What Is The Difference Between Resurfacing And Polishing Concrete?

hen your existing concrete needs a makeover, there are a few options. Polishing or resurfacing your concrete with a decorative overlay will give it a fresh, clean, new look.

However, one process might be better suited than the other, depending on the condition of the concrete.

To help you decide which finish to choose, we've gathered a list of things to consider.

What Is The Condition Of The Concrete Floor?

The most important factor when deciding which floor finish to choose is the condition of the concrete floor. For polishing concrete, almost all structurally sound concrete can be polished. Suppose your concrete is determined to be too porous and has major flaws such as big patchworks that will still be visible after the polishing and spalled areas that are beyond repair. In that case, your floor will be a better candidate for resurfacing.

If your concrete is determined to be in too poor condition for polishing, resurfacing it with a decorative overlay is the best way to hide the flaws. You can choose from a range of overlay finishes, from micro toppings to thick self-leveling overlays, that will even the floors, cover any damage, and provide a smooth, even surface for your chosen decorative finish.

What Finish Do You Want To Achieve?

Stencils, decorative saw cuts, and stains or dyes can enhance polished concrete and overlays.

If you want a more clean, modern, rustic, or industrial look, polished concrete might be a better option. The finish of your polished concrete floor can be matte, satin, or glass-like.

However, with resurfacing overlays, you have more decorative options. Depending on the type of overlay system and the tools used to apply it, you have the option of an ultra-smooth finish or a heavily textured finish.

The overlays can also be stamped to mimic brick, slate, or stone or seeded with decorative aggregates to achieve a terrazzo-like effect.

If you love the look of polished concrete but your concrete needs to be in better condition for polishing and are not convinced resurfacing is the look you want, you can always choose polishable overlays.

Polished overlays provide a polished concrete look without showing the underlying imperfections. The micro-topping can be installed over any hard surface and easily treated with color or a decorative coating. It is environmentally friendly, mold—and mildew-resistant, and, most importantly, economical.

What Are Your Performance Requirements?

In terms of performance, polished concrete floors are highly durable and long-lasting, especially in high-traffic areas. This is thanks to the densification and polishing process.

Polished concrete floors are also easier to maintain than other types of decorative concrete floors because they require no waxing or sealers. With basic cleaning, polished concrete should retain its luster for years to come.

Conversely, cement-based overlays offer a variety of finishes but also require more maintenance. A sealer or coating is needed to protect them from abrasion and foot traffic. In high-foot areas, frequent use of floor wax or polish might be required to offer extra resistance to patterns and stains.
