Factors To Consider Before Purchasing A Concrete Sealer

Now that you know the best and top-rated concrete sealers to protect various types of surfaces such as driveways, patio's and garage floors make sure check a sealer for the following features before investing your money in a product.  

The Different Types of Sealants

As there are many types of concrete sealers.  To help you choose the best concrete sealer for the job we've gone into more detail in the following categories:

Penetrating Concrete Sealer

Such sealers penetrate deep into the concrete to create chemical bonds. These are efficient sealers to offer maximum protection against external elements and moisture.

Uses: These products are incredible for guarding a surface throughout all seasons. Most of these sealers are breathable and allow moisture from water to escape.

Acrylics Based Sealers

This sealer produces a thin protective film on the surface. Such products are available in both water based and solvent formulations.

Applying Acrylic Concrete Sealer On Floor

Uses: Offers significant protection against chloride and water intrusion. Solvent-based acrylics deliver better results than water based concrete sealers for exterior surfaces. Softer acrylic sealers may require multiple coatings of a floor finish solution or wax on indoor surfaces.


These sealers create a protective film on the concrete surface, and you can opt for them in both water based and solvent formulations. 

Uses: They are thicker than acrylic sealers and feature incredible moisture resistance capabilities.


Create a high-build shielding film on the concrete surface. A large number of these sealers are two-component products that need mixing before application.

Uses - These sealers result in a long-lasting and hard finish. Such sealers also offer an abrasion-resistant finish and are incredibly water repellent.

Penetration Capabilities

Most users are surprised to note only short-term results no matter how expensive a sealer is. The truth is that a concrete sealer's performance depends mainly on its penetration abilities. The more profoundly it goes into a surface, the more protection it offers to guard it against water, daily wear and tear in hot/cold temperatures.

A professional-grade concrete sealer is capable of penetrating deep into the porous nature of a substance. Check sealer reviews and ratings to know if a sealer can seep into the kind of surface you want to seal inside or outside your living space.

Some concrete sealants require just a single application whereas others may need many coasts to penetrate into the concrete. Follow the instructions that come with each product. The best sealers do not just settle on the top of a surface but go deep into it to chemically bond with it.

Penetration depends on the viscosity or thickness of a sealer. Some users believe that an efficient sealer ensures complete locking of moisture to protect a surface. In reality, it can lead to many complications, depending on the environment you live.

Hence, most brands prefer manufacturing breathable sealers that do a great job at protecting the surface without creating any rot or slickness issues.

Durability of the Best Concrete Sealers

Spending money on a sealer and applying it brings no benefits if the results are temporary. It is best to use a sealer that is manufactured specially for a particular kind of surface. This way you get long-term results without having to reapply the concrete sealer frequently.

Concrete After Concrete Sealer Treatment

We know that brands mostly advertise their best concrete sealers as efficient ways to offer protection against scuff, UV radiation, dirt and are water repellent. What they fail to promote is the information regarding whether the sealer is designed to withstand car traffic of household chemicals.

Naturally, a sealer that is produced to protect your kitchen sinks and countertops should not be able to deliver the same results on your pavers and driveways.

Follow the application instructions that usually come with a sealer. How you apply a solution can also have a significant effect on the durability of a sealer’s results.

Thanks to the popularity of sealers, many options are exclusively manufactured for countertops, sinks, patios, pavers, and driveways. Choose the right kind of product to deliver the best of results.


Most of today's top-rated sealers claim to be non-slip. However, users may report varying results. Since sealers are for penetrating deep into concrete or natural stone surface, it should smooth out the natural texture of a surface.

Beware of fake products that only settle on the top to add a slippery effect to a surface. Some users include some additive either before the application or with the sealer. However, this can put an additional cost on your sealing project. Choose a concrete sealer that has its non-slip additive.

You can also purchase a non-slip concrete sealer. That is also another measure of the quality of a sealer. The more penetrating and useful it is the less smooth finish it gives to a surface.


There is no ‘best' finish when it comes to a concrete sealer. If you desire a sleek and shiny look, you can shop for a wet-look sealer that adds a glossy finish to any surface. People who prefer a subtle shine that enhances the beauty of their surfaces usually opts for a semi-gloss finish.

A satin finish guarantees a smoother appearance whereas a matte finish exudes elegance. Many of the best decorative concrete sealers deliver a matte finish for a natural look. Such a finish does not reflect light and allows rich textures and colors of the substrate to shine on their own.

Non-Toxic Composition

Make sure that your choice of concrete sealer does not feature any toxic or harmful compounds that can leave detrimental effects on the well-being of your children. However, a large number of advanced sealers are non-acidic materials. A concrete or crack sealer that does not emit any fumes or a strong smell is usually considered safer choice to use - but make sure to check the labeling.

Applying Non Toxic Concrete Sealer

Frequently Asked Questions

What does concrete sealer do?

Concrete sealer is applied to provide a layer of protection to your concrete surfaces. It protects the cement from surface damage, corrosion, abrasions, and staining. Hence, it does not only extend the time of the installation but also improves and maintains its appearance.

What is the best concrete sealer?

The best concrete sealer depends on the project your working on.

When you're sealing a concrete driveway, basement, garage floor, patio, pool deck or outdoor walkway a penetrating sealer (such as silane, siloxane, silicate or siliconate) is usually best. These types of sealers penetrate deep into the concrete and create a chemical bond giving maximum protection against external elements and moisture extending the life of your concrete surface.

The best concrete sealer for concrete countertops, food processing areas, interior stained concrete and high traffic indoor floors is usually a topical sealer (such as epoxy, acrylic, polyurethane or urethane). Topical (or film-forming) sealers are used to preserve and protect the appearance of your concrete and can add can a decorative high gloss or wet look finish.

How long does concrete sealer last?

This answer can vary depending upon circumstances. How long the sealer will last on your concrete surface will depend on the exposure conditions and how well you maintain the surface. Generally, urethane-based sealers and epoxy-based sealers gives good and long-lasting protection that will normally last for many years before reapplication.

When to apply concrete sealer?

You should allow new concrete to cure for at least 28 days or as recommended by your sealer’s manufacturer. Most sealers need to be applied when the concrete is dry because applying to a damp surface may cause haziness or loss of adhesion. The air temperature should be over 50 F (10 C) for at least 24 hours after it is applied. Drying times can be as long as three days. On the other hand, in the case of acrylic resin and some reactive penetrating sealers, both silicones, and silicates, must be applied after the new concrete can withstand the weight of the installer.

How many coats of concrete sealer?

A concrete sealer is best applied in two thin coats. The first application will serve as a primer, which will disappear into the concrete surface. This may not look good after the first coat. The second application will present a smoother look, which adds color enhancement and gloss. When coating for the second time, make sure to apply in reverse direction or perpendicular direction with the first coat to ensure an even exposure. Make sure the wait the specified time recommended by your manufacturer between coats, which usually two to four hours.

How long for concrete sealer to dry?

The dry time for a concrete sealer will depend on several factors, including the temperature, humidity, dew point, and the type of concrete sealer that will be applied.

Most concrete sealers feel dry to touch in around one to three hours but you should wait much longer before using your surfaces.  For penetrating sealers wait at least 24 hours before using your surfaces and for topical sealers it will usually take around 48 hours to be fully dry.

How to remove concrete sealer?

There are 2 ways to remove concrete sealers, with manual work or chemicals. The manual method involves sanding, blasting or grinding. The chemical method involves use of chemical strippers such as Methylene chloride, N-Methylpyrrolidone or Dibasic esters. Most people opt for the chemical method to reduce damage to the surface and save time and clean-up.


Stains, erosion, and cracks can deteriorate any surface. Sealers provide a protective layer on not just for concrete and cement but also several other kinds of surfaces. If you are looking to cut down home repair and renovation costs, investing in a professional grade and good quality sealer goes a long way for maintaining your interior and exterior surfaces without spending a fortune.

Your driveways, patios, pavers, sinks, countertops and tiled floors can last much longer when you apply a good quality sealer for protection. This way you can add more value and durability to your workplace or house.

Lastly, the best concrete sealer is the one that suits your specific needs and fits into your budget. There are a wide range of concrete sealers are available, and many are designed specifically for your requirements. Be sure to follow our buying guide to make the best decision.
