What Concrete Countertop Sealer Is

A concrete countertop sealer is a protective coating that is applied to your concrete countertops to make them more durable and easier to clean. Sealers come in liquid, gel, or powder varieties and are usually made from silicate materials like sand, copper, or aluminum. A sealer will also help maintain your concrete’s natural color while protecting it from stains caused by the everyday use of hot or acidic foods. A good concrete countertop sealer will prevent stains from occurring, while also protecting your surfaces from everyday wear and tear. Concrete sealers are made of many different chemicals, so it is very important that you do your research beforehand to make sure the sealer is right for your needs.

kitchen-countersConcrete Sealer and Wet Look

Wet look of concrete sealer? Concrete after applying a special sealer can really have a wet appearance. Can you imagine this kind of concrete countertop? It’s amazing!

The water look effect is achieved by using a special sealer that creates small glass beads when applied onto cement surfaces. These tiny bubbles cling onto cement surfaces like air pockets & catch sunlight reflection creating the wet look texture. Depending on how deep these bubbles are, the color of concrete may slightly appear different.

Outdoor Concrete Sealers


Exterior concrete sealer must be able to stand against harsh and challenging environments like the beach, and areas that are regularly exposed to salt water spray.

A good concrete sealer for outdoors is a product that imparts very long-lasting protection against water, sun, dirt, and other elements without leaving any residue behind (but not necessarily an invisible one). It should also not be prone to peeling off as this will only expose your original concrete surface to more damage in the future.

Frequently Asked Questions

Are concrete sealers food safe?

Concrete sealers are food-safe when cured. All manufacturers currently selling concrete sealers, recommend that you wait at least 7 days for the product to fully cure before applying food and preparing or eating foods in the area where it was applied.

How often do concrete countertops need to be sealed?

Depending on location, you should check your countertop every year and apply a sealer if it is damaged or begins to show wear. In glossy or polished concrete counters, checking for scratches and wear is a good idea more frequently as polish can be worn away quickly with frequent use of metal utensils or heavy pots and pans. Cracks that are beginning to form may also need attention before they spread into larger cracks.

How many coats of sealer do I need for concrete countertops?

There are two factors that determine how many coats of sealer you will need and also the method used to apply it. The first is how much porousness exists in your concrete itself. The second is how natural you want things to look. If your concrete has lots of pores and high porosity, then more coats will be needed as each coat seals a fraction of what normal concrete does.

Thus if you have a 5% porosity or so, you could conceivably have to use three or four thin coats whereas if it’s 20%, only one coat might be needed. This same rule applies if you want really glossy enamel-like finishes as opposed to semi-gloss or satin matte finishes where fewer layers may indeed be required again.

Can you use polyurethane to seal concrete countertops?

No. Polyurethane is a surface coating used on wood to fill imperfections and give the appearance of fine furniture. It is not designed for use on concrete, masonry or stone surfaces. Instead, consider using an epoxy-based sealant designed for exterior cement substrates. Because polyurethane is not chemically compatible with concrete, it will delaminate and come off the concrete surface within a year or two.

How long does the concrete sealer last?

Concrete sealer lasts for years, but there is no concrete sealer that will last indefinitely. As it’s made of water-soluble material and not bound together as concrete, it can dissolve if exposed to a lot of moisture. However, a normal amount of moisture won’t damage the sealer that you laid down on your countertop or any other surface. You do need to treat the sealed area regularly so moisture doesn’t get in between its cracks and lead to the growth of mold spores and mildew which could mar the look of your countertop over time.

Does sealer darken concrete?

Concrete sealer may darken concrete slightly depending on the type of product used.

How do you clean concrete countertops before sealing?

You just clean them of loose stuff and then seal them, the way you would any other surface. They should be dry before sealing.

Is there any difference between concrete and cement countertops?

The short answer is no. Concrete and cement are the same things. Cement is a powder that is made of limestone, clay, and sand. When it is mixed with water, it forms a paste that can be molded into any shape. Concrete is made by adding aggregate (small stones or gravel) to the cement paste. The concrete is then poured into a form and allowed to harden.

Can you apply a concrete sealer over the old sealer?

This is a question that can be difficult to answer, as there are many different types of concrete sealers on the market. In general, it is usually recommended not to apply a new sealer over an old one, as this can result in a build-up of sealers that may not be effective.

How can you tell if the concrete is sealed?

You can tell if the concrete is sealed by checking for a wet or oily look on the surface. If the concrete has a wet or oily look, it has not been sealed and needs to be sealed. Also, you can check the surface with a piece of dry paper towel. If the paper towel sticks to or is hard to remove from the concrete, it has not been sealed and needs to be sealed. Also, try to drop a few water droplets on the surface. If the water droplets bead up and stay on top of the concrete, it has not been sealed and needs to be sealed.


If you need to choose the best concrete countertop sealer, any of the above will do. These are some of the best sealers in the market. They comprise the top components used for sealer, which make them effective and deliver results swiftly. They are also safe for use and do not compromise the texture of your concrete.
