Sealer for Concrete Countertops Buying Guide

Picking up the best concrete sealer is not an easy task, as there we have tons of models with different features and benefits.

If you want to know which one is the right sealer and which one is going to suit your surface, check out this guide that is packed with a few core factors. And these factors will definitely help you in making a good purchase.

Expected Wear

While you go for buying a sealer, you might see a few models with expected wear times. You need to know how long it can protect your countertop from food stains, scratches, or wear and tear.

If you feel comfortable reapplying the coat again and again, then this feature is not that necessary for you. On the other side, if it seems pretty annoying to you, then picking out a sealer with expected wear times should be very important.

Check the Size of Your Surface

Checking out the size of your surface is a must before buying a concrete sealer. The sealer that you want to purchase should be perfect for your countertop. Or else, you might have to get another one to seal your patios or countertops.

Consider taking a measuring tape (or another thing for measuring) in order to measure your entire surface. After getting the size of that area, make sure to pick up a sealer that goes with it.

Food Area Safety

Do not forget to choose a sealer with food area safety, for which you can keep your foods in sealed areas. Around the marketplace, you will find numerous models with a specific ‘food-safe logo. If you have children or pets and want to avoid undesired accidents, then selecting a sealer with food area safety is a key; yes.

Exterior Use

If you need a sealer just for your countertops, then you can ignore this feature. On the contrary, if you are looking for a sealer for your patios, walkways, or garage floors, then definitely, you have to go with the one that is compatible with outdoor uses.

In that case, you will see a couple of models with an individual logo that indicates whether the sealer is safe for outdoor appliances or not. In case you apply indoor penetrating sealers on your walkways or patios, the surface might lose its appearance within a few days because of the rain and sunlight; so, bear that in mind.

Odor

Always pick up the odorless sealer, especially if you have breathing issues. But unfortunately, most of the penetrating sealers are packed with a strong smell. So, before going to buy a concrete sealer, check out the “LOW ODOR” logo so that you can get rid of that issue.

Frequently Asked Questions (FAQs)

Answer: According to our in-depth research and customer ratings, GlobMarble XS-327C stands out from the rest. This masterpiece is made of high-quality ingredients, and is ideal for both interior and exterior uses. It is food-safe, easy to apply, and dries out soon too.

#2. What should I use to seal my concrete countertop?

Answer: Keep in mind, countertop sealers and floor sealers are not the same. Even though both look almost similar, but their functionality is totally different. So, make sure to pick out the right sealer for concrete countertops.

You can get yourself the Rocklinite Labs CECOMINOD069855 if you need to use a sealer specifically for your concrete countertops.

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

Answer: It is okay to apply a single coat on countertops. But if you want to get the best result, make sure to apply two coats of concrete sealers. Keep in mind, you have to wait for a while between putting each coat to let the surface completely dry. By utilizing this technique, you might get your desired result, hopefully!

#4. How soon can you seal concrete countertops?

Answer: Whether you are using water-based sealers or anything else, you will not have to expend hours and hours to accomplish this task. In general, you can seal countertops within 2-3 hours or so.

#5. How often should you reseal concrete countertops?

Answer: It depends on your use. Usually, it is best to reseal countertops every 2-3 years for assuring perfect maintenance. In case you wait for more than 3 years, the coat will start to lose its real appearance!

#6. How do you prepare concrete countertops for sealing?

Answer: Before sealing, the first duty is to prepare your countertop. In that case, you should follow these ways and techniques below:

  • At first, you have to eliminate grease, oil, dust, or stains from the concrete
  • Tear off existing penetrating sealers from the surface
  • Ensure to open the concrete by applying the etching solution

The part of countertop preparation is almost done. For sealing purposes, you can:

  • Take the assistance of a sprayer or roller for applying a coat of sealer, and it should be thin as well.
  • Wait for a while for drying it out.
  • Go for a second coating after drying.

Even though the sealing task is done, you should wait for a few hours to get it completely dry.

#7. Can you use polyurethane on concrete countertops?

Answer: Of course, even polyurethane is one of the best things that you can use on your countertops or walkways. It basically packs a thick layer of sealer that provides better protection against all kinds of stains and scratches. Alongside, polyurethane offers less odor, which could be an advantage for most users.

Final Thoughts

We are completely done with our best sealer for concrete countertops. Hopefully, you have no more confusion after reading our reviews and comprehensive buying guide.

Well, always make sure to apply the right things in the right places. If you need a sealer just for your countertops, then you should consider picking up a sealer, which is compatible with indoor uses.

On the other side, if you need a sealer for versatile use, then purchasing a sealer for both interior and exterior uses will be a wise decision.

So, without further ado, move on to the marketplace to get the one that suits you best.
