How to Test Concrete Countertop Sealers

While concrete countertops are known for their durability, sealers have a tremendous effect on the performance and aesthetics of the countertop. Concrete sealers are primarily responsible for protecting countertops from etching and stains, but sealers can also affect the sheen, texture, feel, and color vibrancy of the concrete. As you can see, quite a lot depends on the quality of the sealer you choose to use. Unfortunately, most people give very little time to choosing the right concrete countertop sealer for the project.

Testing is an excellent way to ensure that you have selected the right sealer. While the process of choosing a sealer might seem simple enough, that’s usually not the case. Testing is not only an easy but also an incredibly accurate method for ensuring that the sealer you have selected will perform as expected. Because concrete countertop sealers tend to react in different manners to different types of substances based on the length of exposure time, it’s important to test a variety of substances.

Performing a Sealer Test

 Among the substances to test for include yellow mustard, red wine, coffee, water, rubbing alcohol, acetone, vegetable oil, vinegar, lemon juice, liquid dish soap, bleach, ammonia, and multipurpose cleanser. In order to perform the test, you will need to apply the different substances to a sealed concrete sample. Since exposure times matter, leave the substances on for various time intervals of 15 minutes, 1 hour, 8 hours, and 2 hours. Remember to seal the concrete sample in the same way as you plan to seal your countertops. You will also need to identify the various substances for accurate testing. While this type of testing does take additional time, testing concrete countertop sealers can help ensure you choose the right product for the job.
