How to Seal Concrete

By Randall Shatto

Sealing concrete is important for the longevity of the material. Once you pour a new foundation, driveway or wall sealing it is the next step. Water, dust and dirt can damage the concrete over time. This can deteriorate, crack and lower the value of your home. Sealing your concrete is a simple procedure that can save you money and time in the future.

Purchase concrete sealer and concrete cleaner. You can choose from several types. Quikrete Multi Surface Concrete Sealer and Drylok Concrete Cleaner & Degreaser are available from Ace Hardware, True Value or other home improvement stores. You can use other products to clean and seal your concrete if you so choose. Be sure to read all directions on the back of the products that you have chosen.

Wait for the concrete to settle. It is important to wait at least 30 days after the concrete has been laid before you seal it. This gives it time to settle, cure and become ready for the sealer.

Wear safety equipment. Before working with the cleaner or sealer, put on your rubber gloves and goggles to protect your eyes and hands when working with chemicals.

Clean the concrete. First, you will need to sweep the concrete. Be sure you remove any excess dirt or debris off the slab you are sealing. Pour your cleaner into your paint tray. The formula should be half cleaner and a quarter of water. Then use your paint roller. Dip it in the paint tray then scrub the concrete with the cleaner mixture. Once you have cleaned any set in dirt or grease off the slab, use your hose to remove the rest of the cleaner. Let dry completely. If you are working during the rainy season, tarp or cover the concrete.

Wash out your paint roller and paint tray. Just like the concrete, these items need to be freshly cleaned and dried before proceeding with the sealer.

Pour the sealer into your paint tray. Use your paint roller to apply to the concrete. You will want a medium coat of sealant placed on the concrete. You will see a small color change. When this occurs, your concrete is sufficiently sealed. Let the concrete dry fully. Cover the material with a tarp and keep pets or humans away from the concrete until it is dry.
