How do you apply epoxy sealer to concrete?

This post is an overview of the different types of sealers and how you can apply them to your concrete floor or countertop. First, I’ll explain why you should use a sealer, then I’ll introduce the different types of sealers and include some examples. Finally, I’ll walk you through how to apply epoxy sealer to concrete.

Why Use Sealer?

Sealers are used for two main reasons:

  • Protect the concrete from damage or deterioration due to water penetration, chemical spills and salts that can lead to cracking and spalling (chipping). When this happens, it exposes the surface underneath to further deterioration as well as making it unsafe for people using your floor because they could slip in ice patches during cold weather or trip on cracks in warm weather.
  • Change the appearance of the surface by giving it a sheen that makes it look more luxurious than dull gray poured concrete.

How do you apply epoxy sealer?

Get ready to start the application process by removing all items from the room in which you will be applying the epoxy. Spread out a drop cloth and move all furniture, plants, rugs and other objects out of the room. Wear protective gear such as gloves, eye protection, disposable coveralls and shoes that cover your entire foot. Open any windows to ensure proper ventilation if necessary.

Prepare your floor for sealing with epoxy by cleaning it thoroughly with a wire brush or industrial cleaning solution. Scrape away any dirt or debris on the concrete surface so you can apply an even coat of epoxy sealer to it later on.

Apply a primer coat of epoxy sealer by pouring it slowly into one corner of the room and spreading it evenly across the floor with a roller brush according to package directions. Allow this layer to dry completely before proceeding further; drying time is usually between 12 and 24 hours but may vary depending on conditions such as temperature and humidity levels in your home.

What is the difference between concrete sealer and epoxy?

There’s a big difference between epoxy sealers and concrete sealers. One is better than the other. Find out more about the advantages of using each kind of concrete sealer, as well as why you should use epoxy sealer on your concrete.

Can you seal concrete with epoxy?

Epoxy is a great sealer for concrete surfaces. You can use it on both new or old concrete. Epoxy works well in garages, basements, and patios where you have to worry about things like oil and chemical stains. The epoxy will turn into a solid, durable surface that is easy to clean up and maintain.

Do I need to prime concrete before epoxy?

You want to make sure the concrete is porous before you apply the epoxy. If it is not, then no primer is needed. To check, pour a small amount of water in several different areas of your concrete surface and let it sit for 10-15 minutes. Wipe up the water after this time and see if any moisture has been absorbed into the concrete beneath. If so, then you need to prime your floor before applying epoxy sealer. Don’t worry! The process is easy and doesn’t take much time at all.

Before you begin priming, make sure that there aren’t any holes or cracks in your floor that could allow moisture to leak out from underneath the epoxy sealer coating later on in life (the payoff for not properly cleaning these spots before applying epoxy sealer).

The first thing you will want to do for cleaning floors before applying an epoxy sealer is sweep up any loose debris like hair or dust that may have accumulated over time. Next, using a mild detergent soap like dish soap and some warm water mop down all surfaces that are receiving an application of KILZ® Original Sealer & Stain Blocker Primer/Sealer on them with this solution (making sure not to leave behind any excess liquid). It will help loosen up anything that cannot be swept away manually.

Can you epoxy seal outdoor concrete?

Yes you can! Epoxy is a great choice for outdoor concrete. It’s durable, resists UV rays and moisture, and will not discolor over time. Epoxies are also highly chemical resistant so they’re perfect for use around swimming pools, on patios or in garages or warehouses.

If you plan to apply epoxy to outdoor concrete follow these steps:

Can you put a sealer on concrete?

You can apply a sealer to concrete. To do so, you’ll need a high-quality concrete sealer, a roller or sprayer, and cleaning supplies. The sealer should be applied evenly to the concrete surface with a roller or sprayer, and you can also use a brush to get into hard-to-reach areas. As with any project involving chemicals, it’s important to read the label on the sealer before using it.

How long does epoxy sealer last?

Epoxy sealer can last decades! If you want your floor to stay fresh, though, it’s important to keep up with maintenance. As you know, chemicals and other contaminants can get between the epoxy sealer and the concrete floor. This essentially creates a barrier which prevents the epoxy from adhering properly to the concrete. If this happens, water will seep in and cause stains and damage over time.

To prevent this from happening, you need to make sure that your epoxy coating stays clean. Do this by sweeping regularly (a good idea for any home) and mopping when necessary. You may also want to consider waxing your floor about once a year. This will add another layer of protection between the epoxy sealer and any dirt or debris that might be on your floor.

Is it better to seal or paint concrete?

Sealing is preferable to painting for many reasons. If a garage floor is well-sealed, it can last 20 years or more without any further treatment. It’s also much cheaper to seal than paint, and you can do it yourself if you feel up to the task. Concrete sealants are quicker and easier to apply than paints or coatings, and they provide a clear finish that won’t chip or peel. Lastly, sealing concrete protects the surface from oil spills, chemicals and other contaminants that can be extremely difficult—if not impossible—to remove after they stain painted floors.


Now that we’ve covered the steps, let’s quickly recap. First, remove all dust in the area to be sealed by sweeping or vacuuming it and then use a damp towel (or similar) to wipe away residual dust particles. Next, apply epoxy sealer using a brush, roller or sprayer. Be sure to evenly coat all of the surface and keep an eye out for any pooling or puddling in low spots of your floor. Finally, allow some extra time after your initial application for the epoxy to fully dry before applying any additional layers needed for optimal coverage.

Sealing concrete is an important step toward preventing deterioration of your floors caused by moisture damage and corrosion. It will also help prevent staining on your floor due to oil leaks, antifreeze spills, and other common automotive fluids that could come in contact with your garage flooring. When using epoxy products there are other precautions you should take as well—like wearing proper safety equipment when mixing and applying the sealant—but if you follow these steps you should be able to achieve optimal results with minimal trouble!
