Concrete Sealants: What Are They, The Best Concrete Sealers and How to Apply Them

Spraying Concrete Sealer

Concrete sealers are a great way to protect concrete from the elements and extend its life. There are many different types of sealers on the market, but not all are created equally! In this post, we’ll go over what makes a good concrete sealer and which products you should look for when purchasing one.

What is Concrete Sealant?

The most common type of sealer used for concrete is an alkaline solution that contains phosphoric acid. When applied it reacts with concrete and forms a mineral layer that protects the underlying material from damage caused by weathering, staining and abrasion. These types of sealers are known as alkaline phosphoric acid solutions or APAs for short.

What Makes a Good Concrete Sealer?

There are a few key factors that determine whether or not a concrete sealer is worth using: durability, ease of application and price. 


The most important thing to look for in a sealer is how long it lasts! The longer the lifespan of a product, the better it will be at protecting your concrete from all sorts of elements. Ideally, you want one that can last up to 5 years or more. 

Easy Application

It’s also important to find a sealer that’s easy to apply and requires no special tools or skills. You’ll want one that comes with a sprayer if possible since this will make applying it much easier! 


Finally, you should look for a concrete sealer that’s priced competitively. You don’t want something that’s overpriced just because it has “concrete sealer” printed on the label! Most people are looking for value when they buy a product like this and not just a cheap piece of plastic in their hands.

How To Use A Concrete Sealer?

Once you have your sprayer built or purchased, it’s time to get started with the application! Here are the steps that you should follow when using a concrete sealer:

Step 1: Prepare Your Surface

The first thing you want to do is clean and prepare your concrete surface for application. You can either use a pressure washer or some warm water with soap if you’re cleaning off dirt and debris. If you have any cracks or seams in the surface, make sure they’re dry before moving on to step 2!

Step 2: Apply The Sealer

Now it’s time to apply the sealer! You’ll want to hold the sprayer about 30cm away from the surface and slowly move back and forth in a side-to-side motion. This will help you avoid getting sprayed on your hands and makes it easier to cover large areas of concrete.

Step 3: Allow Your Sealer To Dry

After about 15 minutes, remove the nozzle from the bottle and let it sit for an hour or so. You don’t want to leave this step out since it can cause peeling if allowed to dry!

Step 4: Clean Up And Reapply If Needed

Once your sealer has fully dried, clean up any messes and then apply another coat if necessary. This step is completely optional since it will increase the lifespan of your sealer, but not everyone wants to spend time applying multiple coats! 

Step 5: Wait And Enjoy Your New Concrete Sealer

Finally, once you’ve applied all of your coats, let them sit for at least 24 hours before using them or walking on them. It’s important that you don’t rush this process because you could end up damaging your new sealers!
