
A sealed concrete floor that lasts for 20 years is obviously going to be more cost-effective than one that only lasts for 2 years.
Easy to apply and Clean:
You want to ensure that the porous concrete sealer you choose is easy to apply and clean up. Choosing an auto shop concrete sealer with multiple application methods will make the job go faster. Most concrete coatings can apply with a pump sprayer, roller, or brush.
When it comes to cleanup, water-based sealers are much easier to clean up than solvent-based sealers. All you need is soap and water to clean up a water-based sealer, while a solvent-based sealer will require paint thinner or mineral spirits.
Is Concrete Sealer Necessary for a Shop Floor?
Concrete shop floors can suffer damage from a variety of sources. Heavy equipment, traffic, and even weather can all take their toll on the surface of the concrete. Over time, this damage can become extensive, jeopardizing the floor’s structural integrity.
Repair may be possible in some cases, but replacement may be the only option in others. As a result, you need to apply sealer on concrete floors to protect them from further wear and tear.
A penetrating concrete floor sealer can provide a layer of protection against oil spills and other common seepages. It can also make the floor easier to clean since dirt and debris will not be able to penetrate the sealed surface.
But some argue that concrete sealer is unnecessary and even detrimental since it can make the floor slippery. Although it makes the floor a bit slippery, it doesn’t lead to any accidents.
How Do You Seal Moisture Getting into Garage Floors from Outside?
In the warm summer months, it’s not unusual for concrete floors to start sweating. When moisture gets trapped under concrete surfaces, it can cause the floor to sweat, making it slippery and unsafe.
Mold and mildew can also grow due to moisture, causing health problems. Check the floor for cracks or holes and seal it well.
Then, you can seal the concrete with garage floor coatings. This will create a barrier between the concrete and the air, which can help to prevent moisture from seeping through.
You can install a vapor barrier to help keep moisture from getting trapped beneath concrete surfaces. Another way is to keep the temperature in your shop consistent to prevent condensation from forming on the floor. But these two options will require some level of maintenance and cost.
Is It Better to Paint or Epoxy Shop Floor?
When protecting and improving the look of your shop or garage floor, you have two main choices: paint or epoxy. You’ll have to figure out which option is best for you based on your garage floor’s condition and your personal preferences.
Paint is generally the more affordable option. It can provide a fresh new look for your garage or shop. Paint is not as durable as epoxy, and it is more likely to chip or peel over time.
Epoxy sealer, on the other hand, is more expensive, but it is also much more durable. It can resist stains and wear and tear much better than paint, making it an ideal choice for high-traffic areas like garages.
How Do You Protect a Shop Floor?

Now broom the surface in a circular motion to help the sealer penetrate into the pores of the concrete. Let the concrete coating dry for at least 24 hours, or follow the manufacturer’s instructions.
Step 04. Apply the Second Coat:
Apply a second coat in the same manner. This will ensure your concrete floor is well-protected against grease stains and dirt. Let the second coat dry completely or cure it before using the area.
How Much Does it Cost to Seal the Concrete Shop Floor?
When it comes to concrete, there are a lot of factors to consider. The amount of traffic, the climate, and the overall condition of the surface all play a role in how often it needs to be sealed.
Costs of labor also play a role in the final price. Prices will vary depending on the size of the area and the type of sealant used, but in general, expect to pay around $2 per square foot.
A small shop floor could cost less than $100. For a big shop floor, the price per sq. ft can be reduced to $1.2-$1.7 per square foot when more than 500 sq ft is being sealed.
