Sealing Different Types of Concrete Surfaces 5/5 (1)

Different Types of Concrete Surfaces that need to be sealed.

Decorative Concrete – This is any concrete surface that is not simply a means of construction but that is also altered to enhance its beauty. While still serving as an integral part of the building process such as floors, walls, driveways, or patios the concrete is also transformed into a decorative piece. The altering of concrete to enhance its beauty is accomplished through a number of procedures such as stamping, acid staining, polishing, coloring, overlaying, and more.

Stamped Concrete – Concrete that is altered to look like another material such as brick, stone, slate, flagstone, tile, and wood. To achieve this look, the concrete is normally patterned, textured, or embossed. In addition, a base color is used along with an accent color. Stamped concrete is generally used for driveways, patios, sidewalks, pool decks, and flooring.

Acid Stains – Acid stain on concrete is not a paint or coating but rather a coloring process that involves a chemical reaction. Acids and salts react with the concrete minerals to create a color change. Acid stain can be used to enhance both interior and exterior concrete surfaces. Once the color change has occurred, the surface can be sealed to protect the finish.

Pavers – Concrete pavers more commonly known as “pavers” are a special dry mix of pre-cast concrete that is designed to interlock. Pavers are generally used in exterior hardscape applications. The interlocking pavers are installed on a compacted bed of sand. Sand is also used to create joints much like mortar joints in brickwork. A paver sealer can be applied to lock in the sand joints and harden the entire structure.

Exposed Aggregate – This is a type of concrete finish achieved by increasing the amount of aggregate (stone) in the concrete mix before it is poured. Once partially set, a surface retarder is sprayed on. This allows the concrete underneath to harden but not the surface. Once the underneath concrete is hardened, the top layer of concrete is washed away exposing the internal aggregates of the concrete mix. Exposed aggregate hides stains, cracks and overall weathering much better than regular concrete due to the busyness of the appearance. Yet exposed aggregate is a very aesthetically pleasing finish. Older exposed aggregate surfaces can look just as good as the day they were poured.

Poured Concrete – A composite mix of cement and other materials like fly ash, slag, limestone, water, and chemicals. It is mixed to meet the needs of a desired concrete slab or other surface. It is typically brought in and poured using a cement truck. Concrete can take on many shapes, sizes, and functionalities depending on the job. Forms are set to help the concrete take its shape while a sub base of granular fill or road base is used. Once poured, the concrete surface is smoothed, leveled, and finished to the desired look. Poured concrete is most commonly used for driveways, sidewalks, patios, pool decks, foundations, and retaining walls.

Brick Walls – Brick walls are constructed using bricks and mortar. This type of brick wall construction is commonly referred to as masonry construction. The bricks are normally made of concrete, ceramic, or calcium silicate. Bricks are coated with a cement mix called mortar and stacked on top of one another in layers to create a wall or some other type of building structure. Brick walls can be used for the construction of entire buildings or houses. They are also commonly used for chimney construction, foundations, and more.

    What sealer do you recommend for maintenance of exposed aggregate concrete with a stain/stamp border (integral color) that is mostly used for foot traffic? This is located near the Oregon ocean. The concrete was placed last year.

    Just bought some cement statues that are very white (White cement not applied color) and would like to seal them to retain the white color. What do I use?

    Have a river gravel lanai that needed some stones replaced and restored. They replaced the stones with a dark concrete material, assuring me they could wash the top off with muriatic acid. They could not. Then they used different products to remove the unsightly black mess. It worked eventually, but now the areas treated are no longer black…they are white!!! What can be done to correct this sorry mess??? Help!

    What sealer is recommended for an interior exposed brick wall in a 1910 Philadelphia row home? I am looking to provide a wet look with a matte finish while allowing the brick to breathe and preventing dusting?

      You could try a product like the Surebond SB-6000 but you should call them to confirm first if the application will work for you.
