Sealer for Concrete Countertops Buying Guide

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

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

Expected Wear

While 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 repeatedly, 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 you might have to get another to seal your patios or countertops.

Consider taking a measuring tape (or another thing for measuring) 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, selecting a sealer with food area safety is key.

Exterior Use

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

In that case, you will see a couple of models with an individual logo indicating whether the sealer is safe for outdoor appliances. If 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.


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 buying a concrete sealer, check out the “LOW ODOR” logo to get rid of that issue.
