What Are Concrete Sealers?
Think of it as paint for your concrete. Concrete sealants protect your concrete from UV rays, cracking, efflorescence, fading, and discoloration making your property more attractive and worth more.
What Are The Different Types of Concrete Sealers?
Before you choose the correct product for the job, let's explore the different types of concrete sealer to help you decide which to use:
-> Penetrating sealers
Penetrating sealers contain silicates that reach down into the pores of the concrete rather than forming a protective layer on the top. Penetrating sealers are great at making water bead on the top of the concrete, and they're known for almost completely reducing water absorption.
Penetrating sealers are typically water-based products, so that means they have low VOC content and are safer to use than epoxies and solvent-based sealing products.
How long do penetrating sealers last on concrete? Penetrating sealers are said to be the longest-lasting formulas with the potential to last up to 25 years.
Choose a penetrating sealer if you're looking for durability.
Epoxies are a two-part paint formula that dries hard as a rock once they are mixed and applied to the concrete surface.
How long do epoxies last on concrete? Epoxies last 10-20 years with impeccable quality. Epoxies aren't typically used on outdoor surfaces because of their expensive cost, but outdoor concrete painting with epoxy will surely last a long time.
Polyurethane sealers are either water or oil-based, and they form an ultra-thick barrier on the surface of the concrete for superior protection.
How long do polyurethanes last on concrete? Sources say that polyurethanes last anywhere from 5-10 years, but the estimated duration is more accurately displayed on each specific polyurethane product.
->Acrylic concrete sealer
Homeowners--Acrylic sealers form a water-based sealer on the concrete's surface. You might try a silane-siloxane or another type of acrylic sealer for a nice consistency in your concrete (try wet look sealers for outdoor patios and other exterior concrete)
How long do acrylic products last on concrete? Acrylic concrete sealer lasts for 1-3 years on exterior surfaces, but we still recommend using it over other products because of its low VOC content, meaning it's safer for the environment when compared to polyurethanes and epoxies.
Acrylic sealers are known to be more breathable for their ability to let the water breathe off of the concrete surface.
How Does Concrete Sealer Work?
Concrete sealer is applied to the surface of the concrete using a paint sprayer, roller, paintbrush, or push broom.
Depending on the type of concrete sealer you use, the sealer either penetrates the surface of the concrete or provides a protective layer on the top that helps to prevent cracking, fading, and discoloration. Most concrete sealers are UV resistant meaning they won't yellow with the years, and they protect your concrete surface from being damaged by the sun over time.

What To Look For In The Best Sealer For Concrete?
For interior applications, we say that epoxy paints are the best sealer. Two coats of epoxy last for years and years, and it also makes for easy cleanup. For example, motor oil cleans off of epoxied concrete like it was never there--that might not be the case when spilling oil on other products.
The best concrete sealers are resistant to water, chloride, deicing salts, and oil, and the best way to understand what each penetrating sealer does is by reading the label before buying on Amazon.
Here's what to look for on the container and what it means:
Siliconates prevent water from damaging the concrete. Penetrating sealers among other products contain siliconates.
- Oleophobic additives
These repel oil making it easier to clean from the surface. Concrete sealers containing additives are a great choice for surfaces that will be exposed to frequent oil spills or drips (epoxy paint is super easy to clean oils off of, but be careful with brake fluid--that will destroy it).
- VOC (Volatile Organic Compounds)
Volatile compounds emit harmful gas into the atmosphere once the paint is applied to the surface.
You'll notice that each concrete sealer product states how long it lasts for indoor and outdoor applications (read the label on the container).

How To Apply Concrete Sealer The Right Way?
Below is a video representation of how to seal concrete and a verbal explanation of how to correctly perform the work.
So you've bought the best product for the job, and now it's time to apply the concrete sealer to your DIY project. Don't worry, we have all the right tips to help you successfully perform the work.
Here is a 5-step system to help you properly seal your concrete:
Step 1: Clean/degrease the concrete surface
The first step in sealing your concrete surface is applying a degreaser to remove the grit and grime. Any degreaser will work. Spray the entire concrete surface down with a degreaser, and use a scrub brush to scrub the entire area (depending on how dirty it is).
Then, use a pressure washer to thoroughly clean off the surface of the concrete.
Step 2: Polish and etch the concrete
After the initial cleaning process, mix some concrete etch with water and scrub it into the concrete to open up the pores of the concrete. Use your pressure water or a hose to clean the concrete once again before applying the sealant.
Step 3: Apply the concrete sealer
Now it's time to apply the concrete sealer using the best method available to you. It's also important in this step to read the label of the specific sealer you'll be using and follow the instructions accordingly. Here are a few different methods you might use to apply concrete sealer:
- Applying with a sprayer
We recommend applying penetrating sealers, acrylic paints, and even polyurethanes with a paint sprayer (we recommend using a paint roller for epoxy).
The most important part when painting with a sprayer is making sure you properly set it up. You'll want to spray a small amount of sealer onto a test surface before starting the job to ensure that the spray is misting evenly.
Another important step when spraying with a paint sprayer is properly cleaning it afterward. Again, follow the manufacturer's instructions for proper paint sprayer maintenance to help your paint sprayer last for the jobs to come.
- Applying with a paint roller
Using a paint roller is an easy and inexpensive solution for applying a concrete sealer. We recommend using an extender pole when applying paint with a paint roller to avoid getting on your hands and knees.
- Applying with a paintbrush
Using a paintbrush is a perfectly acceptable option for applying a concrete sealer, but it will certainly take longer than using a paint roller or sprayer.
- Applying with a push broom
Applying sealer with a push broom is easy--simply pour the sealer onto the concrete surface, and push it evenly across using the broom.
Step 4: Apply a second coat of sealant if necessary
There are times when one coat doesn't quite do the job (especially on porous concrete), and that's where you'll need to go ahead and apply another coat.
Since you've already applied a generous amount of sealant, the second coat should only require a fraction of the amount of sealer used on the previous coat.
Step 5: Wax/polish the sealant if desired
Waxing your concrete with a floor polisher is always an option for making your floors as clean as possible. You can either use an electric floor polisher or a microfiber floor mop to apply the wax.
When applying the wax, pour it onto the floor in small amounts (about the size of a pancake), and work in each area of the floor to make the concrete shine.
Other supplies needed for sealing concrete?
As you might have guessed, you're going to need more than just a concrete sealer to get the job done. Here's a comprehensive list of tools that a professional painter keeps in his/her inventory to knock out any concrete sealing job:
We highly recommend that every painter uses a paint masker for covering up undesired surfaces when painting. You can pick up a 3M paint masker off of Amazon for the best price.
Painter's tape/Masking film
Aside from a paint masker, you'll need some painter's tape and masking paper/film to attach to it. Buy painter's tape and other masking materials online or at your local paint store.
Concrete polisher/Diamond polisher/Floor polisher
You may want to polish the concrete before sealing for a smoother look. Although purchasing a diamond rotary polisher is expensive, most home improvement stores rent them out for daily use at a reasonable price.
Paint roller/Paint sprayer/Paintbrush
You'll need the appropriate method for applying your polish of choice. Picking up a paint sprayer is never a bad idea to serve you on the projects to come, but concrete sealers can also be easily applied with a paint roller or even a paintbrush.
Drop cloths help to eliminate messes when painting/staining/sealing concrete which is why we recommend you have a drop cloth in your arsenal of paint materials.
Don't forget the proper solvent for your particular project. For most of these products, paint thinner or mineral spirits will work just fine, but if you're using epoxy you'll need acetone or lacquer thinner for effective cleanup.
Your sealant of choice
Don't forget your sealant of choice! We've made some quality recommendations, so scroll up and click the link to purchase high-quality concrete sealers.
We recommend using a degreaser and scrub brush to thoroughly clean the concrete surface, even before etching.
Use a scrub brush to scrub the degreaser when cleaning, and you'll also need it to work the etch into the concrete when prepping.
Some concrete sealers can be applied with a push broom. Read the label of your specific sealer of choice for proper application instructions.
Using a power washer to clean the surface of the concrete is the most effective way of cleaning up before applying the sealer. Remember, the cleaner your concrete is, the better the sealer will adhere to its surface.
Purchase a bag of concrete etch off of Amazon, and apply it to the concrete before sealing to help open up the pores of the concrete--this creates the potential for maximum adhesion.
