Best Concrete Sealer for Exterior
Our Top Pick
PS101 Concrete Sealer
Enjoy the power of deep penetrating siliconate sealer that protects your concrete for up to 7 years.
*Not intended for asphalt application
When you buy concrete sealers from a big brand store, you’re not getting the best of the best. You’ll be left with an inferior product that will end up costing you more in the long run. PS101 was created for industrial use and now you can enjoy the luxury of the best sealer right at home.
With PS101’s deep penetrating sealing action, your concrete will be safe from:
- Freeze-thaw damage
- Scaling and spamming
- Damage from acid rain
- Deicing chemicals and salts
- UV Damage
You’ll be able to enjoy limited dirt buildup and less mold and mildew. You won’t have to worry about cleaning your concrete every so often, it’ll practically clean itself. The biggest factor to consider is how you’re increasing the longevity of your concrete’s life when you seal it properly.
With the help of PS101, your concrete will last the test of time. Replacing concrete is costly, and when you live in a climate that’s prone to freeze/thaw cycles, your concrete is at risk of being damaged.
Depending on the abuse your patio or driveway will see, you can expect this concrete sealer to last 5-7 years. That’s three times more than the currently recommended concrete sealers at big brand stores.
If you’re worried about installation, you can DIY with a roller. It is recommended to rent a low-pressure sprayer which will allow you to go faster and spread the sealer evenly. If you do go with the roller option, be aware that you need to apply it fast to create the best possible seal.
PS101 is a water-based concrete sealer that won’t alter the look of your concrete. If you’re looking for a more “gloss wet” look, check out the TS202 acrylic topical sealer that will leave your concrete with a low-gloss finish.
You won’t have to worry about buying an inferior product with ConcreteSealersUSA. Make sure you apply the concrete sealer, and you’ll have concrete that’s sealed for years to come. 5 gallons is enough for 1250-2250sqft and should be enough to last quite a while with planned recoats.
Best Concrete Sealer for Inside
*This product should not be used on surfaces that have preexisting topical coating like epoxy, polyurea or polyspartic.
Whether you’re in the garage or have concrete surfaces in your home, accidents happen. One minute you’re changing your car’s oil and the next your poor garage floor has been stained for life. ConcreteSealersUSA’s TS210 is the answer to life’s common problem.
You’ll be protected from:
- Deicing Chemicals
When you’re in the garage all day, spills are a daily occurrence. You won’t have to worry about stains any longer when your concrete is protected with the TS210. The TS210 can also help your garage floor by reducing:
- Dirt buildup
- Mold and mildew
- Freeze/thaw damage
One downfall for cheaper products is that they’re prone to hot tire pickup, you’ll be able to drive your vehicle in and out of your garage without worry as this concrete sealer is hot tire pickup resistant. It’s also UV resistant and won’t break down or yellow if your garage gets sunlight.
The TS210 leaves a natural matte finish, so you won’t have to worry about altering the look of your concrete. You’ll be able to enjoy sealed concrete with the added protection traditional acrylic sealers can’t provide.
This concrete sealer can last up to 5 years. That’s 5 years of protection from spills, mildew, and freeze/thaw damage that your garage floor won’t have to go through. Repairing your concrete can be fairly pricy, but sealing your floor will ensure that you won’t have to worry about stains that can’t be removed.
1 gallon is enough for 300-500 square feet. You’ll be able to install it yourself if you’re quick with a roller and can ventilate your garage. It can also be used on stamped concrete, acid concrete, stained concrete, stenciled concrete, overlaid concrete, exposed aggregate brick, concrete pavers, and broom or smooth troweled concrete surfaces.
If you’re apprehensive, remember that professionally applied epoxy or polyurea coating can cost upwards of $2000. The cost of the TS210 is a drop in the bucket compared to the protection you’re paying for and the years it’ll add to your concrete life.

Can I seal my own concrete?
Yes, you can seal your own interior and exterior concrete floors. However, like any construction project, there are several important steps you need to follow to ensure you seal your concrete floors properly.
One of the most important things to remember when it comes to sealing your concrete surface or concrete driveway is to not get overwhelmed with information.
Concrete sealing is a big industry, and there are many technical applications where specific products and installation methods are required. However, for a DIY sealer, the most important thing is to find the right products, and ensure you follow the instructions.
Along with following the instructions, properly cleaning the floor, and allowing sufficient curing time will help ensure your floor lasts a long time. You will save tons of money when you take a few hours on a weekend to seal your concrete.
How long will it take to seal concrete?
There is no exact amount of time it will take to seal your concrete. However, unless you are a professional, it is not something that can be done in one afternoon.
From the time you start, to the time you can safely drive your car back into your garage could be anywhere from 2-5 days. This will depend on the type of sealer you are using, how many coats you need to apply, and a couple of other factors.
It is crucial that you are not rushed when sealing concrete. Not giving the extra 24 hours required to properly cure could significantly reduce the lifespan of the sealant.
How long do concrete sealers last?
Concrete sealers will last between 5 and 10 years, but if you are lucky, and you do a good job applying the sealer, you may be lucky and get 20 years out of it.
The amount of time your sealer will last will come down to what you are doing in the garage. For example, if you are bringing your car in and out of the garage on a daily basis, and you have a couple of oil leaks, the lifetime will be diminished.
If you are simply using the garage to store tools, the sealer will last significantly longer because there is less wear and tear on the floor.
Signs you need to reseal your concrete
An easy way to determine if you need to reseal your concrete is to see if the concrete is absorbing water or other liquids.
This can be done by pouring water over your concrete floor. If the water infiltrates into the concrete, then it is a sign you need to reseal your floor. If the concrete remains on the surface of the floor, your concrete is sealed.
If you have painted your floor previously, you should remove the paint from the concrete before sealing.
Choosing Between Acrylic and Penetrating Concrete Sealer
There are two main types of concrete sealers: Acrylic concrete sealers and Penetrating concrete sealers. Acrylic “topical” concrete sealer is applied on top of the concrete, and penetrating concrete sealer penetrates into the surface of the concrete.
Each type of sealer has its advantages and disadvantages. One of the major differences is that a topic sealer will slightly change the look of the concrete(giving it that wet look), and may make the surface a little more slippery. Penetrating concrete sealer will have a more natural look.
There are other technical differences including breathability, but unless you are working in a large industrial warehouse, you do not need to confuse yourself getting to know all the technical information.
If you’re in your garage a lot, I would recommend going with a penetrating concrete sealer. If you’re looking to transform the look of your concrete, go with an acrylic sealer.
How Much Concrete Sealer You’ll Need
The amount of sealer required will be based on the area you are covering. Before purchasing your sealer, take some measurements in order to determine how much surface area you need to cover.
Depending on how many coats you’ll need, you will need to factor that in as well.
You will also need to purchase other materials in order to complete the installation. A spray pump is recommended but a roller can do fine if you’re quick.
Along with the tools required to apply the sealer, you need to factor in the other tools required to properly clean the concrete floor prior to applying the sealer.
If you have any oil spills, the chemicals required to clean the oil will add to your cost.
Sealing Old Concrete VS Sealing New Concrete
Whether you are sealing old concrete or sealing new concrete, the steps are very similar. The major difference is that you need to perform a couple of extra tasks when working with old concrete.
Prior to sealing old concrete, it is important to remove the old sealer. This can either be done mechanically (with the use of a grinder) or chemically.
Mechanically removing the old sealer can be a very messy process, and can deteriorate the existing concrete. Therefore in an ideal world removing the old sealer chemically would be the best option.
If you know what kind of sealer you had used in the past, bring this information to your local hardware store, as this information will help you find the best product. However, if you don’t have this information, your local hardware store should have products that can remove a variety of sealers.
It is possible to install a new sealer over an existing sealer, but there are very specific conditions that must be met in order to ensure compatibility. Ensuring compatibility can be very difficult, therefore it is often best to simply remove the existing sealer.
You shouldn’t need to use a solvent-based chemical stripper as they are more for thick coatings like epoxy, you can opt to use a less invasive biochemical stripper to remove your concrete sealer.
Once you have removed your existing sealer, it is important to fill any cracks that may have developed. Similar to the other products used, any kind of concrete filler that you find at your local hardware store will suffice.
Once you have done this, then you go as if it was a new concrete surface. Start by ensuring the concrete surface is clean, and proceed as if you were sealing a new concrete floor.
Will Sealing My Concrete Change Its Color?
The color of your concrete can be changed slightly depending on the type of sealer you use.
If you use a penetrating sealer, the color will not change.
If you use an acrylic topical sealer (a sealer that is applied directly on top of the concrete), the color could change.
Many clear acrylic concrete sealers will not drastically change the color of the concrete but instead will give the floor a more “glossy” look.
If you wish to change the color of the concrete, you can apply a “tinted” concrete sealer, which will alter the color.
Regardless of the type and brand of concrete sealer you choose, the most important thing is to read the label. If the sealer will significantly alter the color of the concrete, it will be indicated on the label.
Application Tips (dos and don’ts)
For a full guide, you can learn how to seal your garage floor. You can keep the tips below in mind as well.
1. Consider professional installation
You will never get two people to agree 100% on the best way to install concrete sealer. A professional is going to be able to guide you through the process and you won’t need to worry about buying extra tools you won’t use again.
2. Don’t rush
Give yourself plenty of time to ensure the concrete is dry before you install the sealer. Ensure you follow the instructions and give ample time for the product to cure.
3. Don’t walk over your work
Make sure you plan out which parts of the floor you’re going to seal first. This normally involves separating the floor into four sections. Make sure you don’t walk over the sections that have been sealed.
If you’re planning on sealing your concrete driveway, then it’s best to park your vehicle in your garage or on the street to let the sealer adhere to the concrete.
4. Do ensure you clean the floor properly
Make sure you remove debris, and remove any grease prior to sealing your concrete floor.
5. Do read and follow the instructions
Make sure you read the instructions prior to sealing your concrete, and make sure you follow all the instructions. This includes waiting times, application methods, and so forth.
6. Do Provide adequate ventilation
Read the instructions and warning labels on your concrete sealer. Ensure you have sufficient ventilation to prevent you or anyone you work with from getting sick. In a garage, this normally involves keeping the garage doors open. If proper ventilation cannot be achieved, install a fan and ensure you take frequent breaks.
7. Do Wear Proper PPE (Personal Protective Equipment)
Ensure you are wearing appropriate clothing. This could include gloves, glasses, pants and more. Some concrete sealers can be dangerous if you get it on your skin or in your eyes.
Personally, I recommend sealing your garage over the best garage floor paint. It’ll last a longer time and you can still add aesthetic to your garage.
Take your time with the process and you’ll be able to enjoy a sealed concrete floor with the best concrete sealers you can find. You’ll be able to enjoy a wet look with an acrylic concrete sealer. Even if you have decorative concrete, you’ll be able to enjoy sealing your concrete as well.
