Exterior Polished Concrete

What Is Exterior Polished Concrete?

Exterior polished concrete is a type of concrete that has been polished to a high shine. It is done by the process of treating and finishing the surface of a concrete slab to achieve a smooth, glossy, and durable finish suitable for outdoor applications.

The process involves a series of grinding, honing, and polishing steps using specialised equipment and abrasive materials to enhance the appearance. Polished concrete is a popular choice for indoor and outdoor applications, as it is durable, low maintenance, and easy to clean.

Can You Have Polished Concrete Outside?

Yes, you can have polished concrete outside. With proper care, polished concrete can be a durable and beautiful surface for your home. If you hire professionals for this job, you can get an attractive-looking concrete look in outdoor swimming pools, entertaining areas, commercial foyers, external walkways, and outdoor public spaces.

However, there are some things to keep in mind if you choose to do this; polished concrete can be an issue in a few cases, but I have added quick fixes along with them.

  • Polished concrete can be slippery when wet. This is a major safety concern, especially in areas with much foot traffic, such as near pools or spas. You can count on a non-slip additive mixed with the sealer to make polished concrete safer.
  • Polished concrete can be damaged by the sun. The ultraviolet (UV) rays coming from the sun can cause the concrete to fade and crack. To protect your polished concrete from the sun, you should seal it regularly.
  • Polished concrete can be etched by acids. Spills of acidic substances, such as citrus fruits or cleaning products, can carve the surface of polished concrete. To prevent this, you should clean up spills immediately and seal the concrete regularly.

Benefits of Using Exterior Polished Concrete

Many experts recommend polished concrete if you want to utilise the unutilised outdoor space in your home while matching the indoor aesthetics. Not only affordable compared to using tiles but also give you many other benefits.

  • Durability – An enduring surface that can withstand the elements. It is resistant to cracking, fading, and staining.
  • Low-Maintenance – A low-maintenance surface that does not require waxing or sealing. It can be washed with a typical hose and broom.
  • Slip-Resistant – Can be made slip-resistant by incorporating a non-slip additive to the sealer. This is important for areas with a risk of slipping, such as near pools or spas.
  • Customisable – The polish level of concrete can be customised to the desired finish, creating a unique look.

Exterior Polished Concrete Process

Concrete is just concrete until it faces the polishing process and becomes what we admire as exterior polished concrete. But how does it really happen? Well, below is the typical process of exterior polished concrete.

Exterior Polished Concrete

Surface Preparation

The concrete surface is comprehensively cleaned, and any existent coatings, sealers, or contaminants are withdrawn. This step ensures proper adhesion and allows the concrete to be effectively polished.


Coarse grinding is performed using diamond-embedded abrasive pads or discs to remove any surface imperfections, such as bumps, rough spots, or minor cracks. This process gradually levels the concrete and exposes the desired amount of aggregate (stones) within the slab.


Finer-grit abrasives are used to refine the surface and achieve a smoother texture. This step removes the scratches and marks left by the initial grinding, resulting in a more uniform appearance and improved clarity.


Multiple polishing steps follow, utilising finer and finer grit abrasives to create a glossy finish. This process enhances the concrete’s sheen, depth, and reflectivity. Special polishing compounds may also be applied to improve shine and durability.

Densifying and Sealing

A densifying agent may be applied to the polished concrete to strengthen the surface and reduce porosity, making it more resistant to staining and wear. A sealer is then applied to protect the concrete from chemicals, moisture, and UV damage while enhancing its colour and lustre.
