How to Tackle Concrete Sealing

Concrete is one of the most durable and versatile building materials. However, if it’s not properly sealed, it can be prone to damage from weather, chemicals, and other factors. Sealing concrete is an essential step you may choose in protecting it from damage and ensuring its longevity, whether it’s a driveway, walkway, or patio. In this article, we’ll discuss the steps you need to take to properly seal concrete.

How To Seal Concrete

Step 1: Prepare the Concrete Surface

Before sealing concrete, you need to ensure that the surface is clean and free of debris. Use a broom or vacuum cleaner to sweep away any loose dirt and debris, and then use a pressure washer or hose to remove any remaining dirt, grime, or stains. If the concrete has been previously sealed, you’ll need to remove the old sealant before applying a new one. Use a concrete stripper to remove the old sealant, and then clean the surface thoroughly.

Step 2: Choose the Right Sealer

There are several types of sealers available, including acrylic, epoxy, and polyurethane. Each type has its own advantages and disadvantages, so it’s important to choose the right sealer for your specific application. Acrylic sealers are the most popular choice for sealing concrete, as they’re easy to apply, relatively inexpensive, and provide good protection against water and UV damage. Epoxy sealers are more durable and provide better protection against chemicals and stains, but they’re more expensive and require more prep work. Polyurethane sealers are the most durable and provide the best protection against abrasions and impacts, but they’re also the most expensive.

Step 3: Repair Any Concrete Damage

Once the surface is clean and you’ve chosen your sealer, check for any cracks or damage in the concrete. It’s important to repair any cracks or holes before you apply the sealer. If you skip this step, the sealer won’t be able to penetrate the concrete properly, and the cracks will still be vulnerable to damage. You can use a concrete patching compound or epoxy to repair the cracks. Follow the manufacturer’s instructions carefully.

Step 4: Apply the Sealer

Once you’ve chosen the right sealer for your concrete, it’s time to apply it. First, make sure the concrete is completely dry before applying the sealer. Use a brush or roller to apply the sealer in a thin, even layer, being careful not to apply too much in one area. If you’re using an acrylic sealer, you may need to apply two or more coats to achieve the desired level of protection. If you’re using an epoxy or polyurethane sealer, you’ll need to mix the two components together before applying. Be sure to follow the manufacturer’s instructions for mixing and applying the sealer.

Step 5: Allow the Sealer to Dry

After applying the sealer, you’ll need to allow it to dry completely before walking or driving on the concrete surface. The drying time will vary depending on the type of sealer you’ve chosen and the weather conditions. In general, acrylic sealers will dry within a few hours, while epoxy and polyurethane sealers may take several days to fully cure.

Step 6: Maintain the Sealed Concrete

Once the sealer has dried, you’ll need to maintain the sealed concrete to ensure its longevity. Regular cleaning is essential to prevent dirt and debris from building up on the surface. Use a broom or leaf blower to remove loose debris, and then use a mild detergent and water to clean the surface as needed. Avoid using harsh chemicals or high-pressure washers, as these can damage the sealer and the concrete surface.

In addition to regular cleaning, you may also need to reapply the sealer every few years to maintain its effectiveness. The frequency of reapplication will depend on the type of sealer you’ve chosen and the amount of traffic the concrete surface receives. Be sure to follow the manufacturer’s instructions for reapplying the sealer, and make any necessary repairs to the concrete surface before doing so.

In conclusion, sealing concrete is an essential step in protecting it from damage and ensuring its longevity. By following these steps, you can properly seal your concrete and keep it looking great for years to come.
