If you're looking to apply concrete countertop sealer to any of your home's countertops, you may be curious about how the task is carried out. Fortunately, with the aid of a few helpful tips, your countertop sealer can be applied in a timely, hassle-free fashion.

1. Perform a Preparatory Cleaning

One important tip to keep in mind when applying concrete countertop sealer is to give your countertop a thorough cleaning before proceeding with the sealer application. Failure to do this will result in caked-on dirt, dust, and other assorted bits of filth being mixed in with your sealer. Concrete countertops can easily be cleaned with a mixture of warm water and mild liquid soap, so there's no reason not to take this precaution.

2. Apply Your Sealer with a Paintbrush or Paint Roller

When it comes time to apply your concrete countertop sealer, it is essential you use the proper tool: a paintbrush or paint roller. While some people will attempt to apply sealer with rags or washcloths, this typically results in a messy, uneven distribution of sealer. Using one of the aforementioned painting tools will ensure your concrete countertop sealer is evenly spread across the entire counter.

3. Carefully Follow Your Sealer's Directions

Although it may seem somewhat obvious, following the directions laid out on your sealer's packaging is vital to the success of this job. So, when it comes to drying time and additional coat applications, do not deviate from the product's instructions.
