Can I Seal My Patio Bricks?


Whether or not to apply a sealer to a brick patio is strictly a matter of choice and preference. While some people prefer the shiny look of sealed brick, others are more suited by the natural appearance of unsealed, unfinished brick. Brick sealers are available in a variety of finishes to give the patio the look you desire. In addition to changing the look of the brick patio, there are quite a few advantages to applying a sealer.

Why Seal a Brick Patio

  • Applying a sealer to a brick patio has some advantages to not sealing. First, a sealer will protect the surface and texture of the brick. Scratches and stains are much less likely if a sealer has been applied. Spilling oil, food or other substances on a sealed brick patio will be much easier to clean up than on an unsealed brick patio.

    Many sealers include a waterproofing agent which is even more beneficial to the brick patio. Applying a waterproof sealer will not only protect the brick from spills, stains and scratches, but will also protect it from moisture. A waterproof sealer will penetrate the brick, coating the even the inside and tiny passages through the brick to keep moisture out. Reducing moisture in the brick will result in a longer lifespan for the brick patio.

How to Apply Brick Sealer

  • If you choose to seal your brick patio, repeat applications should be done every one to two years for optimal protection. Applying sealer to a brick patio is relatively simple and quick. The patio should be thoroughly cleaned prior to applying the sealer. Failure to properly clean the patio may result in dirt or debris becoming trapped underneath the sealer. The sealer is then applied using a paint roller or paint brush. Apply a thin coat of sealer using light brush strokes. Be sure to back-brush to remove any brush or roller marks on the brick. Two coats of sealer can be applied, if necessary.

    If you wish to have your brick patio sealed but do not feel it is a job you can do yourself, there are a number of companies that will come to your home and apply the sealer to your patio. Check your local phone book for companies specializing in brick restoration.
